Comprehensive optimized dispatching method of electricity generation and use integration

Abstract

The invention provides a comprehensive optimized dispatching method of electricity generation and use integration. The method includes: collecting information of an electricity generation side and anelectricity use side; respectively calculating comprehensive interaction costs and a comprehensive electricity use satisfaction degree of the electricity use side; constructing a comprehensive utilitymodel of electricity generation and use integration dispatching; considering network constraints to optimize a dispatching plan of the electricity generation side and the electricity use side; and determining the dispatching plan. According to the technical solution provided by the invention, network congestion can be effectively eliminated, utilization efficiency of a generator set is also improved, a unit electricity generation cost of the electricity generation side is effectively reduced, dispatching potential of flexible loads is fully exploited at the same time, excessive fluctuation ofan electricity price in a dispatching process is restrained, and minimization of a comprehensive dispatching cost is realized.

Description

technical field [0001] The invention relates to a scheduling method, in particular to a comprehensive optimization scheduling method for the integration of power generation and utilization. Background technique [0002] With the establishment of the power market mechanism, market participants are pursuing the maximization of their own interests, which inevitably leads to network congestion in the lines around the lower-priced power plants in the system. In the traditional grid environment, the load is generally reduced according to the sensitivity to eliminate network congestion. In the smart grid environment, with the improvement of the "source-network-load" interaction capability, the participation of flexible loads in grid scheduling is economical and efficient for solving network congestion problems. [0003] As a supplement to power generation dispatching, flexible load dispatching can cut peaks and fill valleys, balance intermittent energy fluctuations, and provide aux...

AI Technical Summary

Problems solved by technology

Some regions in the initial stage of market development lack complete market operation rules and electricity price formation mechanisms. At present, they cannot adjust market supply and demand in a timely and effective manner through economic means, and the existing network congestion problems cannot be perfectly resolved.
