新能源电力系统能量-灵活爬坡市场定价研究
Research on energy-flexible climbing market pricing for new energy power systems
摘要
Abstract
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.关键词
