Abstract

The integration of distributed generations with a high penetration level impacts the static voltage stability of an active distribution network remarkably. Based on the probability power models of two typical distribution generations, this paper firstly presents a two-point estimation method to perform the probabilistic power flow calculation of the distribution network. Then a probability index suitable for evaluating the voltage stability of active distribution networks is proposed based on traditional voltage stability index and random probability evaluation theory. The static voltage stability evaluation method for active distribution networks is proposed and the influence of four types of load on the voltage stability is analyzed. The effectiveness of the proposed voltage stability probability index and the validity of the evaluation method are verified by simulations carried out on the standard IEEE-33 bus system.
