Abstract:
In this article, we propose a model for a stand-alone hybrid distributed generation system. In this model, the input sources are distributed DC sources like solar panels or batteries. The idea behind this network framework is to introduce a hybrid DC/AC network, feasible for small and remotely located areas with stand-alone DC grids, in the vicinity of larger towns requiring a functional AC connection. The behaviour of the system in the steady state is analysed, and the network is mathematically represented with port-controlled Hamiltonian modelling. Stabilization to the desired voltage, both AC as well as DC, is attained with nonlinear passivity-based control taking into consideration not only the energy characteristics but also the inherent physical structure.
摘要:
在这篇文章中,我们提出了一个独立的混合分布式发电系统的模型。在这个模型中,输入源是分布式直流电源,如太阳能电池板或电池。这个网络框架背后的想法是引入一个混合DC/AC网络,适用于具有独立直流电网的小型和偏远地区,在需要实用交流连接的大型城镇附近。分析了系统在稳态下的行为,网络在数学上由端口控制的哈密顿模型表示。稳定到所需电压,交流和直流,通过基于非线性无源性的控制来实现,不仅考虑了能量特性,而且考虑了固有的物理结构。
