This paper presents a small-scale prototype of a wind-photovoltaic hybrid system, having batteries as energy storage components. All devices are connected to a common dc-bus using appropriate power converters. The photovoltaic modules are connected through a dc-dc buck converter using Perturb and Observe Maximum Power Point Tracking control. The permanent magnet synchronous generator (wind generator) power interface is composed of a three-phase diode-bridge rectifier followed by a buck converter. A bidirectional buck-boost converter is applied to the batteries in order to control the dc-bus voltage, to which the load is directly connected. The whole hybrid system was built as a laboratory prototype, by using a dSPACE digital controller. Several experimental results are presented in order to analyze the system performance under both steady state operation and transients. © 2012 IFIP International Federation for Information Processing.

Abstract
This paper presents a small-scale prototype of a wind-photovoltaic hybrid system, having batteries as energy storage components. All devices are connected to a common dc-bus using appropriate power converters. The photovoltaic modules are connected through a dc-dc buck converter using Perturb and Observe Maximum Power Point Tracking control. The permanent magnet synchronous generator (wind generator) power interface is composed of a three-phase diode-bridge rectifier followed by a buck converter. A bidirectional buck-boost converter is applied to the batteries in order to control the dc-bus voltage, to which the load is directly connected. The whole hybrid system was built as a laboratory prototype, by using a dSPACE digital controller. Several experimental results are presented in order to analyze the system performance under both steady state operation and transients. © 2012 IFIP International Federation for Information Processing.| File | Dimensione | Formato | |
