Wind Power Integration Capability Evaluation of Large-scale Combined Heat and Power System with Additional Heat Source

In recent years, with the increasing of wind farms and heat load, a huge contradiction between combined heat and power (CHP) system and wind power integration has arisen in northern China. Allocation additional heat source (AHS) such as the electric boiler (EB) and heat storage (HS) is an effective way to relieve the phenomenon of wind power curtailment in CHP system. In this paper, the improvement of AHS on system wind power integration capability is quantified, and a wind power integration capability evaluation strategy of CHP system with AHSs is proposed. The proposed strategy is applied in a practical system to evaluate the wind power integration capability, which has certain guiding significance to instruct the AHS allocation.
