Reliability Impact of intermittent renewable energy source integration into power system

Investigating and understanding the overall reliability impact of intermittent renewable energy source integration into power system is considerably an important activity for power utilities. In this paper, a systematic approach based on system well-being analysis framework is utilized to capture the two fundamental aspects of power system reliability, designated as adequacy and security, of a power system containing wind power generation. A sequential Monte Carlo simulation technique was used in the study to accurately incorporate the chronology of intermittent wind generation and to depict the system well-being index probability distributions in addition to the expected values. The results indicate that the system reliability implications when integrating large amounts of intermittent renewable energy source could differ considerably from conventional generation sources.
