| description | Transient voltage stability has become a critical challenge in power systems with high penetration of renewable energy sources （RES）. Assessing transient voltage stability from a reactive power perspective provides insights into the system’s reactive power compensation requirements. This paper proposes a classification of dynamic reactive power reserve （DRPR） into short-term and long-term categories based on their dispatchable duration and the system’s multi-timescale reactive power demand following disturbances. Calculation methods for the maximum effective capacity and minimum required capacity of each category are respectively proposed. A novel transient voltage stability assessment method is then developed， leveraging zoned and classified DRPR. Simulations on the CSEE-VS benchmark system demonstrate the method’s validity. |
