BESS Application Research for Power System Black-Start with LCC-HVDC Links Considered

Based on the general black-start constraint conditions analysis, the adaptability of BESS and LCC-HVDC to the constraint conditions of black start and their appropriate starting stage are presented. Then the black-start BESS selection scheme is offered with the BESS type, capacity and control strategy. Moreover, black-start sub-system and main grid division schemes with BESS and LCC-HVDC are discussed and the system black-start recovery path and control strategies coordination between BESS and LCC-HVDC is focused. Based on the research result above, the comparative analysis of the system black start scheme with BESS and LCC-HVDC considered and its conventional counterpart is studied.
