Reliability assessment for power systems with large-scale Renewable Energy Sources

This paper first to establish the reliability assessment models for the wind farms and the photovoltaic plant, and combined to the load model to assess the reliability of the power system based on the sequential Monte-Carlo simulation method. The influence on the power system reliability which is caused by different power generation capacities, access points of the new energy to the power system and the complementary access modes of the wind farms and the photovoltaic plant namely, simultaneously and separately, are all analyzed and compared in the case study computed in the IEEE-RTS79 testing system and programmed under Matlab7. The results show the effectiveness and efficiency of the proposed model and the algorithm.
