Optimum Simultaneous Clearing of Energy and Spinning Reserve Markets with High Penetration of Wind Power

This paper focuses on the development of a model for Interruptible Load (IL) procurements within the operating reserve where significant wind power capacity are available through the grid. In this paper a stochastic mixed-integer linear programming model is utilized. This model considers the network constraints and takes into consideration the cost of both expected load not served and all kind of reserve. Both spinning reserve and interruptible load are taken into account as the reserve services. The characteristics of the procurement of interruptible load such as locational aspect of the IL, different offer in each IL's agent, maximum and minimum IL's quantity participation are explicitly considered. The main purpose of this paper is to determine a sufficient amount of spinning reserve in a power system with a high penetration of wind power that considers the accidental disturbances such as outages of generating units and transmission lines and errors in the forecasts of wind power production, simultaneously. These uncertainties are modeled as credible scenarios. The proposed approach is tested on the modified IEEE-RTS for 24 hours.
