Research on the influence of load model with distributed PV generation on the voltage stability of receiving-end power grid

Abstract

The low voltage ride-through (LVRT) characteristics of DPV are first analyzed in this paper, and then the influence of the LVRT control strategies and parameters of PDGs on the grid voltage stability is studied. Finally, the influence of load model with and without DG on grid voltage stability is studied, the simulation results show that it may be too optimistic when new energy sources are not considered.
