Integrated wind storage system, namely the wind power generation equipped with energy storage, has a black-start capability, which can be controlled to use the system as a black-start power source. On this basis, a black start program for the integrated wind storage system is developed based on a single wind turbine. Firstly, the energy storage device is started through grid-forming control, and to avoid the self-excitation generated by excitation inrush or resonance in the process of transformer input, the inertia link is added based on the original voltage-loop control to realize soft-start strategy. Then, the energy storage system establishes the AC frequency and voltage to realize restoration of the wind turbine generators and the loads. After the wind-storage integrated system is stably started, the electrical energy is transmitted to the 35 kV busbar through the main transformer and transmission line, to complete the black start process. Finally, a simulation model of the integrated wind-storage system is built on the PSCAD/EMTDC platform to validate the black-start scheme using the soft-start strategy, which keeps the voltage stable and the power balanced, and completes the start-up of the system, and at the same time suppresses the excitation inrush current effectively.
