Reliability-Security Constrained Unit Commitment based on benders decomposition and Mixed Integer Non-Linear Programming

Reliability-Security Constrained Unit Commitment (RSCUC) with emphasis on Mixed Integer Nonlinear Programming (MINLP) and Benders Decomposition (BD) based on thermal generating units are presented in this paper. To solve unit commitment problem generalized BD along with reliability issues are considered. The approach presented in this work allows the decomposition of the whole program in quadratic mixed integer master program and network security check non-linear sub-problem. The case study demonstrates the effectiveness of the proposed approach.
