Distributed Energy Management of P2P Energy Sharing in Energy Internet Based on Cloud Energy Storage

Abstract

Cloud energy storage (CES) has recently been proposed as one of the most economic saving techniques for peer-to-peer (P2P) energy sharing and coordination in energy internet. By transforming traditional consumers into self-sufficient customers and utility customers, CES enables transactions between customers and utility company, as well as among customers. In this paper, an architecture and operational technology which support P2P energy transactions are suggested based on the case of CES. With the aim of shared and virtually integrated CES among individual customers, a distributed algorithm is proposed to achieve higher renewable energy penetration and economic saving, in combination with alternating direction method of multipliers (ADMM). On the basis of a real-world dataset of renewable energy and real-time electricity price, numerical results show the effectiveness of the proposed framework in terms of economic saving for a long time application.
