Optimization model of Multi-energy system based on multi-source energy storage

Aiming at the problem of renewable energy fluctuations in the multi-energy system and the coordination of the energy output of electric, heating and gas, based on the supply characteristics of renewable energy and the storage characteristics of energy storage facilities, a multi-energy system optimized operation model based on multi-source energy storage is established. An optimization model for coordinating and balancing the volatility of renewable energy using heat and gas storage facilities has been established. First, a multi-energy system based on multi-source energy storage (MESBMSES) is proposed. The system is divided into three parts: the supply side, the energy conversion unit and the load side. Then, on this basis, a MESBMSES optimal scheduling model based on economic optimization was established. Finally, taking a region in Northeast China as an example, based on the output data of renewable energy, the storage of energy storage facilities is analyzed. The simulation results show that the energy input and output of energy storage facilities and the coordinated optimization model of renewable energy output proposed in this paper have good operating economy and large-scale utilization of renewable energy
