摘要
综合能源系统(IES)是由电/气/冷/热子系统构成的复杂能源耦合体,具有能源利用率高等优点,受到业界广泛关注.首先针对由微型燃气轮机构成的综合能源系统,提出了一种基于系统辨识算法的建模和参数辨识方法,利用一段时间内观测得到的系统输入和输出数据,建立系统的黑箱模型并辨识其相关参数,重点讨论模型定阶和关键参数取值优化问题,确立了有效的评价机制,进而实现对各能源子系统内在关系的科学描述;其后,分别利用典型的综合能源系统仿真模型和Capstoni C30微型燃气轮机实验数据,验证了所提方法的有效性.
Integrated energy system (IES), which is a coupling energy system composed of electrical/gas/ cold/heat subsystems, has received intensive research due to its potential in raising the energy efficiency of the overall system.Firstly, an identification algorithm based approach was proposed to provide a simplified model for IES with microturbine,with respect to system order estimation and key parameter acquisition and model verification. According to the measurable input and output signals of IES, a black-box model is established to characterize the interaction among different energy subsystems. The developed method was tested by using numerical simulations of IES and hardware experiments in Capstone C30 Microturbine. The simulation and experimental results demonstrate the effectiveness of the proposed method.
