abstract:
In the heating season in the northern China, the existence of “thermoelectric coupling” for cogeneration units is the main cause why wind power is abandoned. Wind power heating is an effective way to dissipate wind power. First, the time-of-use price strategy could optimize the system load curve to increase the potential grid-connected wind power. Second, the wind power heating project adopts the electric boiler with heat storage, which is complementary to the thermal power plant, as the main means of consumeing the wind power. By taking the lowest system operating cost as the objective function, and considering the demand response and the heat supply of the storage-storage electric boiler, an electric-heating combined system scheduling model was constructed. CPLEX is called in Matlab to solve the unit combination, demand response, and heat-storage of the storage-storage electric boiler in the model. It shows that the method can improve wind power consumption and reduce primary energy consumption compared with the traditional cogeneration scheduling model.
