Abstract

Based on the traditional research on the unit commitment considering active power security constraints, the voltage and reactive power constraints are further introduced to build a relatively comprehensive model. Using Benders decomposition, the optimization problem is decomposed into a master problem and a subproblem and the corresponding iterative process is also proposed. The master problem solves unit commitment considering security constraints based on the DC power flow model, the subproblem is composed of a series of reactive power optimization problems. Benders cuts guided by the subproblem form the additional constraints correlating the master problem and the subproblem.
