The global acceptance of solar and wind resources for power generation has continued to increase due to the fluctuation of world oil and gas prices, recent advances in technology, high prices of fossil fuels, no direct greenhouse gas emission from solar and wind resources and government policies to support utilisation of renewable energy resources (RESs). In recent times, RESs have become a potential alternative to supply electricity to the rural communities where the extension of transmission and distribution lines is difficult due to technical and financial barriers. In view of this, this study deals with the optimisation of net present cost (NPC), fuel cost, operation cost and cost of energy (COE) of the hybrid system which consists of photovoltaic (PV), wind turbine generator (WTG), diesel generator and battery storage system. A hybrid power system is designed in this research work to serve a remote community. The optimisation of the key performance indicators of the proposed hybrid power system is done by using the hybrid optimisation model for electric renewable (HOMER). The results obtained from this research work are analysed to select the best options among the available configurations based on the lowest NPC and COE produced by each configuration. The simulation results from several case studies show that incorporation of PV and WTG have reduced the operating cost of the system. ; http://digital-library.theiet.org/content/journals/joe ; am2018 ; Electrical, Electronic and Computer Engineering

Decision analysis tool is utilised for the design and analysis of a microgrid with a perspective of sustainable development for a remote location in the hilly terrain of Himalayas. The microgrid design is based on the locally available energy resources, such as solar, wind, running water streams to meet the electrical load demand. The village selected has no access to electricity till date. A door-to-door survey is conducted to project the current and future load demand of the community. The complexity in designing sustainable energy system due to the inclusion of multiple criteria with multiple objectives and scenarios has increased to a great extent. Involvement of multiple stakeholders with differing views and various factors such as social, technical, environmental, economic and political/institutional, makes the process more tedious. For a successful design of the microgrid for such locations, a synergy needs to exist between differing viewpoints of stakeholder when multiple criteria with various scenarios are considered. Multiple criteria decision analysis tools are best suitable for such scenarios especially for energy planning based on renewable energy technologies. The process outlined in this paper will be helpful for successful design of sustainable microgrids for unelectrified and rural location in developing nations. ; http://digital-library.theiet.org/content/journals/joe ; am2018 ; Electrical, Electronic and Computer Engineering
