| Title |
A Single-Phase Grid-Tie Photovoltaic Inverter With Maximum Power Point Tracking and Active Power Curtailment |
| Supervisor |
Dr. Luiz A. C. Lopes |
| Description |
Single-phase voltage source inverters are often used for interfacing photovoltaic (PV) sources to the utility grid. In order to increase the power/energy yield, maximum power point tracking (MPPT) algorithms are frequently used. In some cases, PV inverters are connected to a diesel generator set (genset) based isolated power system, in what is called a hybrid mini-grid. In these cases, the grid frequency typically presents larger frequency and/or variations and it is desirable that the power sources presentment a feature called active power curtailment (APC) which can assist with the stability and power quality of the system.
This project deals with the design, implementation and testing of a single-phase grid-tie PV inverter with maximum power point tracking and active power curtailment. A prototype will be implemented based on the TI renewable energy developer's kit. This consists of a power electronic converters and a dedicated digital signal processor (DSP) for control, monitoring and generation of the required gating signals.
As power sources, a programmable solar array simulator (AGILENT) can be used for indoor tests and PV panels for a final test.
