Abstract

Highlights: The linear models for current injections of the droop-controlled DSTATCOM and the voltage controlled DG are developed. Using the aforementioned current models, a novel linear model is proposed for power flow analysis of active distribution networks. The satisfactory performance of the proposed model has been validated by simulations on the distribution networks with DSTATCOMs and voltage controlled DGs. Abstract: Fast and accurate voltage profile estimation is of great importance for secure operation of distribution systems. In this paper, we propose a linear power flow model for calculating the voltage profile of balanced distribution networks in presence of the droop-controlled ideal DSTATCOM, the voltage-controlled distributed generation, and the voltage-dependent loads. The advantage of our proposed linear model is that both the voltage controlled units and the loads with voltage-dependent characteristic can be well considered. The good performance of the proposed model is validated on the modified 33-bus distribution network and the modified 874-bus distribution network.
