A Distributed Quadratic Generation Scheduling Optimization and Reserve Allocation Approach Based on the Decomposition of Generation Characteristics

Abstract

The operation with the limited resources requires optimization. Also in an island mode on board energy system or in the large power system the optimal power generation distribution between the operating units is crucial for increase the success of the mission or for the protection of the environment or decrease the costs. A method for generator scheduling and simultaneous allocation of reserves is proposed in this article. Based on the decomposition and piecewise linear approximation of generation characteristics, we formulate the optimization framework in a distributed manner, making the utilization of parallel computing power possible. We define a finite number of operation modes for each generator, and analyze the feasibility and resulting cost of their possible combinations. Secondary and tertiary reserves are also allocated in the process. A simple heuristic is introduced to reduce the number of operating profiles taken into account.
