A rural heat load direct control model for wind power integration in China

Along with the increasing penetration level of wind power, limited flexibility of the coal-fired power plant based power system is becoming the bottleneck to accommodate the intermittent power in China. Heat storage is considered as the most cost-effective way to increase the power system flexibility and accommodate wind power. This paper focuses on promoting accommodating ability of wind power with rural space heating in China. Potential heat load in rural area in China is simulated first. Thermal behavior of rural residents and its control model are studied. A direct load control framework and Economic Dispatch (ED) model considering both wind power and heat load is proposed. Case study shows remarkable reduction of wind power curtailment and operational cost with the proposed method.
