Embodiment 1

[0067] A method for analyzing and optimizing the investment scale of a power grid is carried out sequentially in accordance with the following steps:

[0068] Step 1. In accordance with the "Pilot Program for the Reform of Power Transmission and Distribution Prices in Shenzhen" issued in November 2014 and the "Measures for the Supervision and Examination of Power Transmission and Distribution Pricing Costs (Trial)" issued in June 2015 (hereinafter referred to as the "Pilot Program"), ""Measures""), according to the set grid investment scale and power generation, establish an analysis model for the impact of grid investment scale on transmission and distribution prices, that is, the transmission and distribution price calculation model. Among them, the basic formulas for calculating transmission and distribution prices are: ① transmission and distribution prices = Allowed income ÷ Transmission and distribution electricity, ② Allowed income = Allowed cost + Allowed income + Tax, ...

Abstract

The invention relates to a method for analyzing and optimizing the grid investment scale. The method comprises the steps of firstly building a transmission and distribution price calculation model according to the set grid investment scale and the amount of power, then building a sensitivity analysis model and a multi-scheme simulation analysis model on the basis of the transmission and distribution price calculation model, then building an investment optimization model on the basis of the sensitivity analysis model and the multi-scale simulation analysis model, and finally determining the reasonable grid investment scale. The design can achieve scientific, rational and effective optimization for the grid investment scale.

Description

technical field [0001] The invention belongs to the technical field of electric power system planning, and specifically relates to a method for sub-optimizing the investment scale of a power grid to meet the new requirements of power transmission and distribution price reform and realize scientific, reasonable and effective optimization of the investment scale of the power grid. Background technique [0002] On November 4, 2014, the National Development and Reform Commission issued the "Notice on the Pilot Reform of Power Transmission and Distribution Prices in Shenzhen", which marked the official launch of my country's power transmission and distribution price reform. In April 2015, the National Development and Reform Commission issued a document clearly including the four provinces of Hubei, Anhui, Ningxia, and Yunnan into a new batch of pilot reforms of transmission and distribution prices, and officially approved and approved the 2016-2018 transmission and distribution pr...
