Solution Approach to Unit Commitment Problem Using GAMS Environment

In day to day life, with an ever-growing demand in power sector, planning and operation plays a vital role in providing an economical, reliable and efficient electricity to the consumers. In this regard, unit commitment (UC) plays a significant part in daily planning and optimal scheduling of generating units so as to meet the hourly load demand in an efficient manner. This paper focusses on presenting a robust and effective methodology for solving the UC problem using GAMS simulation environment. In this work, to assess the effectiveness of GAMS over MATLAB environment, 3 and 4 thermal generating units with and without spinning reserves and ramp rate constraints have been considered over 24-hour time horizon.
