Interruptible load participation as operating reserve in joint energy and spinning reserve markets using stochastic security analysis

摘要

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.
