Research and Development of a Unified Approach to Operations Scheduling for Electric Power under Uncertainty

摘要

Operations scheduling in the electric power industry concerns the operation of the generating facilities over the time period ranging from an hour to several years. Operations scheduling links the minute-by-minute automatic generation control with long-term investment decisions. Traditionally, operations scheduling has included the problem of unit commitment, hydroscheduling, and maintenance scheduling. Additional problems are scheduling of limited fuel, stored energy, controllable load and nuclear refueling. The integration of the component problem into a unified approach was a major goal of this research. This report presents research into a unified approach for solving the operations scheduling problem under uncertainty. The research has investigated methods to decompose the problem in a consistent manner. Two methods of decomposition are described in this report: temporal decomposition, and spatial decomposition.
