In addition DG is usually intermittent and often does not participate to the voltage regulation process. This situation may be accepted as long as the power from renewable sources (wind and solar PV) is much lower than the power generated by conventional power stations. However, due to the large amount of DG now installed, in such situations as favorable weather con ...

This paper studies the voltage stability of distribution network with DGs. According to different network interfaces and operating modes, DGs are classified into four different node types. The processing methods in power flow calculation are also analyzed in this paper. Then voltage stability condition of distribution network is derived out based on the power flow solution. According to four types of DGs, simulations and analysis of the impact on the voltage stability index are conducted. Simulation results show that the voltage stability is reduced by accessing PV-type DGs, and the quantity of PV-type DGs should b ...
