The fault current level is different in grid connected and islanded microgrid fault cases for the same relay due to large integration of distributed energy resources in the latter. Therefore, protection systems must be adaptive and assisted with extensive communication networks to respond to the dynamic changes in the microgrid configurations. However, the microgrid must be protected even under the...
Charging time and power transfer efficiency are the main issues of wireless power transfer for electric vehicle. It is proposed in this paper to resolve both of the issues using the concept of transformer induction. An autonomous robot arm equipped with several sensors is mounted to the vehicles undercarriage to carry the receiving coil and locate it at the right place which is into the transmitting...
Several factors are considered when designing a Wireless Power Transfer (WPT) system for Electric Vehicle (EV) charging. These include the efficiency of the system, amount of power transferred, near field emissions, cost, and weight. Reaching the best combination of design parameters often requires trade-offs between them. Accordingly, and starting from a given coil design, this paper proposes an...
