Existing studies have shown the benefits of battery energy storage systems (BESS) inclusion, but do not consider optimal BESS sizing and operation in a peer-to-peer (P2P) energy sharing network under different BESS ownership structures. Under the P2P framework, two different BESS ownership structures, namely the ESP owned structure and the user owned structure are investigated in this study, which are compared to the traditional user owned BESS under the peer-to-grid (P2G) framework. It is found that in campus buildings with a P2P energy sharing network, the user owned BESS exhibits the highest NPV comparing to the other two BESS ownership structures. The ESP owned structure is economically less beneficial, but provided the opportunity for the prosumers to engage in P2P energy sharing and reduce their energy costs without a BESS investment cost.

现有研究显示了包含电池储能系统（BESS）的好处，但没有考虑在不同BESS所有权结构下的对等（P2P）能量共享网络中的最佳BESS规模和操作。在P2P框架下，本研究研究了两种不同的BESS所有权结构，即ESP拥有的结构和用户拥有的结构，并将其与对等网格（P2G）框架下的传统用户拥有的BESS进行了比较。结果发现，与其他两个BESS所有权结构相比，在具有P2P能量共享网络的校园建筑中，用户拥有的BESS展现出最高的NPV。ESP拥有的结构在经济上没有太大好处，但为生产者提供了参与P2P能源共享并降低能源成本的机会，而无需BESS投资成本。
