Abstract
Distributed generation provides a new solution for the accommodation of renewable energy under the double carbon goal. The increasing load especially the EV penetration leads to voltage problem. DGs connected in the distribution system will impact the static voltage stability (SVS) in distribution networks. In our work, the power-voltage curve (P-V curve) is tracked by continuous power flow (CPF) and the maximum load parameter can be got. CPF, SVS and maximum load parameter is introduced first. Then, the continuous power flow with DG model is established. At last, CPF principal is used to evaluate the static voltage stability of the distribution network and SVS support ability of DG can be estimated. The proposed method is simulated in the IEEE 69-bus distribution network. The influence of capacity and positon of DG on SVC support capability is simulated. The results are discussed in the end.
