Improvement of thermal efficiency for combined cycle power plant during load following operation

An optimization method for unit startup and shutdown timing in the load control system is proposed for combined cycle power plants to improve thermal efficiency during load following operation. The optimum timings are derived from regression equations obtained through offline dynamics simulation ana...
