Supply-demand balance analysis method and supply-demand balance analysis system based on electric power, electric quantity and peak regulation balance

Abstract

The invention provides a supply-demand balance analysis method and a supply-demand balance analysis system based on electric power, electric quantity and peak regulation balance. The supply-demand balance analysis method comprises the steps of acquiring an electric power demand analyzing and prediction result, an electric power supply analyzing and prediction result, electric power and electric quantity exchange data and network loss of each month; determining an electric power balance surplus according to a preset electric power balance calculating model; determining the number of a coal combustion set working hours according to a preset electric quantity balance calculation model; determining the peak regulation profit or loss according to the preset electric power balance calculating model; and determining whether electric power supply-demand balance is realized according to the electric power balance surplus, the number of the coal combustion set working hours and the peak regulation profit or loss. The supply-demand balance analysis method and the supply-demand balance analysis system provided by an embodiment of the invention can comprehensively and thoroughly analyze supply-demand balance of an electric power market and therefore have advantages of improving accuracy of supply-demand balance analysis result of the electric power market, facilitating reasonable making for short-period plan and middle-term plan of the electric power market, facilitating reasonable adding or reduction for installed capability of the coal combustion set, and preventing resource wastage.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a supply-demand balance analysis method and system based on power, electricity and peak-shaving balance. Background technique [0002] The supply and demand relationship in the electricity market is an important part of the electricity market mechanism and plays a fundamental role in the allocation of electricity resources. In the electricity market, the relationship between supply and demand determines the direction and intensity of price regulation for the smooth flow and optimal allocation of various power resources, and promotes the effective growth of power company capital and the increasing quality of life and satisfaction of electricity customers, thereby Make the electricity market more prosperous. During peak power consumption in winter and summer, the supply of electric energy is often in short supply, resulting in the need to take extreme measures to control power...

AI Technical Summary

Problems solved by technology

[0003] In the past, the supply and demand balance analysis of the power market was basically to study the power balance, mainly whether the demand and supply forecast of the whole society were in balance, or whether the power generation and purchase power (plus network loss) were in balance. Analysis of the balance cannot fully reflect the supply and demand balance of the power grid, which will easily lead to one-sidedness and inaccuracy of the obtained supply and demand balance analysis results
