考虑管网衰减延迟特性的分布式能源站实时出力计算

Prediction approach of hourly output of energy station in distributed energy system based on attenuation and delay features of pipe network

建立了区域能源系统输配管网衰减延迟模型,将供能区域内各建筑的逐时负荷需求转化为能源站的逐时出力,使得区域能源系统需求侧负荷趋向于平准化,并作为能源系统容量匹配和运行优化的基础。针对同一供能区域中的3种能源站位置情景,分别计算了能源站实时出力的曲线。结果表明,各用户负荷的叠加值与能源站的出力相差加大。

Establishes an attenuation and delay model of pipe network of district energy system. The model can transform the hourly load of each building into the hourly output of energy station which makes the load to level and be as the basic of capacity matching and optimal operation of energy system. Furthermore, calculates the hourly output of energy station based on three cases in the same location. The results show that it is quite different between the load superposition value of all the users and the output of energy station.
