With the large-scale grid integration of renewable energy sources, distributed power sources are difficult to meet the black start requirements due to low inertia and small capacity. For this reason, this paper investigates the black start of distributed renewable energy units and small hydropower units with cooperative participation. Based on the frequency response model, we study the black start strategy of power system considering virtual synchronization control. Simulations based on the IEEE14 node system show that: small hydropower units and renewable energy units cooperatively participate in the black-start process with stable frequency response and meets the security requirements.
