A two-layer coordinated operation optimization model for multi-energy complementary systems considering demand response

Abstract

Demand response is an effective way to alleviate the gap between energy supply and demand and enhance energy utilization efficiency. It is of great significance to promote the sustainable development of multi-energy complementary systems. Firstly, a demand response model based on demand elasticity matrix is constructed for a multi-energy complementary system. With the consideration of uncertainty of clean energy output, a two-level coordinated operation optimization model of the multi-energy complementary system is constructed, where the upper layer considers the overall benefit of the multi-energy complementary system, and the lower layer focuses on the benefit of the internal generation side. A two-stage solution algorithm composed of "clean energy uncertainty processing - optimization model processing based on genetic algorithm" was adopted to carry out multi-scenario simulation example analysis.
