Power System Reliability Assessment Considering Impacts of Climate Change

Abstract

Power system reliability, as one of the most significant issues in power system studies, is affected remarkably by load demand changes. On other hand, climate changes and global warming lead to increasing the electricity demand of a power system. In this paper, the impacts of global change on generation power system reliability indices have been investigated. Loss of Load Probability and Expected Energy Not Supply are considered as power system reliability indices. In addition, a Particle Swarm Optimization method is used to assess these reliability indices. IEEE_79 Reliability test system is selected as a standard test system. The results show that reliability indices are affected noticeably by temperature rising and climate change.
