摘要

在新型电力系统和电力现货市场建设背景下，如何选择合理的输电价格机制，使之与电力现货市场价格形成“合力”，协同引导新能源优化选址和投资时序，在促进提高源网投资效率的同时助力新能源消纳，助力“双碳”目标的平稳、有效实现，成为新时期电价改革工作面临的热点问题之一。为此，该文在新型电力系统建设背景下输电定价的原则、功能及影响机理分析的基础上，提出与新型电力系统建设协同的输电定价机制量化评价指标，并构建基于“新能源投资时序及选址预测模型”和“基于半不变量和Gram-Charlier级数展开随机潮流计算方法的输电网投资现值评估模型”的量化指标计算方法。以我国某省电力系统简化算例为例，量化分析在无阻塞和断面阻塞系统中不同输电价格机制对终端电价水平和新能源消纳量的影响，为新型电力系统和电力现货市场建设背景下省级共用网络输电定价机制的选择提供一定理论与方法支撑。

Abstract

In the course of the construction of China's new power system and power spot market

how to choose reasonable transmission pricing mechanism to form a "synthetic force" with power spot market price becomes a key issue. The synergy is supposed to guide the new energy optimal siting and investment timing

improving the investment efficiency of the generation units and promoting the consumption of renewable energy. To this end

based on the clarified principles

functions

and impact mechanisms of transmission pricing

this article proposes quantified indexes for the electricity transmission pricing mechanism to coordinate with the construction of new power systems. We also put forward an index calculation method by "new energy investment timing and siting prediction model" and "the present value evaluation model for transmission network investment based on the stochastic power flow calculation method with semi-invariant and Gram-Charlier series expansion". Taking the simplified power system of certain province of China as an example

this paper quantitatively analyzes the impact of different transmission pricing mechanisms on the terminal electricity price level and new energy consumption in non-congestion and congestion systems. The proposed method can provide theoretical and methodological support for determining the provincial shared network transmission pricing mechanism in the context of new power system construction.
