An enhanced strategy for new energy generation black-start based on hybrid energy storage system

Abstract

Abstract In the past few years, the connection of extensive power grids with a substantial influx of renewable energy has resulted in a growing hazard of significant power failures. Conventional black-start systems are inadequate in promptly and adaptively recuperating from such outages. Consequently, the emergence of new energy generation integrated with energy storage technology to deliver black-start services has become a prevailing trajectory. In this research article, hybrid energy storage is implemented for the wind and solar power generation system to address the issue of inadequate inertia support capacity during the black-start process. The system incorporates a virtual synchronizer to manage and replicate its inertia and damping features, thereby enhancing the black-start capability of renewable energy generation. The effectiveness of the proposed strategy is verified through simulation in Matlab/Simulink.
