Modeling of Fuel Cell Based Power Supply System for Grid Interface

Abstract

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.

“…In this regard, many studies are being carried out and energy management system (EMS) has come out to be the most attractive topic on FCs based microgrid as suggested by authors. 61,184,198,199 In this regard the conventional current control and EMS methods need to be upgraded by proposing more intelligent control and EMS based techniques. Energy Capture Control level is devoted for optimally operating the DERs.…”

Analysis and Mathematical Model for Restitution of Voltage Using Dynamic Voltage Restorer

“…The membrane, which acts as the electrolyte, is squeezed between the two porous, electrically conductive electrodes. These electrodes are typically made out of carbon cloth or carbon fiber paper [9,10]. At the interface between the porous electrode and the polymer membrane there is a layer with catalyst particles, typically platinum supported on carbon.…”

“…PEM operating temperature is 60-100 ∘ C and efficiency is 50-60%. The control circuit monitors the utility and the fuel cell status continuously [9,10]. The traditional inverters are voltage source inverter (VSI) which consists of a diode rectifier, dc link, and inverter bridge.…”

Comparative study of current‐mode controllers for the positive output elementary Luo converter via state‐space and frequency response approaches

“…With the development of new technologies in various applications such as medical equipment design, renewable energy power systems, defence equipment, power supplies and so on, dc-dc converters with low ripples in the voltage and current, high efficiency and simple architecture are employed in order to achieve the precise output voltage regulation against parameter, line and load disturbances [1][2][3]. For example, the outputs of most of the renewable energy sources such as solar arrays and fuel cells are very low and dc-dc converters are employed to connect to the grid or battery pack [4][5][6]. One of these converters is the positive output elementary Luo (POEL) converters which are based on the voltage-lift technique [7,8].…”
