Control of Electric Boiler with Heat Storage for the Mitigation of Wind Curtailment

This paper focuses on the research of using energy coupling devices under the integrated energy system to support the mitigation of wind curtailment. The Electric Boiler with Heat Storage (EBHS) is selected as a typical energy coupling device which can decouple the heating and electricity network. A model and the control strategy of EBHS was developed. A coordinated control strategy of the EBHS in a CHP power plant to support the heating loads while reducing the CHP plant power output in order to increase the utilization of wind generation was studied. Simulation was carried out and analyzed to verify the benefits of the coordinated control strategy in terms of mitigating the wind curtailment.
