Dual-collaborative inertia control of photovoltaic energy storage power station

In order to solve the problem of voltage fluctuation caused by the power mismatch of the parallel operation system of photovoltaic storage in power systems, this paper proposes a new control strategy suitable for this application scenario, which is based on the tracking of the maximum output active power of the photovoltaic array, combined with the local load power information, and cooperatively controls the energy storage and photovoltaic output in the power transmission process, so as to achieve efficient and fast consumption of the photovoltaic active power in the system. Finally, the simulation model is built by MATLAB/Simulink software, and the simulation results show that the cooperative control strategy is effective.
