Multi-source coordinated peak regulation method for spatial distribution and regulation capability constraints of various types of power supplies

Abstract

The invention discloses a multi-source coordinated peak regulation method for spatial distribution and regulation capability constraints of various types of power supplies. The method comprises the steps of S1, carrying out reasonable clustering of other power supplies of a main network in a region A and a region B through employing an aggregation clustering method, and obtaining a clustering result and a clustering number NQ. According to the invention, the peak regulation problem of the power grid A is divided into two sub-problems of a power grid B and a main grid A. According to the distribution condition of other power supply units of the power grid A, firstly, by controlling power output of an aggregation group of the region B, on the basis of meeting the local load and the outgoingpower of the region B, the power of the B-to-main grid power is optimized and scheduled, the fluctuation characteristic of the outgoing power is improved; then for the area of the main grid A, after analyzing the equivalent load after receiving the outgoing power of the region B, the peak regulation task borne by each aggregated power supply group of the main grid A is determined in sequence according to the peak regulation potential sequence of each aggregated group, and finally the peak regulation task is issued to each unit to obtain the day-ahead unit output plan of the power grid A, so that the peak regulation pressure of the power grid A is effectively relieved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a multi-source coordinated peak-shaving method for various types of power supply space distribution and regulation capacity constraints. Background technique [0002] The peak-shaving unit is used to adjust the peak of the load. The power generation and transmission of the power system are carried out at the same time, and the power load changes with time, so the power generated will change with the change of power consumption. In this way to maintain a balance, generally speaking, the power plant responsible for peak regulation is a hydroelectric power plant, because the hydroelectric unit starts up quickly, and the load can be increased or decreased only by adjusting the guide vanes, while thermal or nuclear power plants are very suitable for peak regulation. If it is uneconomical, the combustion efficiency of fuel will be reduced, and the short-term load of nuclear power units wi...
