Fuzzy Logic Based Energy Management System Design for AC Microgrid

Abstract

This paper dealing with the design of Fuzzy Logic Controller of 25 rules to be applied in Energy Management System for a microgrid system. The primary intention of the model is to decrease the grid power deviations while preserving battery state of charge within the acceptable boundary. As a replacement for forecasting based methods, the proposed method approaches energy rate of change method. The fuzzy controller design parameters are fine-tuned to optimise the predefined set of quality criteria of the microgrid behaviour. A comparison with other methods looking for the same target is presented at simulation level. Modelling, analysis and control are done in Matlab Simulink platform.
