Robust and Economical Scheduling Methodology for Power Systems Part Two Application Examples

A generalized framework of power system robust dispatch is suggested in the previous paper that places the unit commitment problem and reserve adjustment problem under large scale wind energy integration as examples to demonstrate the practical application of the robust and economical scheduling methodology.The robust unit commitment(RUC)is aimed at providing optimal unit status decisions immune to all possible wind power variations within a pre-defined uncertainty set,while the robust reserve adjustment(RRA)tries to guarantee the reachability to a new secure operating condition when the forecast error of wind power generation is high.Through the two examples of RUC and RRA,this paper highlights the process of developing a robust model within the framework of robust and economical scheduling and the method of solving such a problem so as to provide more reliable and cost-effective operation in an uncertain environment.The effectiveness of our models and algorithm are validated on an IEEE 39-bus system.
