A comprehensive model for security-constrained unit commitment considering renewable energy resources

Abstract

This paper presents an effective method for deriving stochastic solution to the security- constrained unit commitment (SCUC) problem, which takes into account wind uncertainties via effective scenarios. Increasing penetration of intermittent renewable generations forces independent system operators (ISOs) with new challenges for the economic and secure operation of power systems. The proposed model is applied to a modified 24-bus IEEE Reliability Test System considering two case studies. The case studies investigate the effect of PV arrays in the stochastic SCUC problem. The simulation outcomes confirm the applicability and effectiveness of proposed model.
