摘要

为研究完全去中心化的点对点(peer-to-peer，P2P)能源市场中产消者的最优清算问题，重点解决产消者内部的协作和在P2P市场中实现社会福利最大化的挑战，采用了一种新的平行、分布式的交替方向乘子法(alternating direction method of multipliers，ADMM)，推导出P2P市场的交易机制。该方法考虑每个产消者的效用函数，并引入分布式发电机(distributed generator，DG)和电能存储系统(battery energy storage system，BESS)。算法中每个产消者通过迭代与其相邻的产消者同步交换少量信息，并优化以满足不同的需求。通过对6-peers系统的数值验证，证明了所提出方法的有效性。与基于池的交易机制相比，完全去中心化的P2P问题在单位时间内交易电量提升了160%，社会福利从－9.47元增加到32.43元。

Abstract

In order to study the optimal clearing problem of consumers in a fully decentralized peer-to-peer (P2P) energy market, this paper focused on solving the challenges of cooperation among consumers and maximizing social welfare in P2P markets. A new parallel and distributed alternating direction method of multipliers (ADMM) is adopted to derive the trading mechanism of P2P market. This method considers the utility function of each prosumer, and introduces a distributed generator (DG) and a battery energy storage system (BESS). In the algorithm, each prosumer synchronously exchanges a small amount of information with its neighboring prosumers through iteration and optimizes to meet different requirements. The effectiveness of the proposed method is demonstrated by numerical verification of the 6-peers system. Compared with the pool-based trading mechanism, the fully decentralized P2P problem increases the transaction power by 160% per unit time, and the social welfare increases from -9.47 yuan to 32.43 yuan.
