基于电力现货市场出清模拟的节点电价影响因素分析

Analysis of effect factors of nodal price based on electric spot market clearing simulation

中发电改"9号文"及其配套文件下发以来,8个现货试点省份已先后启动模拟试运行工作,电力市场建设稳步推进。节点电价作为一种重要的价格机制,在现货市场建设过程中被频繁采用。节点电价受到多种因素影响,对节点电价影响因素的分析梳理是十分必要的。本文在分析南方省份节点电价影响因素的基础上,对日前市场进行模拟出清,验证系统负荷、来水情况、机组报价和线路传输容量对节点电价的影响,为市场运营机构及市场主体决策提供依据。

Since the issuance of "Document 9" of the power generation reform and its supporting documents, eight pilot provinces have started simulated trial operation successively, and the construction of electric markets is in progress. Nodal Price, as an important price mechanism, has been frequently applied in the construction of the electric spot markets. Since nodal price is affected by many factors, it is necessary to analyze and sort out the effect factors of nodal price. Based on summarizing the effect factors of nodal price in southern provinces, this paper simulates the clearing of the day-ahead market, verifies the effects from different factors, such as system load, water flow, offer prices from units, and transmission capacity on nodal price, and provides a basis for decision-making of market operation institutions and market players.
