Modeling and optimized control of photovoltaic energy conversion systems

The present paper presents specific issues that arise in Photovoltaic Energy Conversion Systems, being focused on maximizing the output power. There is proposed a model for Photovoltaic PV panel external characteristics. The coordinates of maximum power point are determined and used for imposing the appropriate load resistance to maximize the provided power. A comparison is made considering the classical control methods and the proposed optimized method, that prove better performances than methods based on output power measurement.
