Abstract
Wind energy has become a significant portion of power generation resources, consequently its variability and uncertainty introduces various challenges for both the operation and planning of power systems. One of the great challenges of integrating wind energy in power systems can be seen from the reliability assessment perspective. Indeed, there is an ongoing recognized need to study the contribution of wind generation to overall system reliability and to ensure the adequacy of generation capacity. With respect to the evaluation of the reliability of power systems incorporating wind energy, a variety of criteria and techniques have been developed over the years. This paper is dedicated to reviewing the literature pertaining to generating system adequacy assessment in general and with regard to wind energy in particular. This paper firstly reviews the concepts and related aspects of generating system adequacy assessment, it also includes detailed description of the involved elements and the available widely commonly-used techniques. Then, it discusses the main issues arising when implementing wind generation into the adequacy assessment of generating systems. Moreover, the paper surveys the previously reported works that have proposed to involve wind generation into adequacy assessment.
