Stochastic DG capacity assessment for active distribution networks considering the optimal reactive DG outputs and OLTC operation

摘要

This paper proposed a method basing on the Monte-Carol simulation to deal with the stochastic DG (distributed generator) capacity assessment problem. In this work, a newly published OLTC(on-load tap-changer) linearization model is applied to the DG capacity assessment problem. And, how the OLTC and DG's reactive output affect the DG capacity assessment result is analyzed in the case study. By using Monte-Carlo simulation method, we can get the DG capacity assessment result in different sceneries and calculate the exact risk of solar energy abandon with certain DGs' capacity in ADN(active distribution network).
