寒地新能源与灵活供热煤电改造协同规划模型OA北大核心CSTPCD

In the cold northern areas,under the promotion of the "three-renovation" policy,the reasonable planning of the methods and scale for the heating reformation and flexibility reformation of coal-fired units from the view of the system can effectively improve the utilization efficiency of fossil energy and improve the acceptance capacity of renewable energy. In cold regions,power and heating systems were coupled with combined heat and power (CHP) as the coupling point. Based on this characteristic,a collaborative planning model for renewable energy and coal-fired CHP flexibility reformation was constructed from the perspective of an integrated electricity and heat energy system. In the proposed model,the current mainstream domestic reformation routes for coal-fired units,such as extraction heating reformation,high back pressure reformation,low-pressure cylinder zero output reformation,and heat storage and electric heating configuration,were considered. A divisional heat supply mode of district heating for CHP plants and boilers was considered,and an integrated optimization calculation method of cooperative planning and operation simulation was adopted. Finally,a numerical example based on a real system in North China was constructed to verify the effectiveness of the proposed model.
