Multi-Objective Optimal Dispatch of Integrated Energy System Considering Flexible Loads

The Integrated Energy System (IES) of industrial parks involves unified planning and dispatch operation of multiple energy sources including electricity, gas, and heat. Firstly, a typical energy supply structure for the park's integrated energy system was established, and a PIES mathematical model with flexible loads that can be shifted/transferred/reduced was constructed based on analysis of its demand characteristics. Secondly, a multi-objective optimization operation model was proposed that coordinately considers economic efficiency, environmental protection, and energy efficiency. Finally, the Multi-Objective Grey Wolf Optimization Algorithm (MOGWO) was introduced to solve the model, verifying MOGWO's effectiveness in handling complex nonlinear optimization problems of PIES, thus providing a more comprehensive solution for efficient operation of low-carbon PIES.
