This paper aims to present a comprehensive review of the distribution static compensator connected with solar photovoltaic (SPV) system employed for voltage regulation, power factor correction, and load balancing in the distribution network. The inverter employed with SPV system for supplying active power to the grid/load can be made multifunctional i.e. it also serves as DSTATCOM when SPV power is not available (The arrangement is called PV-DSTATCOM). For such an arrangement the need for the actually installed DSTATCOM for voltage regulation and temporary over voltage control can be either minimized or altogether eliminated, bringing a significant savings for the utility. The intention of this review is to provide a broad view on configuration, topologies, and control techniques to the researchers and engineers working on power quality improvement. More than 100 research publications on the topologies, configuration, control techniques and applications of distribution static compensator have been thoroughly reviewed and classified for quick reference.

Nowadays, customer satisfaction relies on not only the power delivery, but also in the system reliability. It results a number of measures adopted by utility for reliability improvement. Moreover, distributed generators (DGs) are also enhanced to integrate to distribution system because DGs improve system reliability and capability. However, DGs can lead to mis-operation of protective devices and wider outage areas in power system due to increase in fault level. Moreover, system outage is the vital cause which decreases the system reliability. To mitigate escalation of fault level, fault current limiters (FCLs) are installed to limit incremental fault generated by DGs and improve system reliability. However, to enhance effectiveness of FCLs installation, non-dominated sorting particles swarm optimization (NSPSO) is adopted to find the optimal placement of FCLs. Moreover, novel binary particle swarm optimization and continuous particle swarm optimization are performed optimization simultaneously for selecting installed locations. Therefore, three objectives are considered in optimization process consist of to minimize total cost of fault current limiters installed, to minimize total different of margin operating time of main and backup relay pairs and to maximize system reliability. The optimal results are the set of various solutions conform with multi-objective placed in pareto optimal front, and the result show effectiveness of combined continuous-binary NSPSO. The optimization process is carried out on IEEE 33-bus and IEEE-69 bus radial system.

Energy is the prime component for the development of a nation. Enormous amount of fossil fuels, viz. coal, gas, oil, etc. are extracted, converted, distributed and consumed by the society on daily basis for various activities. The limited stock of fossil fuels and its end result as global warming forced scientists to harness energy from nonconventional resources. Renewable energy, such as solar, wind, geothermal, ocean tidal waves are the best proven sources of energy. Solar energy is one of the most abundant and cheap resources among these. Solar energy is converted into electrical energy with the help of photovoltaic solar panels. Solar energy is maximized when the sunrays fall perpendicular on the panel. The rigid fixed type conventional solar panels have restriction to receive maximum sunrays because of changing angle of incidence. Automatic sun tracking system is the solution to harness maximum solar energy by facing the sun whole day.

Every region, country and city is witnessing unprecedented growth in infrastructure that includes predominantly building structures. Global Construction 2030 – forecasts the volume of construction. Global Construction Perspectives and Oxford Economics - shows average global construction growth of 3.9% pa to 2030, outpacing that of global GDP by over one percentage point, driven by developed countries recovering from economic instability and emerging countries continuing to industrialize output will grow by 85% to $15.5 trillion worldwide by 2030. This astounding growth in building structures reflects obviously in energy consumption and in turn carbon footprint. There is a need to assess energy efficiency status of the buildings that would enable taking up appropriate energy conservation measures throughout the lifecycle of a building. In this regard, the traditional on-site physical audit suffers with limitations in terms of deployment, installation, human resource and scalability in overall execution, making it techno-economically less attractive and time consuming.The present paper provides practical application and validation of an innovative tool that enables performance assessment of buildings to uncover energy efficiency improvements in buildings and facilities remotely. This tool uses multi-physics principles wherein entire building is analyzed based on fundamental energy and work transfer principles using laws of thermodynamics, heat transfer and mass transfer. This innovative tool enables cost efficient energy savings through a virtual energy audit conducted remotely.In the present work, the case study from India, in particular academic building, industrial building and commercial building are considered as a candidate for virtual energy audit. The results depict that virtual energy audit is holistic and accurate evaluation and analysis of candidate’s current energy use. The results enable take informed and educated decisions for prioritizing energy conservation measures to improve energy efficiency.
每个地区、国家和城市的基础设施都在经历前所未有的增长，其中主要包括建筑结构。全球建筑2030 -预测建筑数量。《全球建筑业展望》(Global Construction Perspectives)和牛津经济研究院(Oxford Economics)联合发布的报告显示，到2030年，全球建筑业年均增长3.9%，比全球GDP增速高出1个多百分点，这主要得益于发达国家从经济不稳定中复苏，以及新兴国家继续实现工业化，到2030年全球建筑业产值将增长85%，达到15.5万亿美元。建筑结构的惊人增长明显反映了能源消耗和碳足迹。有必要评估建筑物的能源效率状况，以便在建筑物的整个生命周期内采取适当的节能措施。在这方面，传统的现场物理审计在部署、安装、人力资源和整体执行的可扩展性方面受到限制，使其在技术经济上不那么有吸引力，而且耗时。本文提供了一种创新工具的实际应用和验证，该工具使建筑物的性能评估能够远程发现建筑物和设施的能效改进。该工具使用多物理场原理，其中整个建筑基于基本的能量和功传递原理，使用热力学，传热和传质定律进行分析。这一创新工具通过远程进行虚拟能源审计，实现了经济高效的能源节约。在本研究中，以印度为例，以学术建筑、工业建筑和商业建筑作为虚拟能源审计的候选建筑。结果表明，虚拟能源审计是对候选企业当前能源使用情况的全面、准确的评价和分析。结果使采取明智和有根据的决定优先节能措施，以提高能源效率。

The present study was based on the use of TRNSYS software for the simulation of the dynamic thermal behavior of a F2 building in Lokossa, Benin Republic. The results showed that between 00 AM and 07AM, the temperature of the indoor air is approximately 20 ° C and increases gradually until 02 PM when the temperature reaches its peak 30 ° C. However, the total incident solar radiation receives varies from a face to another and the roof received the largest due to its horizontal orientation. The heat received by a face reaches its peaks dependently on its orientation. There is a phase shift in the heat transfer received by the envelope. This is possible due to the thermal inertia of the envelope’s constituent materials, property that allows the building envelope to dampen the heat received and to phase out the transmission time to ensure thermal comfort in the home.

This research focuses on modifications of a conventional biomass burner for a vertical fire-tube boiler to accept multiple fuel with increased efficiency. The selected boiler for this work has thermal power output of 90 kWth using firewood as primary fuel. The main objective is to design and develop multi-fuel feeding system to accept other available biomass applicable to existing burner with minimal modifications of the main structure. After the burner was refitted with the feeding system, the optimum surplus combustion air was studied for three types of solid fuels; corn cob, wood chips and biomass pellets. A breakpoint analysis was conducted for each biomass fuel. It was found that before burner modification, the highest values of thermal efficiency of fire wood burner were 40.52%. After the change of burner feeding in accordance with air input improvements, the thermal efficiency of the burner for corn cob, wood chip and pellets were 54.18 %, 50.46 % and 69.41 % respectively. The semiautomatic fuel feed can be readily utilized for all three fuel types and feed rate could be reduced by 58.1.1%, 58.2% and 70.63% by weight respectively compared with firewood. It is also found that biomass pellets are the most suitable alternative fuel for roasting of parchment coffee with the lowest processing cost in comparison with other biomasses.

The number of Wind Power Distributed Generators are increasingly integrated in power systems because of having environmentally friendly and technically sound characteristics. It is prevalent that the non-optimal size and placement of Distributed Generation (DGs) can cause high power loss and unexpected voltage profile variation on feeder. This research study focusses on the probabilistic approach to design of Distributed Generation (DGs) and its impact on medium voltage (MV) feeders. Monte Carlo simulation based probabilistic power flow considering stochastic nature of wind and solar power generation and uncertainty of load variation are employed. The proposed method is simple that used open source MATLAB software including MATPOWER tools to analyse and design low voltage and medium voltage feeder. This method can furnish several choices to utilities/owners to place WT-DGs and PV-DGs at different suitable nodes. The method will be tested on different case study using Indian practical 22-bus and IEEE 69-bus network and the effect of DGs on the system voltage profile and loss are investigated accordingly.

Energy demand in Malaysia has increased steadily over the past years attributed to consistent decline in reserved crude oil and natural gas resources. However, till do date the primary energy supply still comes from coal, natural gas and crude oil while the contribution of renewable fuel in National energy mix is only 10% which is 2080 megawatts. Efforts have been taken by Malaysian government to increase the electricity generation through renewable energy sources; one of it is implementation of feed in tariff mechanism, where it permits independent power producers to generate electricity from renewable sources and sell to national grid. Currently, most of power producers considering palm mill effluent as a promising source to produce biogas for electricity generation via gas engine. The aim of this paper is to address the current progress of biogas industry in Malaysia, issue and challenges and way forward to accelerate the growth of biogas industry. Besides, this paper also highlighted cattle manure as potential feedstock for biogas generation and barriers to build biogas plant in cattle farm for electricity generation. Finally, highlighted the importance of co-digestion technology for Malaysia for sustainable biogas production.

Environment is the sum of substances forces and conditions external to an organism that influence its various components and constitutes a multi-dimensional system of complex relationships in a continuing state of change. Manganese is one of the major mineral deposits occurring in the Indian sub-continent. It has played a great role in development of civilization and industrialization. The occurrence of Manganese ore in Dongri Buzurg Mine is proved by the way of exploration and its production has important role in the steel industries. Mining has it vary base, destruction of the part of environment, and mineral processing, which deals with the recovering with the small parts of mined material that is of use to mankind and discharging rest as waste, both the process has have an impact on the environment. MOIL Limited has been using technologies for sustainable development since its inception. The sustainable development framework (SDF) is addressing on various issues begins with grant of mining lease to final mine closure plan stages of mining life cycle. The SDF is also refers on economics, environment and social impacts of mining. It is also causes the environment degradations that lead to destruction of wildlife habitat. To achieve the integration of socio-environmental-economic factors it is essential to develop and implement SDF. By recent amendment of Mines and Minerals (Development and Regulation) Act, 1957, implementation and evaluation of SDF have become mandatory. SDF is modeled by international agencies International Union for the Conservation of Nature and Natural Resources (IUCN) and International Council of Mining and Metal (ICMM) and tailored for Indian conditions. Some of the aspects of SDF are covered in a case study for development of green corridor for the pollution abatement at Dongri Buzurg Opencast Mine.
