Fuzzy Based Decision-Making of Energy Management for Regional Energy Systems with Renewable Generation and Installed Storage Systems

The electricity system with penetration of a massive number of renewable generation sources needs to consider various demands, such as power generation efficiency, the service life of energy storage devices, and its impact on the main grid. Therefore, the control of various distributed units in microgrids is a comprehensive multi-objective problem. Taking into account the natural indirectness of new energy, the randomness of predicted loads, and the time-varying nature of electricity prices, this paper proposes an optimized fuzzy control (OFC) system to achieve power flow optimization of microgrids and maximize comprehensive benefits. Simulation experiments show that the proposed optimized fuzzy control strategy can better achieve microgrid power flow control and meet the requirements of multi-objective optimization.
