doi:10.11930/j.issn.1004-9649.201705105

Abstract

Abstract: In hybrid AC/DC receiving-end grid, power shortage and power transfer would occur after DC blocked faults, and it could cause chain faults. A load shedding scheme configuration method is proposed through analysis of power transfer coefficient of DC or load shedding buses and AC transmission lines, along with consideration of load importance factor. The simulation results for a hybrid AC/DC receiving-end grid in Zhejiang power grid proves feasibility and effectiveness of proposed method.

Key words: hybrid AC/DC system, power transfer coefficient, load shedding scheme, security and stability
