储能协调蓄热式电锅炉主动消纳风电的方法研究

Study on Wind Power Consumption Method Using Energy Storage Technology to Coordinate Heat Storage Electric Boilers

针对冬季供热期我国北方地区因电网风电接纳能力不足导致的严重弃风问题,提出了储能协调蓄热式电锅炉主动消纳风电的方法。在综合考虑弃风电量、储能规模、蓄热式电锅炉运行工况等因素下,建立了风电-电锅炉-储能的"源-荷-储"模型。在蓄热式电锅炉额定功率和跟踪风电弃风功率的不同运行工况下,对比分析了系统的风电弃风消纳量以及加入储能前后蓄热式电锅炉对风电弃风的跟踪效果。通过工程实例验证了该方法的有效性,为储能协调蓄热式电锅炉主动消纳风电建模提供了理论依据。

Aiming at the problem of serious abandoning wind caused by the lack of the capacity for power grid to accept wind power in the northern region of China during the winter heating period,this paper put forward a wind power consumption method using energy storage technology to coordinate to regenerative electric boilers. The＂sourceload-storage ＂model of wind power-electric boiler-energy storage was established under the comprehensive consideration of the factors such as abandoned wind power,energy storage scale and operating conditions of regenerative electric boilers. Under the different operating conditions of the rated power of the regenerative electric boiler and the power of tracking the abandoned wind power,the wind power consumption of the system was analyzed and compared. The tracking effect of the regenerative electric boiler before and after the energy storage was analyzed.The validity of the method was verified by engineering examples,which provides a theoretical basis for wind power consumption modeling using energy storage technology to coordinate regenerative electric boilers.
