Abstract
In this paper, real-time power management systems (PMSs) are proposed for both grid-connected and islanded operations of AC microgrid (MG) by considering the maximum utilization of renewable energy sources and storage systems prioritization of critical loads together. The advantage of the proposed PMSs is instead of focusing on a market-based optimization problem, it is emphasized on the instantaneous supply-demand balance for enhancing MG stability and providing better power quality. Real-time simulation on a real-time digital simulator is carried out to prove the effectiveness of the proposed MG PMSs. The results show that through the implementation of the proposed PMS, maximum use of renewable energy sources and energy storage systems are ensured by maintaining a proper balance between supply-demand.
