In order to analyse the influence of the storage power station on the regional distribution network under the background of multi-element integration, and reduce the negative impact of charging and discharging load on the power network, based on the general model of multiple integration, considering the demand response characteristics, the load model of data centre, the model of energy storage station and the model of distributed new energy are established. The whole life cycle economic benefit model of energy storage system is established considering the energy storage arbitrage income, the government electricity price subsidy income, the delay of power network upgrading and the whole life cycle cost. Based on the two-stage optimization model, a “Maximum net profit-minimum fluctuation” charging and discharging strategy model is established for the energy storage power plant under the background of multi-element integration. The objective of this method is to minimize the load fluctuation in the distribution network based on the maximum net income of the energy storage system. Finally, the simulation results show the effectiveness of the proposed method.
