So that the wind storage black start can smoothly operate. The tracking control layer control is an optimized control strategy for a single energy storage power station. To ensure stable voltage and frequency in the black-start, the core energy storage is controlled by V/f, and the remaining energy storage is controlled by PQ.
When all energy storage power stations are in stable operation, it can ensure the balance between effective output power of ESSs, actual power of wind power cluster and power of black-start load. So that the wind storage black start can smoothly operate.
Thus, offshore wind farms (OWFs) may need to provide advanced grid services such as black start, until now provided by conventional power plants. To become new black-start sources, OWFs may use a self-start unit, in the form of a grid-forming converter and additional energy storage to enhance availability despite adverse wind conditions.
The multiple energy storage state has been formed. Therefore, in order to ensure the successful implementation of black-start, multiple energy storage power stations instead of one are usually adopted to participate in the black-start .
Aiming at the problem that wind power and energy storage systems with decentralized and independent control cannot guarantee the stable operation of the black-start and making the best of power relaxation of ESSs, a coordinated control strategy of multi-energy storage supporting black-start based on dynamic power distribution is proposed.
This has increased the risk of wide-area blackouts. Thus, the changing generation profile in the power system necessitates the use of alternate sources of energy such as wind power plants, to provide black-start services in the future. However, this requires grid-forming and not the traditionally prevalent grid-following wind turbines.
