Abstract：In the distribution network of the new power system，due to the access of a large number of new

energy power generation devices，the power supply side output of the distribution network becomes unstable and

loses control ability. In order to deal with a series of problems such as the difficulty of photovoltaic consumption，

an operation optimization framework of shared energy storage system in distribution station area was proposed，

which aims to minimize the overall operation cost of energy storage power station and improve economic benefits.

This framework took into account the time-of-use price and technical constraints such as battery capacity and

charge-discharge efficiency，and an optimized operation control strategy was developed. The numerical simulation

results show that this strategy not only improves the economy of the shared energy storage system，but also

promotes the sustainable development of the entire power network.
