The concept of utilizing microgrids (MGs) to convert buildings into prosumers is gaining massive popularity because of its economic and environmental benefits. These pro-sumer buildings consist of renewable energy sources and usually install battery energy storage systems (BESSs) to deal with the uncertain nature of renewable energy sources. However, because of the high capital investment of BESS and the limitation of available energy, there is a need for an effective energy management 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 minimize 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 model. In addition, a flexible load shifting (FLS) scheme is also developed and integrated into the proposed strategy to further improve 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 demand. To validate the performance of the proposed ^s trategy, the results of IEMS are compared with the well-established energy 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 economical and efficient.

利用可再生能源和电池储能系统改进产消合一建筑的能源管理策略

利用微电网（MG）将建筑物转变为产消者的概念因其经济和环境效益而受到广泛欢迎。这些亲消费者建筑由可再生能源组成，通常安装电池储能系统（BESS）来应对可再生能源的不确定性。然而，由于 BESS 的资本投资较高且可用能源有限，因此产消者建筑需要一种有效的能源管理策略，以最大化建筑物所有者的利润并延长 BESS 的运行寿命。对此，本文提出了一种改进的产消者建筑能源管理策略（IEMS），以最小化 MG 的运营成本和 BESS 的退化系数。此外，为了估计 BESS 的实际运行寿命，本文采用了非线性电池退化模型。此外，还开发了灵活负载转移（FLS）方案并将其集成到所提出的策略中，以进一步提高其性能。所提出的策略针对安装在商业建筑中的并网太阳能光伏 (PV) 和 BESS 供电的交直流混合 MG 的实时年度数据进行了测试。此外，场景缩减技术用于处理与发电和负载需求相关的不确定性。为了验证所提出^策略的性能 ，将 IEMS 的结果与完善的能源管理策略进行了比较。仿真结果验证了所提出的策略显着提高了建筑业主的利润和BESS的运行寿命。此外，FLS通过进一步提高MG所有者的财务利润和BESS的寿命来增强IEMS的性能，从而使产消者建筑的运营更加经济和高效。
