—Electro-mechanical batteries have important advantages as compared with chemical batteries, especially in low earth orbit satellites applications. High speed slotless external rotor permanent magnet machines are used in these systems as Motor/Generator. Proper material and structure for space applications are introduced. A simplified analytic design method(More)

The main purpose of this paper is to evaluate the transient stability of power systems with increased penetration level of distributed generation resources based on calculating the maximum rotor speed deviation index. In this method, the transient stability of power systems with increased penetration level of distributed generation resources evaluated and(More)
–This paper investigates the effects of the DC link voltage of a voltage source converter (VSC)on the performance oftwo current control strategies of the VSCsfrom point of views: capability of tracking the references signals with a zero steady-state error and imposing less transients during the step changes in the references signals of the controllers. Two(More)
Fault diagnosis is a vital discussion in power systems restoration. Recently, much research endeavors have been done for fault section diagnosis of power systems by using several techniques, such as rule-based expert system, logic-based expert system, fuzzy relation based expert system, neural network, optimization techniques based approach, etc. They(More)
