Abstract:

Microgrid is a group of interconnected loads and distributed energy resources (including microturbines, diesel generators, energy storage, renewable resources, and all other kinds of distributed energy resources) at distribution level with defined electrical boundaries that has black start capacity and can operate in island mode and/or grid-connected mode.

Because of the uncertainty, intermittent, and discontinuity of the renewable resources, transient disturbance and dynamic disturbance exist in the microgrid. For the fault current is small in the system and the microgrid has very little inertia, the disturbance control and fault protection of microgrids are more difficult than the ones of traditional grids.

The most challenging part of protection and dynamic control of microgrids is figuring out whether a fault or disturbance is occurring in the system. In the microgrid, there may appear transient characteristics similar to the transient and dynamic disturbance at the initial faults. If there is a fault, the transient disturbance control should be used to prevent the system from collapsing and make sure the right breakers should be tripped. But if there are transient and dynamic disturbances, even the initial characteristics of the transient and dynamic are very similar to the fault ones, the breakers should not be tripped.

So that Mr. Zheng has been leading his team to propose and develop the dynamic disturbance control, transient disturbance control and fault protection technologies, and they all have been well applied in practical projects. The main innovations are as follows:

 (1) Relying on the dynamic disturbance control technology of the energy storage system, it can achieve safe and stable operation under the condition of high permeability of renewable energy, and can support 100% consumption of renewable energy generation in microgrid system.

      (2) Through real-time load and power generation monitoring, analysis and control technology, relying on power and energy storage energy to effectively suppress transient disturbances and dynamic disturbances, respectively, to achieve unplanned seamless switching from grid connected mode to island mode or vice versa (time less than 10 milliseconds), Improve the safe and stable operation level of the system.

 (3) Based on the Park transformation and the fault identification technology of branch current and voltage harmonic rapid changing rate, the precise positioning and fast isolation of the fault components of the microgrid are realized.

(4) Based on the power and load side comprehensive treatment technology, the total harmonic distortion rate (THD) of voltage and current is less than 3% when operating on an island.

The microgrid dynamic disturbance control technology, transient disturbance control technology and fault protection technology have been evaluated by domestic and foreign experts as reaching the international leading level.

Abstract:

Hydrogen is being seen as a key future for reducing our carbon emissions and governments are seriously considering repurposing existing gas networks to pure hydrogen so that it can be used by industry, in homes and businesses, and in the energy sector. However, unlike other energy vectors such as electricity, hydrocarbon gases and district heating, high-purity hydrogen has not been deployed at large scales anywhere in the world. This puts hydrogen at a distinct disadvantage. Any attempt to replace natural gas with hydrogen will require a compelling case to compensate for this lack of experience.

This article explores the importance of natural gas to our energy systems and the benefits of hydrogen, which could significantly decarbonise our heating and reduce over-dependency on natural gas. These include: (i) Hydrogen can use much of the existing gas infrastructure, (ii) Hydrogen is a very versatile fuel which can be used by households, industry and businesses (iii) Hydrogen can be produced in large volumes (iv) Hydrogen compares well with other low-carbon heat technologies. This paper considers a number of key questions which need to be addressed before attempting any large-scale deployment of hydrogen to retrofit homes and businesses.

Abstract:

The present review article makes an attempt to comprehensively review various aspects of biomass energy sources, environment and sustainable development. This includes all the biomass energy technologies, energy efficiency systems, energy conservation scenarios, energy savings and other mitigation measures necessary to reduce emissions globally. An attempt has been made to review the current literature regarding the ecological, social, cultural and economic impacts of biomass technology. The environmental problems are increasing. Nevertheless, some residues have negative effects and should be treated to preserve a durable environment. Hence, sensibility and legislative text to organise the treatments of industry activities waste should be more reinforced.

This study highlights the energy problem and the possible saving that can be achieved through the use of biomass sources energy. Also, this study clarifies the background of the study, highlights the potential energy saving that could be achieved through use of biomass energy source and describes the objectives, approach and scope of the theme. The purpose of this study, however, is to contribute to the reduction of energy consumption in buildings, industry, and agriculture and identify biomass as an environmental friendly technology able to provide efficient utilisation of energy in the buildings sector, promote using biomass technology applications as an optimum means of heating and cooling. Recent attempts to stimulate alternative energy sources for heating and cooling of buildings has emphasised the utilisation of the bio-energy from agricultural residues, industry wastes, forestry and other renewable energy sources.

The adoption of green or sustainable approaches to the way in which society is run is seen as an important strategy in finding a solution to the energy problem. The key factors to reducing and controlling CO2, which is the major contributor to global warming, are the use of alternative approaches to energy generation and the exploration of how these alternatives are used today and may be used in the future as green energy sources.

Abstract:

Land leveling is one of the most important steps in soil preparation for agricultural and other purposes. . New techniques based on artificial intelligence, such as Artificial Neural Network, integrating Artificial Neural Network and Imperialist Competitive Algorithm (ICA-ANN), or Genetic Algorithms (GA-ANN), or Particle Swarm Optimization (PSO-ANN) have been employed for developing predictive models to estimate the energy related parameters and the results were compared to SPSS and Sensitivity Analysis  results. In this study, several soil properties such as cut/fill volume, compressibility factor, specific gravity, moisture content, slope of the area, sand percent, and swelling index were measured and their effects on energy consumption were investigated. Totally 90 samples were collected from 3 land areas by grid size of 20m×20m. The aim of this work was to develop predictive models based on artificial intelligence techniques to predict the environmental indicators of land leveling . Results of sensitivity analysis illustrated that only three parameters consist of soil density, soil compressibility, and soil cut/fill volume had meaningful effects on energy consumption.  Among the proposed methods, the GA-ANN had the most capability in prediction of the environmental energy parameters. However, for prediction of LE and FE the ANN and ICA-ANN algorithms had better performance

 .  On the other hand, SPSS software had higher R 2 value than Minitab software and sensitivity analysis and in fact close to the ANN values. Keywords: Energy; Imperialist competitive algorithm; Sensitivity analysis; ANN; Land levelling; Environmental indicators.

Title: A New Perspective on Electric Power

Time : 11:40-12:00

Biography:

Per Ribbing received his Licentiate degree in April 2019 after publishing his licentiate thesis: “Climate Change Leadership – the case for Electrification” and is currently writing his doctoral thesis on the same subject: Climate Change Leadership and the role of Green Power in the sustainable transition from fossil to renewable energy. As a Keynote Speaker on the New Paradigm on Electric Power, or Consumer Power in the Power Market, Ribbing has had a number of international missions, e.g. London 2018 and Zürich 2019. In November 2019 he gave Keynote presentations in Barcelona, Rome and Berlin. To all of the conferences he went by train. “Use your brain – go by train” is his favourite one-liner. Sir Ribbing stopped flying in 2011. In 2008 he was invited Keynote Speaker at TIEF-6 in Tsuruga, Japan. He took the train from Stockholm to Japan.

Abstract:

In the old, physical, way of regarding the Product Electricity; as being similar to water flowing in pipes, the statement “All power mixes on the grid!” held true. However, from a market and consumer power point of view, from an economic view of the product that we purchase (i.e. the Product Electricity), that statement is false. [1 ] Electricity which is audited; Production vs Consumption, does not mix with any other electricity. Only electricity which is not audited does mix. The anonymous agents which are the carriers of the purchased Product Electricity, i.e. the kWh:s, are mixed. The product itself (the electricity) is not mixed. [2]

This new perspective is not intuitively easy to understand, especially not for electrical engineers or anyone working in the power sector. Nevertheless, it is the correct way to understand the new situation with deregulated power markets offering different “colours” of power, i.e. electricity with different environmental loads.

In this new situation the new perspective on the product electricity shows that there exists a possible choice of not consuming any coal power.

However, the market based methods for reporting purchased electricity do have shortcomings and in this article we propose a concrete solution to the most apparent problem; that it is possible to buy only the Guarantee of Origin (GO), separate from the Product Electricity itself.

The fact that transactions like that are both possible and correct (in theory) they do not increase the acceptance, nor the understanding of how it is actually possible to not purchase and consume any coal power. Furthermore, the ongoing important scientific discussion about consumer power on the power markets is hindered.

Abstract:

Statement of the Problem: Renewable energy is progressively deemed necessary for fulfilling the current and upcoming energy demands. Amongst different renewable energies, solar photovoltaic (PV) is one of the cleanest, unlimited, emission-free, readily, reliable and widely available renewable energy resources. Grid-tied PV systems account for 99% of the whole established capacitance in comparison with 1% of the standalone systems. Grid-tied PV systems are generally categorized into two types, the galvanic isolation and non-isolation/transformerless systems, the latter having some advantages over the former, e.g. small size, weight, low cost and high efficiency. However, leakage current problem is one of the most important challenges in transformerless system which may cause some problems. Power electronics converter topologies play a significant role in restriction of this current. Therefore, a variety of state-of-the-art converter topologies with the ability to overcome this issue are reviewed in this work. Then possible improvements are investigated and proposed for several important aspects such as efficiency, reliability, power quality, cost, weight, velum, and leakage current problem.

Methodology and Theoretical Orientation: A comparative study is done for a wide range of grid-connected PV power electronics converters utilizing computer simulation and calculation as well as reviewing scientific publications.

Findings: This comprehensive research gives a clear picture on the advancement of power electronics converters for the next generation grid-tied PV systems with detailed analytical comparisons. These include the number of power devices and components, voltage stress on semiconductors, current stress on inductors, efficiency, shoot-through issue, leakage current suppuration, optimum design, THD analysis, compactness, and cost-effectiveness.

Conclusion and Significance: The improvement of the whole PV systems will be accelerated with the understanding of functions, limitations, and benefits of grid-connected PV power electronics converters. Therefore, various state-of-the-art topologies introduced in recent years are reviewed and investigated in detail here to give insight into researchers and industries, along with highlighting future trends.

Abstract:

In 2009 the UK Intellectual Property Office introduced a “Green Channel” for fast-tracking patent applications relating to inventions that have environmental benefit.  After an initial uptake, the indications are that the level of activity has reached a steady-state.  Meanwhile, in 2012 the European Patent Office introduced a scheme for searching the patent literature for sustainable technologies, and in particular climate change mitigating technologies (CCMT).  Unfortunately, by several measures, the patent data shows a worrying decline in activity since 2012 everywhere except in China. 

Patents are important for underpinning investment in technology, and CCMT and environmentally beneficial technologies are no exception.  The European Commission has announced a €10 billion innovation fund for demonstration of innovative low-carbon and carbon capture technologies, with the first call for proposals to be in 2020.  It will take time for this to flow through to inventions that will show up in the data.

The challenges of climate change will require innovative solutions. So far the patent filing data does not seem to indicate that industry is rising to this challenge. This presentation will set out the data and test this hypothesis.

Title: Waste as a renewable energy resource, the first step towards a new business model

Time : 12:40-1:00

Biography:

IOSUD, Universitatea Valahia din Târgoviște, România

Abstract:

Abstract: An increased level of attention, globally, regarding environmental issues leads to the idea that utilizing green energy represents a first step towards the development of new business models. Backed by an unprecedented technological boom, the accentuated dependency of humankind on finite energy sources becomes a reality of contemporary society. The green economy represents thus a new developmental niche in the business area. Therefore, the objective of decoupling the economic growth from the natural resources’ consumption, becomes the main direction for a sustainable economy. On that account, promoting new eco-efficient business models brings enterprises economic advantages.

The purpose of this research paper is to identify the main action paths that economic enterprises can pursue to obtain a competitive advantage by rightly managing environmental issues.

First, the main theoretical points of view concerning renewable energy resources are analyzed.

Following that, the means through which enterprises can obtain a competitive advantage are explained, covering the progressive development process of new business models and the creation of platforms for future business practices.

Lastly, four new strategies are suggested, which enterprise can use to increase their economic performance, by correctly managing and actioning upon existing environmental issues.

The research backing this article reaches thus two important conclusions regarding resource management and the use of green energy:

1.         The future economic competitive edge will belong to those that will understand and take actions considering that the assumption of infinite resources is not feasible in a finite space.

2.         In the economic landscape, green energy represents the most important form of capital, and the economy should be a mean for sustainable development and not a finality in itself.

Key terms: green energy, resource management, eco-efficiency, competitive advantage

Biography:

Yulnafatmawita is a lecturer at Faculty of Agriculture, Universitas Andalas in West Sumatra INDONESIA.  She worked on quantifying CO2 emission from agricultural land and joined the CRC-GHG in Australia during her PhD Program.  Upon graduation, she came back to her university and she focuses her research on OC sequestration and the impact on soil physico-chemical properties at some types of land use in wet tropical region.

 

Abstract:

Statement of the Problem: Use of fossil energy in human activities has increased CO2 concentration in earth atmosphere causing global warming.  An alternative way to counter the increasing amount of CO2 in atmosphere is by improving area of green landscape, such as tea plantation.  Tea is mainly planted as a cash crop, but it can reduce CO2 atmosphere and increase C sequestration in soil.  Since tea can stand >25 years old, it can consume high amount of CO2 atmosphere during photosynthesis process.  Then, the litters (leaves and small branches) produced either which fall naturally or after being trimmed, will contribute OC to soil.  Since the soil is not cultivated during the entire life of tea, the OC will be accumulated by time, even in sloping area.

Methodology & Theoretical Orientation: This research was conducted using survey method, on which soil samples were taken at 15-25% slope level under 3 different age (9, 21, and 36 years old) of tea plantation (purposive sampling) in a wet tropical area (>3,000 mm annual rainfall)  Solok Regency, Indonesia.  The area is located on the slope of mount Talang (1200-1400 m asl).  Soil was sampled from 0-30 cm soil depth.  Soil OC and BD were analysed, and then calculated the OC sequestered in each soil depth by using formula suggested by Yulnafatmawita and Yasin (2018).  As a comparison, soil samples were also taken from secondary forest nearby.

Findings: Organic carbon sequestered under tea plantation increased by increasing crop age from 9 to 21, and to 36 years old.  The amount of OC sequestration under tea plantation was much higher than that under secondary forest.

Conclusion & Significance: Tea plantation in sloping area under wet tropical region can sequester much higher (1.95-3.16 times) OC in the soil than that under secondary forest nearby.

Abstract:

Organic waste (kitchen, garden/lawn, and agricultural) composting has been done in the current study in which passive air vessel has been applied to manage organic waste. The method was used with some innovations to increase the efficiency while keeping the process cost effective. Compost Seeds were also prepared by using vegetable waste and food scrap as substrate to enhance the degradation of waste. Initial analyses of waste i.e. weight, moisture content and bulk density measurements were carried out to retain best balance of C/N ratio and moisture. The experiment was then established followed by daily measurement of temperatures, weekly measurement of evolved CO2, weekly turning and application of moisture. The matured compost was analyzed on the basis of physicochemical parameters such as color, moisture content, bulk density, water holding capacity, pH and electrical conductivity. Exceptional results were seen with bulk density of 864.62±22.30 lbs/cu yd, moisture content 49.30±0.78 %, water holding capacity 138.70±5.73 %, pH 10.23±0.31 and electrical conductivity 7.46±0.025 dS/m which means that it is an efficient method and would be best practicable solution for the management of organic waste. This composting technique was less labor intensive, required less installing space and did not affect by unfavorable weather conditions due to its efficient design. It was included manual turning to obtain quality compost yield within short time period due to high temperature retained within vessel.
