In this paper, an optimal active and reactive power control is developed for a three-phase grid-connected inverter in a microgrid by using an adaptive population-based extremal optimization algorithm (APEO). The low PCC voltage has a larger impact for Strategy I because its power control loop is a current control loop, and the current references depend on the PCC voltage. Most VSG inverters are voltage sources and can help to ma nt and sustainable power system. From then it is given to grid or the. .
