In today’s distribution grids the number of distributed generation (DG) units is increasing rapidly. This paper
describes the power control strategies of a fuzzy controlled grid connected hybrid photovoltaic and fuel cell distributed
generation system with battery as energy storage device. The primary source of energy for the hybrid distributed generation
system is from photovoltaic cell, fuel cell and the battery acts as a complementary source of energy. The hybrid distributed
generation system is connected to a grid through power electronic interfacing devices. A Matlab/Simulink model is developed
for the grid connected hybrid distributed generation system and fuzzy controlled power electronic DC/DC, DC/AC converters
to control the flow of power on both sides. Hybrid fuzzy model is also developed for this paper. Simulation results illustrate
the performance of the hybrid system following the load demand and operating the system with fuzzy and hybrid fuzzy
controller.
