Electric-heat conversion is an effective way to realize local consumption of new energy and help build a clean and low-carbon heating system. To this end, a new heating substation system with new energy consumption capability is designed. The system is based on the traditional heating substation, and the adjustment equipment such as the electric boiler and heat storage tank is added. At the same time, a heating substation dispatch strategy based on the coordinated regulation of flexible resources such as the primary heat source and heat storage tank is proposed to achieve complete consumption of new energy, meet the heat load demand, and obtain the required energy capacity of the heat storage tank. Furthermore, the configuration method of the volume of the heat storage tank and its structural parameters considering the dynamic characteristics of charging is proposed to calculate the volume of hot water injected into the heat storage tank and the volume considering the thickness of the thermocline layer. The inlet and outlet pipe diameters of the heat storage tank determine through the maximum heat charging flow. Appropriate ratio of diameter to height is selected to ensure the ideal temperature stratification characteristics of the heat storage tank. The effectiveness of the proposed method is verified by a simulation example. This method can provide a reference for the local consumption of new energy and the construction of heating substations.

电热转换是实现新能源就地消纳,助力清洁低碳型供热系统建设的有效途径。为此,设计了一种具有新能源消纳能力的新型热力站系统。该系统在传统热力站的基础上,增设电锅炉和储热罐等调节设备。同时,提出了基于一次热源和储热罐等灵活性资源协同调节的热力站调度策略,实现新能源完全消纳,满足热负荷需求,并可获得所需储热罐的能量容量。进一步提出了考虑充热动态特性的储热罐容积及其结构参数的配置方法,计算注入储热罐热水的体积和计及斜温层厚度的储热罐容积。通过最大充热流量,确定储热罐的进出口管径;选取合适的高径比,保证储热罐较理想的温度分层特性。通过仿真算例验证了所提方法的有效性。该方法可为新能源的就地消纳和热力站建设提供参考。

电热转换是实现新能源就地消纳,助力清洁低碳型供热系统建设的有效途径。为此,设计了一种具有新能源消纳能力的新型热力站系统。该系统在传统热力站的基础上,增设电锅炉和储热罐等调节设备。同时,提出了基于一次热源和储热罐等灵活性资源协同调节的热力站调度策略,实现新能源完全消纳,满足热负荷需求,并可获得所需储热罐的能量容量。进一步提出了考虑充热动态特性的储热罐容积及其结构参数的配置方法,计算注入储热罐热水的体积和计及斜温层厚度的储热罐容积。通过最大充热流量,确定储热罐的进出口管径;选取合适的高径比,保证储热罐较理想的温度分层特性。通过仿真算例验证了所提方法的有效性。该方法可为新能源的就地消纳和热力站建设提供参考。

Electric-heat conversion is an effective way to realize local consumption of new energy and help build a clean and low-carbon heating system. To this end, a new heating substation system with new energy consumption capability is designed. The system is based on the traditional heating substation, and the adjustment equipment such as the electric boiler and heat storage tank is added. At the same time, a heating substation dispatch strategy based on the coordinated regulation of flexible resources such as the primary heat source and heat storage tank is proposed to achieve complete consumption of new energy, meet the heat load demand, and obtain the required energy capacity of the heat storage tank. Furthermore, the configuration method of the volume of the heat storage tank and its structural parameters considering the dynamic characteristics of charging is proposed to calculate the volume of hot water injected into the heat storage tank and the volume considering the thickness of the thermocline layer. The inlet and outlet pipe diameters of the heat storage tank determine through the maximum heat charging flow. Appropriate ratio of diameter to height is selected to ensure the ideal temperature stratification characteristics of the heat storage tank. The effectiveness of the proposed method is verified by a simulation example. This method can provide a reference for the local consumption of new energy and the construction of heating substations.
