The present work deals with the application of two stage rate limit control for battery energy storage system under different operating modes. Energy storage systems are playing very important role in renewable power systems and microgrids. Depending on the nature of power requirement, utilization of multiple energy storage units with distinguised characteristics in terms of power and energy density...
This research presents a wireless DC-to-DC power transfer over a short distance. Distance of remotely located target from the source coil and received voltage at the load are the major concern in the Wireless Power Transfer (WPT) applications. The inversely proportional behavior of these parameters degrades the system performance. In order to optimize these values and achieving transfer efficiency,...
This paper discusses about a nonlinear control technique employed for AC/DC PFC converter to charge the battery of PHEV. It consists of two stages, first stage is conversion from ac to dc where the power factor improvement is achieved by reducing the harmonics at the input side. In second stage, output dc voltage is boosted according to the requirement. The control law implemented in the first stage...
In this paper, a new control strategy is proposed for PV based DC grid system with battery and supercapacitor as a hybrid energy storage system (HESS). To complement the supply demand mismatches in a PV energy based system a hybrid energy storage system consisting of battery and supercapacitor (SC) is generally used. The traditional control approach for HESS uses the high/low pass filter (HPF/LPF)...
