Embodiment 1

[0108] A method for analyzing and optimizing the investment scale of a power grid. The method performs forecast analysis and optimization on the investment scale of a certain power grid enterprise in 2009, and includes the following steps in sequence:

[0109] Step 1: Establish an analysis and prediction model of the influence of grid investment on the operation of grid enterprises, wherein the analysis and prediction model includes a cost prediction unit, a power transmission and distribution revenue forecast unit, a profit forecast unit, a fund source and utilization forecast unit, and an asset-liability forecast unit , the cost forecasting unit includes a wage and social insurance fee forecasting module, a depreciation fee forecasting module, a repair fee forecasting module, a commissioned operation and maintenance fee forecasting module, and other cost forecasting modules, and the power transmission and distribution revenue forecasting unit includes a power distribution pric...

Embodiment 2

[0117] Step is with embodiment 1, and difference is:

[0118] Step 2:

[0119] Follow the steps below to conduct multi-scenario forward simulation analysis:

[0120] a. Set different electricity prices, electricity and grid investment in 2009 and combine them into multiple simulation schemes;

[0121] b. First set different investment scales in each simulation plan, and then simulate and calculate the total profit and asset-liability ratio of the enterprise in 2009 through the analysis and prediction model;

[0122] c. After comparing and analyzing the calculated total profit and asset-liability ratio, determine the reasonable investment scale of the power grid enterprise in 2009.

[0123] In order to verify the effectiveness of the inventive method, the predicted value of the grid enterprise's main operating indicators in 2009 obtained by the inventive method is compared with the expected completion value of the grid enterprise's operating indicators in November, 2009, and ...

Abstract

The invention relates to a method for analyzing and optimizing an electric grid investment scale. The method comprises the steps that firstly, an analyzing and predicting model for the influences of electric grid investment on the operation of an electric grid enterprise is established; secondly, a plurality of modeling schemes are formed by combining different set electricity prices, electricity quantities and electric grid investments in a prediction period; thirdly, each modeling scheme is substituted into the established analyzing and predicting model to calculate the total profit and the asset-liability ratio of the enterprise in the prediction period in an analog mode; finally, the total profits obtained through analog calculation and the asset-liability ratios obtained through analog calculation are compared and analyzed to determine the reasonable investment scale. By means of the design, the electric grid investment scale can be reasonably and effectively optimized.

Description

technical field [0001] The invention belongs to the technical field of power system planning, and in particular relates to a method for analyzing and optimizing the investment scale of a power grid, which is suitable for realizing scientific, reasonable and effective optimization of the investment scale of the power grid. Background technique [0002] In order to meet the growing demand for electricity in various industries and people's lives, grid companies need to formulate corresponding grid development plans to promote moderately advanced development of the grid. The long investment cycle of power grid construction will not only affect the current economic activities of power grid enterprises, but also have a significant impact on the future economic benefits, financing needs and financial status of enterprises. If the investment in the power grid is too small, the development speed of the power grid cannot meet the needs of economic and social development, which may cau...
