Recent advancements in the micro grid are aiding the power system in case of reliability and cost efficiency. Since the micro grid is an interconnection of various renewable resources, the system to be analysed consists of biogas as a renewable resource. In this project an electrical system is analysed for efficient power usage (between electrical grid and bio gas generation) and cost minimisation during peak hours. Efficient usage of power and cost minimization is attained using optimal power flow analysis. This project analyses the micro grid considering grid constraints such as Real and Reactive power loss minimization, bus voltage security. The aim is to compare the existing system and proposed system and their differences in cost during peak hours. The software used for analysis is ETAP.
