Abstract :
A single-phase three-wire photovoltaic energy conversion system with single-stage
structure using a novel maximum power-point tracking (MPPT) algorithm is
presented. An equivalent model of the proposed system is derived to analyze the
characteristics of the system and to design the controller. Owing to the linear
relation of the PV array parameters versus insolation, the model is easy to analyze.
The proposed system employs a three-leg inverter to control the MPPT process,
the line current, and neutral line current. A current-controlled MPPT algorithm
controls the MPPT. A neutral line-mode controller maintains a utility neutral line
current of zero. A line-mode controller controls the line current so as to provide
power to the utility with a unity power factor. The proposed system acts as a solar
generator on sunny days and functions as an active power filter on rainy days.
Computer simulation and experimental results demonstrate the accuracy and the
superior performance of the proposed technique.
