Operation optimization of multi-region integrated energy system including cool-heat-electricity cogeneration and energy storage equipment

Integrated energy system (IES) is a key technology to improve social energy utilization efficiency and achieve sustainable development. It is an important research direction for multi-region IES operation optimization to carry out collaborative optimization of each region according to load characteristics. In this paper, the mixed integer linear optimization model of multi-region IES optimization including cool-heat-electricity cogeneration and energy storage equipment was established, areas interact through the heat grid and the volatility of renewable energy was simulated by scenario analysis method. The Yalmip toolbox and Cplex commercial software were used for optimization calculation in matlab. The results show that the multi-region optimal operation considering the uncertainty of wind power can realize the coordinated distribution of thermal energy, improve the energy utilization of the system, and the energy storage equipment can decouple the thermoelectric connection to improve the system operation economy.
