The large-scale wind power integration using the integrated heating load and heating storage control

Abstract

Aiming at the challenge of large-scale wind power integration, a new method for integrating the heating load and heating storage control is proposed based on district energy system with a core of CHP. In the new method, thermal energy storage (TES) can increase the flexibility of CHP's heat output and power output to follow the fluctuation of wind power. The distributed electric heat pumps (EHPs) are used for heating load control to increase the capability to balance the wind power and electricity demand. In addition, the building thermal inertia and human thermal comfort are taken into account to make the power consumption of EHPs to follow the wind power. At last, the simulation results show the effect on balancing the wind power and electricity demand as well as the influence of space heating load characteristic.
