Research on Shared Energy Storage Cooperative Voltage Regulation Strategy Based on Energy Interconnection Mode

Aiming at the node voltage overrun problem caused by the high proportion of new energy sources connected to the power system, this paper uses shared energy storage to carry out charging and discharging operations according to the demand to realize the voltage regulation control of the node loads as well as the balance and optimization of the system. This paper proposes a collaborative scheduling optimization strategy for shared energy storage based on the energy interconnection model, establishes a mathematical model of voltage overrun with economic efficiency as the core objective, and determines the optimal energy storage output size and time sequence using an improved particle swarm algorithm to achieve collaborative control of different devices. It promotes the establishment of an energy information sharing model for energy storage equipment, realizes capacity sharing, resource integration, system reliability improvement, and promotes the popularization and sustainable development of clean energy.
