Load source coordinated control rolling correction method for absorbing new energy interception power

Abstract

The invention discloses a load source coordinated control rolling correction method for absorbing new energy interception power. The load source coordinated control rolling correction method mainly comprises the following steps: according to the adjusting capability of each virtual high-energy load, acquiring the adjusting amount of each virtual high-energy load and the intraday rolling correction adjusting amount of a renewable energy source by establishing a mathematical model with the minimum wind-abandoning and light-abandoning amount as an objective, correcting a day-ahead scheduling plane, and providing a reference for a power grid to make an intraday scheduling plane for the new energy and the virtual high-energy load. The load source coordinated control rolling correction method has the advantages as follows: a dilemma that in the prior art, peak shaving is carried out solely by the conventional energy source is overcome; large-scale new energy absorption is achieved; resource waste is reduced; safe and stable operation of the power grid is achieved.

Description

technical field [0001] The present invention relates to the technical field of renewable energy utilization and dispatching, and in particular, to a rolling correction method for coordinated control of charge sources to accommodate blocked power of new energy sources. Background technique [0002] With the rapid development of renewable energy, new energy such as wind and solar power has attracted more and more attention due to its advantages of huge reserves, renewable, wide distribution, and no pollution. But at the same time, due to the intermittent, fluctuating, and random characteristics of wind and solar power, it is difficult to effectively cope with the regulation ability of conventional power sources, which increases the difficulty of power grid dispatching and control. In order to ensure the safe and stable operation of the power grid, some grid-connected wind and solar power units have to be removed, and even the built wind and light power plants have been abandon...

But at the same time, due to the intermittent, fluctuating, and random characteristics of wind and solar power, it is difficult to effectively cope with the regulation ability of conventional power sources, which increases the difficulty of power grid dispatching and control.

In order to ensure the safe and stable operation of the power grid, part of the grid-connected wind and solar power units had to be cut off, which even led to the abandonment of wind and light in the completed wind and light power plants, resulting in a huge waste of resources
