Multi-energy power generation optimization scheduling method considering active participation of nuclear power in peak regulation

Abstract

The invention provides a multi-energy power generation optimization scheduling method considering active participation of nuclear power in peak regulation. The method comprises the steps of obtaining pre-power consumption of a load in each time period according to average power consumption of a previous week and pre-power consumption reported by each main power consumption department based on an incentive policy; obtaining pre-generating capacity of wind and light according to the prediction means; determining a scheduling direction according to the relation comparison between the determined day-ahead pre-electricity consumption and the pre-electricity generation amount of wind and light, and distributing the pre-electricity generation amount of wind, light and nuclear fire by taking the optimal economic cost of electricity generation as a target; a multi-dimensional three-dimensional domain is constructed, a comprehensive energy dispatching boundary is determined, and when wind and light output fluctuation or load fluctuation is coped, the nuclear fire generating capacity is adjusted in time, and the generating cost is reduced; and scheduling the comprehensive energy by using the constructed multi-dimensional three-dimensional domain to obtain a power generation scene with the optimal cost. The overall cost of comprehensive energy power generation is reduced, the peak regulation pressure of a power grid is reduced in a novel power system, the calculation time of the system is shortened when dispatching operation is implemented, and the dispatching flexibility is enhanced.

Description

technical field [0001] The invention relates to the technical field of scheduling of power generation terminals in power systems, in particular to a multi-energy generation optimization scheduling method that takes into account nuclear power's active participation in peak regulation. Background technique [0002] Large-scale wind power grid integration has led to a sharp increase in system flexibility requirements, and the replacement of some conventional power sources by wind power and other renewable energy sources has further reduced the system's flexible power sources. At present, most of the research on system flexibility is based on principle analysis and qualitative evaluation, and insufficient consideration is given to the supply and demand relationship of system flexibility and the coordination and optimization of flexible resources such as source, load and storage. The high proportion of renewable energy access makes it necessary to improve the peak-shaving capabil...

Problems solved by technology

The increase in the proportion of new energy power generation has increased the peak-to-valley difference in the equivalent load of the system (the sum of new energy output and load), thereby increasing the peak-shaving demand of the power system; on the other hand, large-scale new energy replaces thermal power, Lack of peak-shaving capacity of the system, which seriously restricts the consumption of new energy
