Embodiment

[0081] see figure 1 , a grid investment planning method that guarantees the availability of permitted revenue, the method includes the following steps:

[0082] a. Based on the historical data and development situation of the national economy, comprehensively use the time series method, multiple linear regression method and sub-industry forecasting method to predict the maximum load of the whole society and the power consumption of the whole society in the planning year of the regional power grid;

[0083] b. Based on the regional energy production and consumption status, combined with the general situation of power supply and reserve power supply, and the planning of power transmission outside the region, the prediction results of step a are used to calculate the power balance results of the regional power grid in the planning year;

[0084] c. Use the calculation result of step b as the boundary condition, use the power system analysis comprehensive program to calculate, and...

Abstract

A method of grid investment planning guaranteeing permissible revenue availability is provided. By taking the power demand and power flow of regional power network in planning year as boundary conditions, the power system analysis integrated program is used to program the target grid structure, the investment in power network planning is estimated, so that the investment is based on the power network plan; the economic benefits corresponding to the permitted revenue model and the predicted revenue model in the whole operation period are calculated respectively; then, with the economic benefitcorresponding to the permitted income as the objective, if the economic benefit corresponding to the forecasted income is not lower than the target, it is considered that the investment in power network planning can guarantee the income of the enterprise; otherwise, the long-term project is partially reduced and the target grid structure planning is carried out again until the economic benefit corresponding to the forecasted income is not lower than the target, and the investment corresponding to the target grid structure planning is taken as the result of the power network investment planning. The planning method of this design has clear logical thinking, reliable data source and strong maneuverability, and can accurately carry out the power network investment planning calculation.

Description

technical field [0001] The invention relates to a grid investment planning method, in particular to a grid investment planning method that ensures the availability of permitted income, and is mainly suitable for accurately measuring grid planning investment. Background technique [0002] In 2014, the National Development and Reform Commission launched a pilot reform of power grid transmission and distribution prices in Shenzhen; in 2015, the reform pilot was expanded to six provincial power grids including Mengxi and Hubei; in 2016, it was further expanded to 12 provincial power grids including Beijing and Tianjin and North China regional power grid; in 2017, comprehensively promote reforms in the remaining provincial and regional power grids across the country. After the reform of electricity transmission and distribution prices, the profit model of power grid enterprises has changed from the purchase and sale price difference model to the permitted income model, and the pe...
