摘要 随着风电等波动性新能源发电逐渐增加,高比例风电接入电网备用不足问题自益凸显。与此同时,新兴的光热发电具有可时移、可调节特性,能有效承担系统的备用需求,但光热发电受储热与光资源的强相关性约束,备用能力受限。如何利用有限的光热发电与火电进行联合备用优化,满足高比例风电系统备用需求,成为当前亟待研究的问题。首先该文分析了高比例风电接入系统旋转备用对风电消纳的影响;其次,对光热-火电联合提供旋转备用的可行性进行了分析,针对光热储热约束,提出采用电加热设备提高光热电站备用能力;然后,基于电加热设备电转热特性,建立了含电加热光热电站用电及发电调峰备用模型,基于此,建立光热发电-火电旋转备用优化模型;最后,通过改进的IEEE 30节点系统进行仿真验证,证明该文所提方法的有效性。

Abstract:As wind power and other volatile new energy generation gradually become the main power source of the grid, the problem of insufficient reserve of a high proportion of wind power connected to the grid has become prominent. At the same time, the concentrating solar power (CSP) plant has time-shifting and adjustable characteristics, which can effectively bear the system's spinning reserve demand. However, CSP is constrained by the strong correlation between heat storage and solar resources. It's reserve capacity is limited. How to use the limited CSP and thermal power to optimize the joint reserve to meet the reserve demand of the high-proportion wind power system has become a problem that needs to be studied urgently. This paper firstly analyzes the impact of high-proportion wind power connected to the spinning reserve system on wind power consumption; Secondly, it analyzes the feasibility of CSP-thermal power combined to provide spinning reserve. Aiming at the constraints of CSP heat storage, it is proposed to use electric heating (EH) equipment to improve the standby capacity of CSP. And based on the electric-to-thermal characteristics of the EH equipment and the thermal storage characteristics of the solar thermal power plant, a model of power consumption and power generation peaking standby of the EH-CSP is established, and based on this, a solar thermal power generation-thermal power rotation standby optimization model is established. Finally, the improved IEEE 30 node system is used for simulation verification, and the result proves the effectiveness of the method proposed in this paper.
