6. On Reliability Methods Quantifying Risks to Transfer Capability in Electric Power Transmission Systems
Abstract : In the operation, planning and design of the transmission system it is of greatest concern to quantify the reliability security margin to unwanted conditions. The deterministic N-1 criterion has traditionally provided this security margin to reduce the consequences of severe conditions such as widespread blackouts. READ MORE

7. Power Control Systems in a Flywheel based All-Electric Driveline
Abstract : Flywheel systems are attractive in hybrid and electric vehicles due to their ability to handle power during acceleration and braking. The combination of a flywheel device with a battery source has several advantages such as high peak power capacity, high energy density and reduction in the number of charge/discharge cycles of the battery.
