Abstract

Highlights: Ownership plays a significant role in battery sizing for P2P energy sharing. Three battery ownership structures are analysed for a P2P and P2G network. Battery sizes are optimised for a P2P energy sharing network. Maximum NPV is obtained when each user owns a battery in the P2P network. Abstract: 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.
