摘　　要：新能源的零边际成本和间歇性出力为传统节点边际电价模型带来了新的挑战。“双随机”,特别是新能源供给的随机性会导致现货市场价格波动大,无法为市场参与者带来正确的价格信号。针对高比例新能源系统,提出了一种基于连续节点边际电价(continuous locational marginal pricing, CLMP)的出清机制的市场模型。首先计及了电力系统、储能系统和数据中心的运行约束,利用CLMP的定价机理构建了高比例新能源系统能量定价模型。然后考虑了发电机组与储能系统、数据中心提供运行灵活性爬坡服务,建立了高比例新能源电力系统能量-灵活爬坡市场协同定价模型。最后,算例测试定量分析了新能源渗透率与储能对系统电价的影响,量化了储能和数据中心的运行灵活性。To achieve carbon peaking and neutrality,it is inevitable for the new energy to gain an increasing popularity in the power system.The zero marginal cost and intermittent output of new energy pose new challenges to the traditional node marginal electricity price model.“Double randomness”,especially the randomness of new energy supply,can cause wide fluctuations in spot market prices,unable to bring the correct price signal to market participants.Meanwhile,the intermittency and volatility of renewable energy generation exert tremendous pressure to the safe operation of the power system,making the lack of flexibility more prominent.Currently,China’s flexible regulation mainly relies on traditional generation-side resources,but it is costly.Therefore,mobilizing the flexibility resource capabilities of the distribution and demand side has become a new way to address the problem.This paper proposes a market model based on continuous locational marginal pricing(CLMP)clearing mechanism for high-proportion new energy systems.First,with the consideration of the operating constraints of the power system,energy storage system and data center,a CLMP-based pricing mechanism is designed for the renewable-dominant power system.Then,in consideration of the generator set,energy storage system and data center to provide operational flexibility climbing services,an energy-flexible climbing market collaborative pricing model is built.Finally,numerical tests quantitatively analyze the impact of new energy penetration rate and energy storage on system prices and quantify the operating flexibility of energy storage and data centers.
