Monitoring of Photovoltaic Wind-Turbine Battery Hybrid System

The purpose of the work is to investigate a monitoring of autonomous photovoltaic battery wind turbine hybrid system (PVBWHS). The PV array, wind turbine and the storage batteries sizes are estimated based the site of application; Jazan province, KSA. The sizing result of the proposed PVBWHS is generator with 2.16kW, wind turbine generator with 2kW, Battery Bank with ~400Ah, and 5kW ratings of inverter and hybrid system controller. In this paper an intelligent graphical user interface (GUI) is built in sub-menus for system characterization. The PVBWHS modeling, simulation, and performance monitoring are also introduced. Models are made to simulate the different power sources; PV system, Wind turbine, a storage battery, the electrical loads, and required meteorological conditions. A LabVIEW model is designed whereby the hybrid system components are simulated as virtual instruments [VI] interacted with functional blocks. The developed monitoring system measures continuously the available power generated from the solar array and wind turbine, and the functional VI compare this with the actual load demand on real time estimates the storage battery operation mode.
