Design and implementation of energy management system with fuzzy control for multiple microgrid

DGs used in distribution network, it is important for reliable and optimal operation of the distribution system after DGs connected into the system. This work studies the harmonic impact of DG. DG is classified as linear model and nonlinear model is this work from the harmonic analysis perspective. The stage of distortion depends on the internal elements of the DGUs as well as on the characteristics of the grid, loads, and controls, among others. This paper is based on a least square solution using the harmonic domain modelling approach to efficaciously consider explicitly the harmonic characteristics of the DGUs and their direct and cross-coupling interaction with the grid, loads, and the other DGUs using fuzzy logic controller (FL). The simulations and analyses against MAT LAB are presented in order to compare conventional methods to FL.
