The concept of utilizing microgrids(MGs)to con-vert buildings into prosumers is gaining massive popularity be-cause of its economic and environmental benefits.These pro-sumer buildings consist of renewable energy sources and usual-ly install battery energy storage systems(BESSs)to deal with the uncertain nature of renewable energy sources.However,be-cause of the high capital investment of BESS and the limitation of available energy,there is a need for an effective energy man-agement strategy for prosumer buildings that maximizes the profit of building owner and increases the operating life span of BESS.In this regard,this paper proposes an improved energy management strategy(IEMS)for the prosumer building to min-imize the operating cost of MG and degradation factor of BESS.Moreover,to estimate the practical operating life span of BESS,this paper utilizes a non-linear battery degradation mod-el.In addition,a flexible load shifting(FLS)scheme is also de-veloped and integrated into the proposed strategy to further im-prove its performance.The proposed strategy is tested for the real-time annual data of a grid-tied solar photovoltaic(PV)and BESS-powered AC-DC hybrid MG installed at a commercial building.Moreover,the scenario reduction technique is used to handle the uncertainty associated with generation and load de-mand.To validate the performance of the proposed strategy,the results of IEMS are compared with the well-established en-ergy management strategies.The simulation results verify that the proposed strategy substantially increases the profit of the building owner and operating life span of BESS.Moreover,FLS enhances the performance of IEMS by further improving the financial profit of MG owner and the life span of BESS,thus making the operation of prosumer building more economi-cal and efficient.
