Magnetic bearings are an attractive alternative to mechanical bearings in flywheel energy storage systems since they greatly reduce friction and wear. However, new problems are introduced in terms of stabilization; particularly the magnetic bearing must provide enough damping to reduce excessive vibrations. Two novel configurations of passive magnetic bearings are introduced to meet system requ...

The robot is being used in many applications for a different domain. delivery was developed, and the battery placed power source. Considering abnormal condition/situation during disaster period, energy critical issue robot. To overcome this condition, three kinds of sources were identified such as (i) direct energy, (ii) solar (iii) flywheel storage energy. All systems designed found that can b...

This paper presents a flywheel energy storage system, which uses a switched reluctance motor/generator. It is shown how this device can be used either together with a DVR or alone in order to attenuate the effects of voltage sags and short interruptions. In order to improve the system efficiency, some design alternatives are presented. Finite elements analyses results, validated against laborat...

The Micro-Grid (MG) stability is a significant issue that must be maintained in all operational modes. Usually, two control strategies can be applied to MG; V/f control and PQ control strategies. MGs with V/f control strategy should have some Distributed Generators (DGs) which have fast responses versus load changes. The Flywheel Energy Storage System (FESS) has this characteristic. The FESS, w...
