Abstract

This letter presents new perspectives on power control for AC microgrid considering operation cost and efficiency simultaneously. A multi-objective optimization model is first established. Then optimal operation conditions are derived by Lagrange Multiplier Method. Furthermore, a self-optimization droop control strategy with subject to optimal operation conditions is proposed to improve the overall operation performance. Simulation and experimental results validate the effectiveness of the proposed optimization method and self-optimization droop control strategy.
