Efficient Energy Management in a Microgrid

摘要

Small scale renewable energy sources like photo-voltaic panels, wind turbines, etc can be easily installed on home roof top and such architecture can minimize cost of energy and load on the main grid. Our approach is to generate energy at home through renewable energy (RE) resources and store surplus energy in the battery bank. If RE generation sources and battery reserve fails to satisfy the load, then power is supplied by the main grid. The major work is to develop an autonomous system that can manage all these sources effectively and efficiently. Despite many advantages of renewable energy sources its drawback is that these sources are weather and climate dependent. Night hours, clouds, wind speed, fog, etc are the factors that effect the performance of renewable energy sources with big impact. This research is based on a group of three prosumers who can generate energy via RE sources at home, stores it in a battery bank and takes the extra energy from nearby grid to fulfill the local demand if it is required. A heuristic algorithm is proposed and implemented for this study.
