Voltage control in micro-grids

It is estimated that around 400 million people have no electricity and will not have access to electrical power resources in the near future. This precludes improvements in living standards and business opportunities as without a stable and reliable electrical power source, connectivity to the global information network is not possible. Similarly without electrical power, mechanization for water supply and other agricultural business opportunities, medical resources other modern resources such as refrigeration are not possible. In such small communities, if access to the available energy is not equitable, then this can create ill-will that breaks down the traditional co-operative nature that is needed for success in rural India. The main aim of the project is to investigate the modelling system and strategy for an Indian stand-alone village based micro-grid and its voltage stability. This is to provide the local people’s electricity needs in the rural areas of that particular state. Micro-grid networks are equipped for producing sufficient energy to better the life ambitions of a small number of connected clients. The project also aims at approaching the challenge of rural electrification through the use of micro-grids within the local generation source. The proposed DC micro-grid has been modelled and simulated using the Homer Energy Software. This Homer energy software performs the various tasks in an accurate manner by choosing the best possible alternatives and sorting out them optimally. The results showed that the renewable energy sources would be feasible option when compared with conventional energy sources for distributing the power in rural parts of India. Finally the various capital costs have been presented for achieving the best economic viability of the proposed DC micro-grid system
