Abstract The more fluctuating renewable energy sources like solar and wind are integrated into the electric grid, the more it is desirable that conventional power plants actively contribute to compensating the fluctuations. For coal fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand. Model predictive control is a possible …

Fuel flow control. The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding ...
