| 摘要: |
| 电力系统与热力系统协调优化运行是提高风电消纳能力的有效方法。针对热能传输与电能传输不同的特点，进一步研究热网特性对风电消纳的影响。首先结合热网水力模型及其实际热网结构与运行特点，提出了一种热网实用水力模型。然后在建立延时和衰减等热网特性方程及电热耦合模型基础上，构建了计及热网特性的电热联合系统调度模型。该模型不仅方便考虑延时和衰减等热网热性，而且不需解算热网水力模型，简化了约束条件，编程简单。算例分析表明，热网特性对电热联合系统优化调度结果及风电消纳率影响较大，延时特性有利于风电上网，而衰减特性则对风电上网不利。 |

| Abstract: |
| The coordinated optimization operation of power system and thermal system is an effective method to improve wind power consumption capacity. Aiming at the different characteristics between heat transfer and power transfer, this paper gives a further research on the impact of the heating network characteristics on wind power consumption capacity. Firstly, combining the heating network hydraulic model and its actual heating network structure and operation characteristic, this paper introduces a functional heating network hydraulic model. Then, based on the establishment of the heating network characteristics equation of delay and attenuation and the heat-electricity coupling model, a heat-electricity combined scheduling model considering the characteristics of the heating network is built. The model not only is convenient to consider the characteristics of delay and attenuation, but also simplifies the calculation of hydraulic model and the constraints of the scheduling model, which is also easy programming at the same time. A numerical example shows that the heating network characteristic can greatly affect the heat-electricity combined optimal scheduling result and wind power consumption capacity, the delay characteristic is conductive for the wind power integration, and the attenuation characteristic goes against the wind power integration. This work is supported by Science and Technology Project “Research and Application of Key Techniques of Combined Thermoelectric Dispatch Considering Safety and Economy” which belongs to State Grid Corporation of China. |
