In order to solve the problem of grid voltage fluctuations in multi-energy systems. This paper proposes a coordinated optimization control method based on battery electric storage, heat storage, and gas storage. Firstly, analyzing the different operating modes of electricity, heat, and gas in the system. Establish a coupling model of the energy system when the multi-energy storage is connected. Secondly. According to the energy storage characteristics of distributed energy storage, by study of the influence mechanism of the battery electric storage , gas storage , heat storage on the voltage stability of the power grid. Established a cooperative optimization model of distributed energy storage. Take the minimum voltage fluctuation as the optimization goal. Under the premise of satisfying the constraints of distributed energy storage. Combined with the real-time charging and discharging state of each distributed energy storage system, Using particle swarm optimization method to maintain voltage stability of nodes. Finally, take a regional multi-energy system as an example to simulate, It is verified that the proposed cooperative optimization control method can effectively improve the voltage stability of the power grid
