基于综合电价的配电网日前互动模式与模拟

配电侧电力市场的建立需要依托配电网内各类资源和电网的友好互动,因而需要科学的激励机制来引导。为此,文中提出了激励配电侧用户与电网日前互动的模式。依据激励相容原理,提出了一种合理有效的电价机制,厘清了配电网内弹性用户对容量节约效益的贡献;依托输电侧日前市场,设计了用户参与配电侧日前互动的架构、过程及结算;基于分散决策思想,模拟了配电网用户自主响应、多轮博弈的日前互动模型。算例表明,文中所述机制能公平分摊互动产生的成本和效益,深度激励用户与配电网的友好互动,促进配电网有效资产利用率的提升,实现配电网与微电网协同运行、互利共赢。

Day-ahead Interaction Mode and Simulation in Distribution Network Based on Composite Price

The establishment of distribution market needs to rely on the friendly interaction between various resources and power grid in the distribution network. Hence their demand for guidance by a scientific incentive mechanism. To this end, a mode is proposed for encouraging distribution side users interacting with the grid. According to the principle of incentive compatibility, a reasonable and effective price mechanism is suggested to clarify the contribution of flexible users to capacity saving. Relying on the transmission day-ahead market, the participation of users in distribution day-ahead interaction is designed including architecture, process and settlement. Based on the idea of decentralized decision-making, the interactive model of users'' self-response and multi-round game of distribution network is simulated. The numerical example shows that, with the proposed mechanism, the costs and benefits arising from interaction can be fairly shared to deeply inspire user interaction with the distribution system, promote effective assets utilization of the grid, and achieve cooperation and mutual benefit as a win-win situation between distribution network and microgrids.
