Abstract
Recently, electric power systems face difficulties in system operations due to rapid increase in intermittent renewable energy sources (RESs), such as photovoltaic power generations (PVs). Reduction of controllable resources also yields concerns about system reliability issues. This paper focuses on a new generation dispatch method for mitigating the irregularity associated with RESs. The advantage of the proposed method is to realize both high accuracy of the solution and reduction of the computational burden by using a piecewise linear approximation. The simulation of the proposed unit commitment and the economic load dispatch are carried out to evaluate the performance of the robust supply and demand controller.
