摘要/Abstract

摘要：

分布式电源、储能和柔性负荷的集成赋予了需求侧灵活调控能力,使其能够以产消者身份进行电能共享,从而促进电力资源的优化配置。为此,针对电能共享市场的交易机制进行研究,文章提出了基于价值认同的需求侧电能共享分布式交易策略,旨在降低电力市场的交易成本并提高市场效率。首先,基于剩余理论设计了边际价格驱动下的电能共享模式,同时基于最优反应函数建立了市场博弈模型,揭示了市场无序竞争导致的无谓损失。对此,提出了价值认同机制以提高电能共享市场的运营效率,并设计了基于一致性算法的分布式交易策略以实现产消者间的去中心化交易,从而保护用户的隐私安全。最后,通过数值仿真验证了所提交易策略能够实现电能共享市场的帕累托改进并促进电力资源的优化配置。

Abstract:

The integration of distributed generation, energy storage and flexible load endows the demand side with the ability of flexible regulation and control, enabling it to share electricity as a prosumer, in order to promote the optimal allocation of power resources. Therefore, this paper studies the transaction mechanism of power sharing market, and proposes a distributed trading strategy based on value recognition mechanism for power sharing at demand side, aiming to reduce the transaction cost of power market and improve the market efficiency. Firstly, the electricity sharing mode driven by marginal price is designed according to surplus theory, and the market game model is established on the basis of best reaction function, which reveals the meaningless loss caused by disorderly competition in the market. In this regard, a value recognition mechanism is proposed to improve the operation efficiency of power sharing market, and a distributed transaction strategy based on consistency algorithm is designed to realize decentralized transaction among prosumers, so as to protect the privacy of users. Finally, numerical simulation shows that the proposed trading strategy can achieve Pareto improvement of electricity sharing market and promote the optimal allocation of power resources.

Key words: electricity market, prosumer, power sharing, trading mechanism, consistency algorithm
