摘要
立足于我国多层次市场体系建设现状和国、网、省三级调度业务架构,界定现阶段区域内省间市场和跨区省间市场在全国统一电力市场中的功能定位。为了解决不同范围、不同周期市场的衔接问题,提出建设长三角D-2日电能量市场,通过D-2日电能量市场统筹全网电力电量平衡,保障区外送电计划的可执行性,实现市场从中长期到日前的平滑过渡。引入市场用户报量报价参与区域市场;设计市场衔接、市场定价、偏差处理等关键机制;考虑到华东电网是耦合关系复杂的交流电网,构建全网络出清模型。算例结果表明,D-2日电能量市场有利于全网资源优化配置,保障全网电力安全以及解决发电侧市场力问题,证明了市场机制设计的有效性。
Based on the current situation of China’s multi-level market system construction and the threelevel dispatch business structure of the state,network and province,the functional positioning of the regional inter-provincial market and inter-regional inter-provincial market in the national unified electricity market at the current stage is clarified.In order to solve the articulation problem of markets with different ranges and cycles,the construction of D-2 day electric energy market of Yangtze River Delta is proposed,the power and energy of the entire network power is balanced through the D-2 day electric energy market,ensuring the execution of the out-of-region power delivery plan and realizing the smooth transition of the market from medium-and long-term to day ahead.It is introduced that the customers participate in the regional market by quotation.The key mechanisms such as market convergence,market pricing and deviation handling are designed.Considering that the East China Power Grid is an AC grid with complex coupling relationships,an entire network clearing model is constructed.The example results show that the D-2 day electric energy market is conducive to the optimal allocation of entire network resources,ensure entire network power secu⁃rity and solve the market power problem at the generation side,which proves the effectiveness of the market mechanism design.
