In this paper, battery/ultracapacitor hybrid energy storage system (HESS) is proposed for electric vehicles, it is used to large dc-dc converter by using ultra capacitor and battery. It is also use the dc link for the purpose of maintain the peak voltage value. By the help of battery and ultracapacitor they are operate. The battery is used to charging the capacitor in case of discharge the capa...

Wind power parallel operation is an effective way to realize the large scale use of wind power, but the fluctuations of power output from wind power units may have great influence on power quality, hence a new method of power smoothing and capacity optimized allocation based on hybrid energy storage technology is proposed in terms of the uncontrollable and unexpected characteristics of wind spe...

This paper presents a standalone hybrid power system using wind/PV/diesel/Battery energy system with Matlab/Simulink environment. PV & Wind are the primary power sources of the system and battery is used as a backup for long run application. Here we have also compare the performance of PV/Wind/Battery connected system with PV/Wind/Diesel connected hybrid power system. The most frequently used r...

It has been shown that none of any energy sources which own high specific energy or high specific power, but not both, can solely fulfil all the demands of hybrid electric vehicle (HEV) in some circumstances. In this paper a simulation model for battery/ultra-capacitor hybrid energy storage system (B/UC HESS) was presented by Matlab/Simulink. Based on the model a low-pass filtering control stra...

This work presents a battery-ultracapacitor hybrid energy storage system (HESS) for pulsed loads (PL) in which ultracapacitors (UCs) run the pulse portion of load while battery powers constant part load. Energy stored UC depends upon square its voltage that’s why an active parallel topology with two bidirectional converters (BDC) is employed here that assigns separate BDC to control betw...

In this paper, the development and optimization of Power Distribution Control Strategy (PDCS) have been performed for a Hybrid Energy Storage Systems (HESS) of a Series Hybrid Electric Bus (SHEB). A common PDCS is based on the use of Ultra-Capacitor (UC) pack. A new simple PDCS is developed as a battery based one. For the battery based PDCS, four parameters ar...

Using the energy power supply concept, this paper proposes a DC voltage source with limited energy storage capacity, which models: the energy storage capacity of the batteries, the involved energy transfer process and the constant voltage output behavior when the battery has storage energy. Further, this circuit source is used for understanding the combined electrical circuitbased battery model...
