Abstract
The contribute of this work is to propose a PV model-based design of a MPPT controller to harvest energy in a stand-alone wireless sensor node. Firstly a model identification of PV cell is carried out. Then the identified parameters are used to design the PV maximum power point tracker (MPPT) controller to continuously supply the wireless sensor node by a storage buffer. Additionally, the implementation of the proposed MPPT scheme is here presented. It has been implemented a rational energy management system, which uses an ultracapacitor as storage buffer, by increasing the autonomy of the system. The proposed scheme was realized and validated by outdoor tests under typical both solar and load absorption conditions.File | Dimensione | Formato | |
