适应高水电占比的电力现货市场机制设计与实践

不同于中国其他水电规模占比较小的电力体制改革综合试点电网,中国四川电网存在水电装机占比高、丰枯水期发电原则差异大、网架复杂约束多、发电调度策略分散等独有特点,故设计丰枯双期的市场机制以适应四川丰枯水期电力供需形势及电网运行特性差异.首先,从市场设计思路、市场总体模式、丰枯水期电力现货市场等角度说明四川电力现货市场机制;...

Design and Practice of Electricity Spot Market Mechanism Adapting to Characteristics of High Proportional Hydropower

In China, different from other comprehensive pilot grids of power system reform with relatively small scale of hydropower, Sichuan power grid has some unique characteristics, such as high proportion of hydropower installed capacity, large difference in power generation principles between high-water and low-water periods, complex grid structure constraints and decentralized power generation dispatching strategy. Therefore, the high-water and low-water market mechanism is designed to adapt to the grid supply and demand situation and the difference of power grid operation characteristics between high-water and low-water periods. Firstly, this paper explains the electricity spot market mechanism in Sichuan Province from the perspectives of market design ideas, the overall market model, and the high-water and low-water electricity spot markets. Then on this basis, the functional structure adapted to the spot market mechanism in Sichuan Province is proposed, and its own characteristics in the aspects of high-water and low-water period market models, physical space for market operation, hydropower coupling constraints, and optimization clearing process are analyzed. Finally, some suggestions are put forward according to the operation practice of high-water and low water electricity spot markets in Sichuan Province of China.
