Voltage Sag Assessment of Distribution Network with Distributed Generations

Abstract:

Voltage sag assessment of distribution network with DGs based on Monte Carlo method is researched in this paper. Models of synchronous machine type DG and inverter type DG are established respectively; then a typical distribution network with DGs is simulated based on PSCAD/EMTDC. Impacts of type, control strategy, output power and location of DG on voltage sags are discussed based on several simulation examples. The results show that inverter type DG has certain capability of suppressing voltage sags and can reduce the frequency of voltage sags in distribution network and the impacts are depend on its type, control strategy, output power and location.
