摘要
绿色电力交易是厘清可再生能源绿色属性、激励能源低碳化转型的重要举措。当前,微网的分布式可再生能源消纳方式仍以“自发自用,余量上网”为主,未能合理量化分布式可再生能源的绿色属性,也未能充分利用需求侧消纳绿色电力的诉求和潜力。为此,提出了考虑绿色属性的多微网间电能可信自治交易方法。首先,建立了微网间绿色电力交易机制,以交易手段引导绿色电力资源的合理配置;然后,提出了基于纳什议价的微网间绿色电力交易滚动出清及结算方法,保证绿色电力交易的资源配置的最优性以及市场红利分配的公平性;最后,建立了基于联盟链的绿色电力交易实现方法,设计了绿色电力交易智能合约及基于简化代理拜占庭容错(SDBFT)的绿色电力交易共识过程,实现了可信自治的多微网间绿色电力交易。仿真算例验证了文中机制及模型的有效性。
Green electricity trading is an important measure to clarify the“green property”of renewable energy and encourage the low-carbon energy transition.At present,the accommodation of distributed renewable energy in microgrids still mainly relies on the principle of“the electricity generated by it is provided for itself first and the left is integrated to the grid”,but it neither quantifies the“green property”of distributed renewable energy reasonably nor fully considers the requirement and potential for the green electricity accommodation on the demand side.To this end,a trustworthy and autonomous electricity trading method among multiple microgrids considering the“green property”is proposed.First,a green electricity trading mechanism among microgrids is established to guide the rational allocation of green electricity resources by means of trading.Then,a rolling clearing and settlement method for the green electricity trading among microgrids based on Nash bargaining is proposed to guarantee the optimality of the resource allocation of green electricity trading and the fairness of the market dividend distribution.Finally,an implementation method for the green electricity trading based on a consortium blockchain is established,and a smart contract of green electricity trading and a consensus process of the green electricity trading based on the simplified delegated Byzantine fault tolerance(SDBFT)are designed.The proposed method enables the trustworthy and autonomous green electricity trading among multiple microgrids.Simulation examples verify the effectiveness of the proposed mechanism and model.
