ABSTRACT

Renewable energy sources (RES) like the solar and wind can't produce energy all the time due to depending air condition. But Fuel Cells (FCs) can be stored until it's needed. Power electronics plays an important role in converting the input power which is suitable delivered to the utility grid. Voltage source inverter (VSI) is the most widely used solution for connecting a low power RES tied the grid. This paper present grid tied fuel cell system using single phase phase-locked loop (PLL) based second order generalized integrator (SOGI) with proportional integral (PI) and proportional resonant (PR) current/power controllers. The SOGI algorithm is used with PLL in order to synchronize grid phase and amplitude. Solid oxide fuel cell (SOFC) which is one of FC types is analysed under constant and various DC load. Controllers of the PI and PR are discussed in order to obtain the control of inverter along with the variation of active power and grid voltage drop. The system is modelled and simulated using PSCAD/EMTDC software package. Simulation results show the effectiveness of both the controllers and PLL technique based SOGI for the synchronising of the SOFC systems with the single phase grid successfully.
