    Abstract
  • As a flexible network reconfiguration can be applied in a distribution system, of which reliability cannot be evaluated by common methods applied in normal distribution systems. In this paper, randomness of wind generators, solar generators and loads are considered and the formula for calculating probability of a load supplied by backup sources is derived. Then a new method for fast reliability evaluation, which includes the network reconfiguration and backup sources, is proposed. A reliability evaluation for different reconfiguration schemes based on the PG&E 69-node system in USA is performed by the proposal method. The results validate the theoretical analysis in this paper and indicate that the proposed method could comprehensively evaluate the reliability and thus provide theoretical basis of the self-healing control scheme formulation and evaluation.
