“…The step-up transformer provides the isolation between fuel cell and load as well. Grid interface of renewable power sources like fuel cell is one of the probable areas of research in micro-grid environment [16,17]. Real and reactive power limits that can be supplied by the FCPP is an important issue that need to be addressed.…”

Renewable energy systems have developed wide interest to supply electricity in remote areas as well as for distributed power generation specially during peak loads. Fuel cell based power generation is also gaining popularity due to its cleanliness, portability and suitability for electricity and heat generation. This paper presents modeling of a fuel cell power plant in terms of fuel cell, converter and power system parameters, to facilitate operation with grid interface. The mathematical model is developed in per unit (PU) system using qd0 reference frame theory, to define the power flow (real and reactive) limits, which can be supplied by the fuel cell power plant. A single stage PWM inverter is selected as power electronic interface between fuel cell and grid.

“…First is the topology of the inverter's circuit, second is the quality and synchronization of the output power to the grid and the third subject is the control and algorithm of the MPPT. Most inverters are based on a DC/DC converter, connected to the PV array, followed by a DC/AC inverter [1]- [2]. Various synchronization methods are summarized in [3]- [5].…”

A novel design of a photovoltaic grid connected inverter is presented. The inverter is realized so as to attain current source characteristics for simple connectivity to the grid. The advantage of this realization is a simplified system due to the fact that no voltage amplitude matching or modulating is required and the w ave shape of the grids voltage has no influence. The inverter's current polarity must be taken care of in order to match the voltage polarity of the grid. The simple realization yields si mplicity in the sw itching circuitry and control. The design includes an HBridge topology that is switched by the AC grid itself; therefore no special synchronization scheme is required. Consequently, this simple switching scheme inherently suits all wave shapes and all frequency changes of the power grid. The system is combined with a Maximum Power Point Tracker (MPPT) with only output current control.
