基于分区分类动态无功储备的电网暂态电压稳定性评估
Transient voltage stability assessment based on zoned and classified dynamic reactive power reserve in power systems
摘要
Abstract
Transient voltage stability has become a critical challenge in power systems with high penetration of re-newable energy sources(RES).Assessing transient voltage stability from a reactive power perspective provides in-sights 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 volt-age stability assessment method is then developed,leveraging zoned and classified DRPR.Simulations on the CSEE-VS benchmark system demonstrate the method's validity.关键词
