A Hybrid Stochastic-Robust Approach for Power System Security-Constrained Scheduling in the Presence of Flexibility Facilities

One of the main characteristics of a smart grid is its responsiveness to uncertainties. Conventional uncertainties include failure of power system components such as generation units. On the other hand, with the increasing growth of renewable energy resources, the uncertainty related to the generation of these resources will increase the challenges of power system operation. Therefore, in this article a hybrid stochastic-robust scheduling approach is proposed to overcome the abovementioned challenges. This approach provides a platform so-called “Selective Decision Making Platform (SDMP)” for robust decision-making due to the integration of risk measures. This platform is devised for the power system operator as a decision support tool for tackling uncertainty challenges. In the proposed SDMP, Capacity Outage Probability Table (COPT) has been used for considering the conventional uncertainties based on stochastic consideration of N-K contingencies. This will increase the accuracy and practicality of the scheduling in the face of possible multiple contingencies. Along with conventional generation resources, technical and economic characteristics of other flexibility facilities including storage technology and demand response are also integrated in the scheduling model. The simulation results on IEEE RTS indicate the suitable performance of the proposed scheduling approach from various aspects of techno-economic decision-making.
