In this paper the operation of 50 kW PEM fuel cell system as distributed generation is studied. The objective of this work is to develop the modeling and control framework for such distributed generation to enable their operation in a distribution system. A new control strategy for the operation of the fuel cell system in both grid connected and islanded modes is proposed to enable better management...
This paper deals with the modeling and analysis of dynamic model of solid oxide fuel cell (SOFC) system in response to the grid connection using PSCAD/EMTDC simulation software. Fuel cells are known for their reliability, power quality, eco-friendly nature and fuel efficiency. Its promising technology and extremely significant in the near future. A voltage source inverter controller is developed for...
Voltage sags are an important power quality problem for which the dynamic voltage restorer (DVR) is known as an effective device to mitigate them. This paper presents a new control algorithm for dynamic voltage restorer (DVR) that mitigates voltage sag by low active power injection with short time delay. This work is based on two-vector control technique using 12 pulse inverter. A smooth control technique...
