Control strategy of optical storage combined power generation system for black start

In recent years, with the increasingly complex structure and control of power grid, in order to limit the impact of power outage accidents on the power system, it is necessary to study the decision-making method of black start scheme after power outage, and obtain a restoration scheme that is safe and reliable and can quickly restore power supply. The main contents of this paper are as follows: First, the output control method of photovoltaic power station based on sliding mode control is proposed, so that the photovoltaic power station can realize the load tracking more accurately and more quickly. Secondly, a control strategy combining MPPT control and load tracking control is proposed. Finally, based on the control strategy, a black start scheme of energy storage photovoltaic power station is proposed, and a simulation model is built in SIMULINK to determine the black start scheme and verify its feasibility.
