Energy storage system consists of an energy source (running flywheel supported on bearings), energy processing system (BLDC generator and power converter) and a load which consumes energy. The useful energy at the load end can be obtained by subtracting the losses from the harvestable energy of the system.
Abstract: This paper gives an account on a hybrid energy storage system with Lithium ion battery and supercapacitor for an Electric vehicle. It is interconnected with a bidirectional DC-DC converter and the simulation results are obtained and tested for a small scale level.
Brushless DC (BLDC) motors are highly suitable for usage in high-speed applications like flywheel energy storage. A bidirectional power converter (BDC) interfaces the DC power source to BLDC machine which is coupled to the flywheel.
Since the electric motor functions as the propulsion motor or generator, it is possible to achieve greater flexibility and performance of the system. It needs more advanced energy management strategies to enhance the energy efficiency of the system.
Besides smoothing the energy output of renewable resources, energy storage systems have other technical applications in the utility grid including grid stabilization, frequency and voltage support, power quality and reliability enhancement and load shifting.
Experiments have been conducted to study the system and to test the performance of the system. The algorithm is implemented for generating the triggering pulses for power converter operating in generator mode and controlled width variation PWM pulses to maintain DC bus voltage constant at desired level at 300 V.
