Description
Summary:Integrated Energy Systems (Integrated Energy System, IES) to pluripotent and complementary energy ladder as the core, will greatly improve the system's energy efficiency, to achieve a variety of complementary energy flow optimization. By establishing a cold-heat-electricity integrated energy system, taking the lowest total operating cost of the system as the objective function, considering the equipment model constraints and power balance constraints, the day-to-day load simulation is used to optimize the economic operation of the integrated energy system; at the same time, the system operates in winter and summer. The operating conditions vary greatly, and the quarterly adjustment operation mode is adopted, and the branch and bound (BaB) algorithm is used to solve the optimization model. The simulation results show that the energy supply of the system is balanced, the "source-charge-storage" complementarity is strong, the system operates flexibly, cost-effectively, and at the same time, the system emits less polluting gas, which is beneficial to environmental protection.
