Advanced photovoltaic inverter with additional active power line conditioning capability

Abstract

This paper presents an advanced photovoltaic inverter which can deliver the maximum power from photovoltaic arrays to the utility grid for all sunlight conditions, as well as simultaneously providing power conditioning to suppress power line distortions. A new control strategy is developed to maximize the inverter output from the photovoltaic array and to suppress current harmonics in the power line using a single inverter configuration. A new control strategy and experimental results are given.
