Abstract
Abstract
System’s reserve is one of the important security constrains when conducting the day-ahead clearing calculation. Usually, the reserve requirement is determined by the local dispatching center based on their experience. However, this experience-based threshold may lead to two issues, i.e., the invalid reserve and the slow calculation speed under the electricity market condition. Based on the concept of effective reserve, a method for estimating the system’s maximum effective reserve is proposed in this paper. The main idea is to design an optimization algorithm to determine the operating unit set with the goal of maximizing the system’s effective reserve. The maximum value obtained can help the dispatching center to design the system’s reserve threshold, which is of great engineering significance. Simulation analysis verified the correctness and rationality of the proposed model through comparative analysis of multiple scenarios.
