A Novel Hysteresis Power Point Optimizer for Distributed Solar Power Generation

Abstract

This paper proposes a new photovoltaic panel maximum power point optimizer based on a buck converter. It can be connected to the dc-link distributed energy harvesting system that should perform the true maximum power point tracking algorithm based on maintaining constant dc-link voltage. The algorithm is based on the hysteresis sensorless control and provides high efficiency. Proposed solution is recommended to be used in small- and medium- power systems where the price of the conventional maximum power point tracking converter is very high and comparable to the cost of the individual panel.
