Application of DC-DC converters in loosely coupled wireless power transmission systems
2017 International Conference on Smart Systems and Technologies (SST), 2017Inductive loosely coupled wireless power transmission (WPT) system is characterized by heterogeneous magnetic field of the transmitter. The voltage at receiver’s output varies with position of the receiver, with design of the receiver’s LC tank circuit, and with the load resistance. This paper measures the impact of these three parameters on receiver’s

High gain DC-DC converter for DC power transmission for offshore wind farms
2020 19th International Conference on Harmonics and Quality of Power (ICHQP), 2020The public concerns for a potential alternative power generation has been attributed to global warming, depletion of fossil fuels, greenhouse gas emissions that associated with the operation of conventional power plants, health hazards, soil degradation, ozone layer depletion and high cost of fossil fuels. The life span of reserved fossil fuel based on

Bulk power transmission by superconducting DC cable
Electric Power Systems Research, 1977Abstract It is estimated that the total electric system load in the U.S.A. will increase five- to seven-fold by the year 2000. It is reasonable to assume that the transmission line capacities will also increase at least by the same amount. For energy conservation, future transmission lines must be more efficient than those of today.

Multiport High-Power LCL DC Hub for Use in DC Transmission Grids
IEEE Transactions on Power Delivery, 2014This paper proposes an LCL dc hub concept which plays the role of a dc substation in a dc grid. The hub is capable of connecting multiple dc transmission lines with different dc voltages. Each dc transmission line can be added to or isolated from the hub without affecting the operation of the other dc transmission lines. The hub is based on multiple ac/

Power Upgrading of Transmission Line by Combining AC–DC Transmission
IEEE Transactions on Power Systems, 2007Long extra high voltage (EHV) ac lines cannot be loaded to their thermal limits in order to keep sufficient margin against transient instability. With the scheme proposed in this paper, it is possible to load these lines very close to their thermal limits. The conductors are allowed to carry usual ac along with dc superimposed on it. The added dc power

AC/DC power transmission: keynote address
Power Engineering Journal, 2002This presentation provides a high-level view of the electricity industry and the effects of reform in the industry since privatisation. The impact of this reform from the perspective of the England and Wales transmission system operator (National Grid) is discussed with reference to system design and operation.
