摘要

This paper investigates the impact of power-electronic Converter Interfaced Generators (CIG) connected at the distribution network on bulk power system long-term voltage stability. In particular, the CIG effect on instability onset, on-line stability monitoring and protection against voltage collapse is examined using an IEEE Test System properly modified to include significant CIG penetration. Several simulations are executed to evaluate the CIG impact on instability onset and determine the performance of a voltage instability monitoring method, as well as of three protection scheme variants. Different CIG connection topologies, as well as reactive control modes are examined. Conclusions drawn show significant impact of CIGs and demonstrate the need for specific countermeasures design that account for CIG interaction with traditional protection measures.
