FREE ONLINE TUTORIAL FOR LEARNING POWER PLANT OPERATION AND MAINTENANCE … Reactive Power Control. Therefore, the RESs in normal operation cannot participate with other conventional generation sources in frequency regulation. However, several technical issues are prevalent at high level RES penetration. Power plants strip CO 2 from flue emissions today by bubbling flue gases through organic amines in water, which bind and extract the carbon dioxide. For power plants handling millions of tons of coal a year, minimizing coal dust is a high priority. THERMAL POWER PLANTS 2. This includes significant reduction in sulphur-dioxide, oxides of nitrogen, particulate matter and mercury emissions. The most important technical issue is the difficulty in achieving the frequency stability of these new systems, as they contain less generation units that provide reserve power. 2The SCR island module includes the cost of inlet ductwork, reactor, and bypass.
