ABSTRACT: To regard environmental protection renewable energy sources especially wind, has been applied to achieve emission reduction goals. While wind generation does not directly produce air pollutants emission, it causes some changes on thermal power generation scheduling which may lead them to produce more air pollutants emission especially during low and medium energy demand periods. So it seems necessary to consider air pollutants emission level in wind-thermal scheduling problems. This paper proposes a methodology for wind-thermal scheduling in a power system with high penetration of wind power subject to consider air pollutants emission reduction. Because of simultaneous minimizing total operating cost and air pollutants emission, a Multiobjective Mathematical Programming (MMP) is introduced. The computation of the required reserve levels and their costs is attained through a stochastic programming market clearing model. Also, the network constraints and the costs of both the load shedding and the wind spillage are considered. The usefulness of the proposed approach was tested through an IEEE 30-bus test system.

ABSTRACT: 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.

ABSTRACT: This paper focuses on the development of a model for interruptible load (IL) procurements within the operating reserve where energy and reserve are jointly dispatched. In this paper a stochastic mixed-integer linear programming model is utilized. Both spinning reserve and interruptible load are taken into account as the operating 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 for a power system that considers the probabilistic behavior of system's components. In this stochastic security model, accidental disturbances such as outages of generating units and transmission lines with N-1 contingencies criteria are modeled as credible scenarios. The proposed approach is tested on the IEEE-RTS for 24 hours.
