Reliability Evaluation of AC/DC Hybrid Distribution Networks with Operation Characteristics of Vsc Converters Considered
Year: 2020
Type: preprint
Abstract: The uncertainties of outputs of distributed generators (DGs) put higher requirements on the reliability of distribution networks.Meanwhile, with the widely integrated of DGs, AC/DC hybrid distibution network is becoming a general trend.In this paper, an evaluation analysis method is proposed to evaluate the reliability of AC/DC hybrid distribution networks with high integration of DGs.The optimal load shedding model with VSCs is presented.By non-sequential Monte Carlo simulation, a framework of evaluating AC/DC hybrid distribution networks is presented.Case studies are performed on the modified IEEE 123-node network.Finally, by comparing with a modiefied AC distribution network, the reliability improvement brought by DC network is verified.
