Energy Internet-Based Load Shifting in Smart Microgrids: An Experimental Study

This study investigated a grid-connected smart microgrid (MG) system integrating solar photovoltaic (PV) panels and battery energy storage (BESS) as distributed resources (DERs) to locally serve residential loads. The load-shifting demand-side management (DSM) technique was employed effectively manage the load appliances. proposed algorithm relies on minimum price incentives allow customers allocate their appliances economically during periods. considers waiting times tariff periods for appliances, calculates precise operating durations each appliance, prioritizes powering from MG first, followed by main grid. comprises two non-shiftable three shiftable When power is insufficient activate all loads, transfers remaining unsupplied with low-priced energy. Energy Internet concept adopted monitor usage when customer unable check accuracy of meter supervising system’s features on-site. comprehensive enables management, continuous monitoring, awareness, cost saving. Six cases were studied, both numerically experimentally, varying generation pre-scheduling periods, without DSM application. In cases, implemented save costs at least 50%.
