AI Technical Summary

Technical Problem

Existing methods for optimizing the utilization rate of new energy sources are unable to distinguish between releaseable short-term peak output and continuous cumulative output that should be compressed while meeting the carrying capacity constraints, leading to problems such as reduced utilization rate of new energy sources or subsequent exceeding of carrying capacity limits.

Method used

A mechanism with decay memory for carrying residual sequence and recovery window is introduced to distinguish and retain recoverable short-term peak output. By comparing the carrying residual sequence with the closing threshold within the preset recovery window, the mechanism can distinguish between releaseable short-term peak increments and continuous carrying cumulative increments, and optimize new energy output without reducing safety margin.

Benefits of technology

This improves the feasibility of new energy utilization and the operational stability of optimization schemes, avoiding excessive reduction in short-term absorbable electricity and subsequent over-limitation or secondary power rationing caused by single-period carrying capacity limits.

Abstract

This invention discloses a method for optimizing the utilization rate of new energy sources based on carrying capacity constraints, belonging to the field of new energy optimization technology. The method includes the following steps: determining the initial carrying capacity margin of each carrying object; generating candidate output increments based on new energy units and evaluation periods, and calculating the margin occupancy increments they create for the carrying objects; transferring the margin occupancy increments to subsequent related periods according to residual decay parameters to form a carrying capacity residual sequence; distinguishing between releasable short-term peak increments and continuous carrying capacity cumulative increments based on whether the carrying capacity residual sequence is below the closing threshold within the recovery window; retaining releasable short-term peak increments and compressing continuous carrying capacity cumulative increments according to unclosed residual amounts to generate an executable output upper limit; and outputting an optimization scheme after continuous time-period power flow verification. This invention solves the problem of excessive new energy generation restrictions, subsequent over-limitation, or secondary generation restrictions caused by existing methods by constructing a carrying capacity residual sequence of candidate output increments and performing recovery window closure discrimination.
