Abstract:A large number of new energy access brings huge pressure to system peak regulation, which makes thermal power units enter the deep peak regulation mode and increases the unit power generation cost. Therefore, it is necessary to find new peak regulation resources to participate in reducing the intermittenity of new energy output. Electrolytic aluminum is a high quality peaking resource with large load capacity and millisecond adjusting speed. Based on this, first of all, based on the series current, temperature and output of electrolytic aluminum load production process and other factors, the electrolytic aluminum load participation system peak regulation model is established. Combined with the division of thermal power unit speed peak regulation stage, an event-driven peak regulation scheduling model is constructed. The real-time output of thermal power unit is taken as the event trigger mechanism to trigger different objective functions of the peak regulation model. To achieve the purpose of differentiated regulation. The results of the example show that the proposed model can improve the new energy consumption rate and electrolytic aluminum output, and reduce the unit power generation cost of thermal power units.
