Abstract

The invention relates to the technical field of new energy grid connection and control, particularly provides a post-evaluation method and device for a new energy consumption increase amount, which aim to solve the technical problem that the new energy consumption increase amount is difficult to accurately quantify and evaluate. According to the method, starting and operation strategies of a power supply and a power grid when no measures are taken are learned by using a time sequence operation optimization model, and then the new energy consumption amount of the power grid when no measures are taken is simulated and calculated based on a given boundary condition, so that accurate quantitative evaluation of the new energy consumption improvement amount is realized.

Description

technical field [0001] The invention relates to the field of new energy grid connection and control, in particular to a post-evaluation method and device for new energy consumption and promotion. Background technique [0002] With the proposal of the "double carbon" goal, the installed capacity of new energy during the "14th Five-Year Plan" period will continue to maintain a rapid growth trend. It is expected that in 2030, a high proportion of new energy power systems will generally form in many places. The continuous increase in the proportion of new energy installed capacity will bring huge pressure on the new energy consumption of the power grid. In order to realize the efficient consumption of new energy, power grids in many places have also actively promoted the flexible transformation of thermal power units, the complementary operation of multiple types of power sources, the enhancement of power grid transmission capacity, the increase of new energy installed capacity ...
