Reliability evaluation for distribution systems considering flexible loads utilizing time-sequential simulation techniques

Abstract

With the development of information and communication technologies, flexible loads have become more and more popular to participate in the two-way interaction between power generation and consumption. However, the growing proportion of flexible loads has made the reliability of smart grids different from that of traditional power systems. In this paper, time-varying load model including flexible loads has been represented by developed Markov process model. Load curtailment and shifting have been considered in the developed Markov model for flexible loads. Moreover, time-sequential simulation procedures of reliability evaluation for distribution systems considering flexible loads have been developed. The proposed techniques have been validated to the modified IEEE RBTS.
