Fuzzy Logic-Based Controller for BESS and Load Management in a Microgrid Economic Operation

Battery energy storage systems (BESS) play an essential role in effectively managing the power of a microgrid, maintaining a balance between fluctuating power generated from the distributed energy resources and load demand. By using this system in the time-of-use rate context, it can achieve excellent savings. This paper proposes a fuzzy logic-based algorithm developed for the Battery and Load Management System to support the operation of a microgrid with photovoltaic (PV) farm generation. Also, a comparison of financial cost savings is discussed. The software MATLAB/Simulink® was used to develop and simulate the different scenarios. Results demonstrate that the use of fuzzy logic improved the system since it was able to manage the loads and allow a lower-cost operation properly.
