Reliability evaluation with wind turbines and photovoltaic panels

Abstract:

Deployment of renewable energies in networks can affect their reliability and security. This paper presents a reliability evaluation methodology in the presence of wind turbines and photovoltaic panels illustrated with IEEE-RBTS system chosen for study. The aggregated clean resources feed load points in micro grid configuration. The use of analytical methods provide partial information of reliability indices attributes due to the fact that stochastic characteristics of renewable energy are not thoroughly considered in the traditional radial topology. Thus, a Monte Carlo technique with state duration sampling simulation is applied in order to achieve a detailed analysis of reliability performance of the system. Renewables variability, periodicity, intermittency and typical distribution demand are also considered. This elaborated combination of constraints in the network is possible through the use of a dedicated computer algorithm developed by the authors and presented in this paper.
