Experimental investigation of power management and control of a PV/wind/fuel cell/battery hybrid energy system microgrid.

This paper presents an experimental study of a standalone hybrid microgrid system. The latter is dedicated to remote area applications. The system is a compound that utilizes renewable sources that are Wind Generator (WG), Solar Array (SA), Fuel Cell (FC) and Energy Storage System (ESS) using a battery. The power electronic converters play a very important role in the system; they optimize the control and energy management techniques of the various sources. For wind and solar subsystem, the speed and Single Input Fuzzy Logic (SIFL) controllers are used respectively to harvest the maximum power point tracking (MPPT). To maintain a balance of energy in the hybrid system, an energy management strategy based on the battery state of charge (SOC) has been developed and implemented experimentally. The AC output voltage regulation was achieved using a Proportional Integral (PI) controller to supply a resistive load with constant amplitude and frequency. According to the obtained performances, it was concluded that the proposed system is very promising for potential applications in hybrid renewable energy management systems. • Realization of an experimental wind turbine emulator based on an induction motor. • Implementation of the Single Input Fuzzy Logic MPPT controller for PV Emulator. • DC bus voltage regulation based on the Fractional Order PID controller. • Power management strategy for a hybrid system based on the battery state of charge.
