In the current wind power heating project in the independent heating mode

too much power from condensing thermal unit is used

and utilization rate of the electric boiler is low. So the complementary heating mode with thermoelectric plant is proposed. Based on the general modeling of electric boiler system with storage

the operation strategy and the effect of coal saving of wind power heating project with complementary heating mode are analyzed and modeled. In the case

the operation of the wind power heating project in two different modes is simulated based on the realistic data. The results show that the complementary mode can not only save coal

but also cancel the thermal storage

which has to be installed for wind power heating project in independent heating mode and then save a lot of investment.
