A Power management Strategy for Interconnected Microgrids

Abstract

With the evolution of microgrids (MGs), the interconnected operation of MGs is becoming a promising approach for the smart grid. The purpose of this paper is to propose a power management strategy for interconnected MGs. A case study, compromising three MGs is considered. Each MG includes Renewable Energy Sources (RES), a battery Lithium ion (Li-ion) and diesel generator (DG). Using the power sharing framework and considering the local objectives of multiples MGs, the proposed strategy aims to maintain the power equilibrium between consumption and production in each MG via bidirectional interaction between interconnected MGs and the main grid. Results confirm the performance and the robustness of the proposed method.
