风火打捆跨区域供给电采暖的经济性评估

我国风力发电处于高速发展阶段，但受制于资源逆向分布的禀赋，弃风问题十分严峻。提出风火打捆跨区域供给电采暖的方法，以期解决大规模弃风问题，同时缓解电采暖成本过高的难题。首先，从需求侧和供给侧两端出发，提出风火打捆跨区域供给电采暖的工作原理；其次，分别建立需求侧价格上限计算模型和供给侧价格下限计算模型，评估风火打捆跨区域供给电采暖的经济性；最后，以甘肃省作为供给侧，陕西省作为需求侧，进行实证研究，验证了所提模型的科学性和合理性。

Economic Evaluation of Wind-thermal-bundled Cross-regional Power Supply for Electric Heating

Wind power generation in China is at a high-speed development stage which subjects to resources reverse distribution, and there is the very serious problem of wind power curtailment. In order to solve that problem while alleviating the problem of excessive electric heating cost, this paper proposes the method of wind-thermal-bundled cross-regional power supply for the electric heating. Firstly, the working principle of the method is proposed based on the demand side and supply side. Then the calculation models of price ceiling on demand side and price floor on supply side are established to evaluate the economy of the method respectively. Finally, with Gansu province as the supply side and Shaanxi province as the demand side, the empirical analysis is done to verify the scientificity and rationality of the proposed model.
