As a black-start power supply, distributed generation exhibits higher flexibility in terms of structure, and it is also more rapid in response speed. However, during the system restoration and construction process, the PV-storage black-start power supply based on self-synchronous voltage source control may experience frequency fluctuations, posing a risk of failure in the subsequent black-start process of power grid. To enhance the suppression effect on frequency fluctuations during the construction process, an improved self-synchronous voltage source control strategy for an interface inverter in the PV-storage black-start power supply is proposed. This improved control strategy improves the stability of the PV-storage black-start power supply, laying a foundation for the smooth implementation of subsequent black-start process. Meanwhile, simulation analysis and experimental verification were also presented, providing a detailed validation of the proposed control strategy and theoretical results.
