Abstract\nA microgrid (MG) is an independent power network that uses distributed energy sources preferably renewable sources available to meet the local load demand. MGs are operated with grid or islanded mode. The MG needs fast and efficient controllers for effective power management under variable load and dynamic operating conditions. This paper presents detailed analysis of droop control and an optimization technique for effective control and size reduction of components in MG structure. The controller parameter optimization is obtained using Yin-Yang-Pair optimization with Particle Swarm Optimization (YYPO-PSO). The simulated performance of the proposed system using MATLAB/Simulink is presented to demonstrate the capability of the optimized controller compared with traditional methods.
