Demand Response of Industrial Boiler for Power System Frequency Regulation

Abstract: Frequency fluctuation is one of the major issue of power system stability problem. By increasing the spinning reserve is the conventional way to mitigate this problem. Textile industry consume a large amount of electric energy. The industry can privilege its cost by participating in demand side management in power system grid. This paper proposed a demand side resource like industrial boiler to regulate power system frequency. Due to thermal inertia by adjusting the temperature set point of the heater of an industrial boiler, it would able to provide a fast frequency regulation without sacrificing the industrial compliance. The proposed method not only can enhance the frequency regulation during the time of power unbalance, like rapid increase in load of the industry or rapid loss of generation but also reduce the significant proportion of the total cost in textile industry. The effectiveness of the model is verified in several plausible case studies.
