Power system whole process recovery optimization method based on subject importance dynamic evaluation

Abstract

The invention provides a power system whole-process recovery optimization method based on main body importance dynamic evaluation, and the method comprises the steps: determining the global recovery state of each recovery main body under an mth step length through the following mode: determining the overall recovery state of each recovery main body under the mth step length based on the source load power, the flexibility resource balance degree and the energy storage charge state of a recovered power system under the (m-1) th step length, determining the importance value of each recovery subject in the current step length; determining the wind power output and the fluctuation power thereof on the optimization time domain of the current step length; solving the recovery income objective function to obtain (m-k + 1) step lengths and a local recovery state of each recovery subject corresponding to each step length; and taking the (m-k + 1) step lengths and the local recovery state of each recovery main body under the first step length in the local recovery states of the recovery main bodies corresponding to each step length as the global recovery state of each recovery main body under the mth step length so as to improve the recovery efficiency of the power system.
