| Popis: | Many different type of systems have been designed to adapt photovoltaic (PV) generators to their charges. They ranged from basic and low efficient linear controllers, to more sophisticated power electronic based converters. Accordingly, depending on the system requires, further attention should be devoted to the development of the converter design that connects the PV system to the battery (BAT) or load, in conjunction with adding new and more advanced control strategies to the system. This paper outlines the process of designing a new electronic concept of a PV regulator for autonomous applications, which uses a buck converter to ensure high efficiency over a wide operating range. The power converter is driven by a very precise algorithm, adapted for implementation in a low-cost microcontroller (PIC184550), that has been designed to allow PV generator to track and function in their MPP including a control strategy that ensures an appropriate charging/discharging process for improved power management and prolonged life cycle of BAT. Besides, a software tool has been developed to supervise the various phases of the charging/discharging and the entire energy in the PV stand-alone system including the availability of continual telemetric monitoring of both PV and BAT units. The system has been developed and experimentally evaluated to investigate the behaviors of each unit of the isolated PV/BAT system. |
