Coordinated Control of Black Start Process Based On Hybrid Energy Storage And Wind Turbine Combined Power Unit

The feasibility of utilizing wind power as an alternative black start power source is challenged due to the requirement for stable power, voltage, and frequency during major grid blackouts. However, the inherent fluctuation in wind power generation and the way it is controlled pose a significant challenge. This research proposes an innovative solution that involves integrating energy storage devices with wind turbines and employing a coordinated control method between them while adjusting the control systems of the wind turbines. The proposed system integrates wind energy storage with black start power supply, emphasizing the coordinated management of multiple types of energy clusters and an advanced control method based on improved virtual synchronous machines (VSMs). This approach is particularly groundbreaking as it fulfills both rapid black start requirements and sustained stable operation of renewable energy generator units, which are crucial for their role as black start power sources. The proposed black start scheme in this paper is validated through simulation scenarios of an actual power grid, demonstrating its capability to facilitate the startup and stability control of the load required for conventional power plant black starts.
