Characterisation and evaluation of flexibility of electrical power system

Abstract

This paper aims to clarify flexibility by summarizing the analytic frameworks that have recently emerged to measure operational flexibility. Flexibility has been identified as an essential property of power systems, and indices and metrics used to recognize and evaluate a power system flexibility are continually defined. In this paper some indices and metrics that have already been developed are briefly presented and discussed. Also different methods for enhancing the flexibility are presented in more details.
