^4fIMPACTS OF EMBEDDED GENERATION ON VOLTAGE STABILITY OF DISTRIBUTION SYSTEM

摘要

^7fCurrently, the influences of electricity market liberalization and the Kyoto agreement have led to a profound change in the electricity system. This has resulted in an increased use of non-dispatchable decentralized or embedded generation connected to the local distribution systems. Embedded generation can have a significant impact on the power flow, voltage profile and the power quality for customers and electricity suppliers. This requires a suitable tool to analyze the influence of such technologies on the distribution system. In this paper, the models of distribution system components are developed for distribution load flow and voltage stability analysis. Then, the voltage steady-state stability and an initial approach to voltage dynamic stability are studied with several embedded generators under different load characteristics.
