电力现货市场环境下提供位置信号电价机制的协同作用

对电价中的位置信号及能够提供位置信号的电价机制进行分类梳理和总结，对电力现货市场环境下电价中位置信号的作用进行分析；结合电力现货市场仿真，定量分析在不同的电网结构及系统阻塞条件下，电能量现货市场中的“节点边际电价（LMP）机制”和“分区输电定价”机制在实现其作为公共事业服务价格作用方面的协同作用关系；结合中国某省电网的实际情况，通过电力现货市场仿真和电价测算对分析结果进行验证，为中国电力现货市场环境下的电价机制选择提出建议。

Coordination Functions of Electricity Price Providing Locational Signals under the Circumstance of Electricity Spot Market

The paper investigates the locational signals of the electricity prices and the pricing mechanisms which can provide locational signals, and analyzes the functions of locational signals of electricity prices under the circumstance of electricity spot market. Based on simulation of electricity spot market, the paper quantitatively analyzes the coordination functions of location marginal pricing (LMP) mechanism and zonal transmission pricing mechanism in realizing their pricing role as public utilities under different network structures and system congestion conditions. According to the actual conditions of a provincial power grid in China, a case study was carried out to verify the analysis results through transmission price calculation and electricity spot market simulation. Suggestions are provided for selection of electricity pricing mechanism under the circumstance of electricity spot market in China.
