“…Maintaining the constant steam temperature increases, the lifetime of the boiler and steam turbine while reducing thermal stresses [3]. In order to decrease CO 2 emissions, power generation from alternate renewable energy sources has grown incomparably over the past five years, forcing changes in the operating requirements of conventional power plants [4]. Although a power plant is initially designed to operate at its base load, it needs to be efficient, flexible, and capable of handling changes in load demand and variations in power generation profiles from renewable energy [3].…”

<p>A superheater is a vital part of the steam generation process in the boiler-turbine system. Reliable control of temperature in the superheated steam temperature system is essential to guarantee efficiency and high load-following capability in the operation of coal-fired Thermal power plant. The PI and PID controllers are extensively used in cascade control of secondary superheated steam temperature process.The design and implementation of a Model Predictive Control (MPC) strategy for the superheated steam temperature regulation in a thermal power plant is presented. A FOPTD model is derived from the dynamic model of the superheater. This model is required by the MPC algorithm to calculate the future control inputs. A new MPC controller is designed and its performance is tested through simulation studies. Compared with the superheater steam temperature control using a conventional PID controller, the steam temperature controlled by the MPC controller is found to be more stable. The stable steam temperature leads to energy saving and efficient plant operation, as verified by the simulation results. </p>
