Generation system reliability assessment incorporating photovoltaic energy

Abstract

The reliability assessment of generation system including photovoltaic energy has been described in this article. In general, the reliability analysis of power system can be done at three Hierarchical Levels, but here the reliability analysis of power system is performed at generation level. Therefore the reliability is accomplished at Hierarchical Level-I (HL-I). The intermittent nature of solar irradiance and failure rate of the components have been considered for the development of photovoltaic system. The annual solar data has been considered, in which the generation from the photovoltaic system is made into different states using Fuzzy C-Means clustering method. In addition, the Markov process has been implemented not only to obtain the probability of the photovoltaic model but also its frequency and duration for all the specified states. Finally, the Recursive Algorithm is used to evaluate the indices of the reliability for Roy Billinton Test System including photovoltaic unit.
