PEM-based Generation Adequacy Assessment of Power Systems with Non-Conventional Renewable Energy Sources

Abstract

The integration of non-conventional renewable energy sources into the electric power system is a reality around the world. However, from a technical perspective, due to its variable nature, the use of this generation technology introduces uncertainties in the performance of power systems. Thus, in this paper a generation adequacy analysis is performed. Regarding the methodology used to model the power injection of m renewable units, a probabilistic methodology that combines the point estimate method (PEM) with a non-sequential Monte Carlo Simulation (MCS) technique is presented. It should be noted that the IEEE 24-bus RTS was used as test system for the adequacy assessment. In this way, coal-fired thermal generation units were replaced by non-conventional renewable energy sources (solar and/or wind). In addition, the performance of these technologies was analyzed along with the effect of increasing their capacity on the different adequacy indices.
