Abstract

The invention discloses a power grid planning scheme evaluation and optimization method and system based on full-cost electricity price, and the method comprises the steps: obtaining the basic data ofa power grid, and calculating the node marginal power generation cost, the node unit load power construction cost, and the node unit load power operation and maintenance cost according to the basic data of the power grid; linearly adding the node marginal power generation cost, the node unit load power construction cost and the node unit load power operation and maintenance cost to generate a power grid full-cost electricity price; establishing a power grid planning evaluation index system according to the full-cost electricity price of the power grid; and assessing the plurality of power grid line planning schemes according to the power grid planning assessment index system, and optimally selecting an optimal power grid planning scheme. The method can comprehensively evaluate the safetyand economy of a power grid planning scheme, is beneficial to improving the lean level of power grid planning, and can provide a quantitative analysis method and an auxiliary decision-making tool forinvestment planning of a power grid company under the background of new power transformation.

Description

technical field [0001] The invention relates to the technical field of grid planning, in particular to a method and system for evaluating and optimizing grid planning schemes based on full-cost electricity prices. Background technique [0002] Power grid planning is based on load forecasting and power supply planning to determine when and where to invest and build what type of transmission lines and the number of circuits to achieve the required transmission capacity within the planning cycle and meet various technical indicators. Optimizing grid planning investment under the premise. [0003] The quality of the power grid planning scheme plays a key role in the security, stability and economic operation of the power grid. At present, the evaluation methods of power grid planning schemes mainly analyze and compare alternative schemes from the aspects of safety and reliability, but do not pay enough attention to the economics of power grid planning schemes, especially the la...
