Orderly Power Utilization Based on a Full-Cycle-Variable-Intervals Optimization Algorithm

Abstract

This year, extremely hot weather in China has caused a hydropower shortage in the southwest and an increased load in the east, thus placing great pressure on the system. Orderly power utilization (OPU) is the most efficient means to address severe short-term power shortage so as to avoid cycled blackout events. However, the traditional OPU strategy usually ignores Openness, Equity and Justness (OEJ) principles which may inconvenience many end users (especially big industrial users) and affect satisfaction. Herein, an optimization framework for full cycle OPU is proposed. According to the demand difference in OPU plans in different periods, the optimization model of a full cycle OPU plan with variable intervals is established. Numerical simulation results indicate the great potential of the proposed method to solve power shortage problems by considering the OEJ principles.
