Abstract
With the advancement of energy structure transformation and electricity market reform, power systems are confronted with challenges such as supply-demand balance and renewable energy accommodation. To enhance the flexibility and economic efficiency of power systems, this study focuses on load optimization management based on demand response, aiming to achieve effective allocation of power resources through rational demand-side management. A multi-ob jective optimization model that considers user comfort, electricity cost, and grid operational safety is constructed, and an improved particle swarm optimization algorithm is employed to solve for the optimal load scheduling scheme. The model incorporates time-of-use pricing mechanisms and user participation incentive measures to fully mobilize user responsiveness. Simulation analysis using data from an actual regional power grid demonstrates that the proposed method can effectively reduce peak load by approximately 15% and decrease system operating costs by about 10%, while significantly enhancing renewable energy accommodation capacity, all under the premise of ensuring user satisfaction. The research findings indicate that load optimization management based on demand response is an effective approach to addressing supply-demand conflicts in power systems and promoting clean energy accommodation, providing new ideas and technical support for achieving energy conservation and emission reduction and improving power system operational efficiency in the context of electricity markets, which holds significant theoretical and practical value.
