The ever increasing development and availability of power electronic systems is the underpinning technology that enables large scale integration of wind generation plants with the electricity grid. As the size and power capacity of the wind turbine continues to increase, so is the need to place these significantly large structures at off-shore locations. DC grids and associated power transmissi...

This paper investigates the matrix converter when working as the unified power flow controller which can regulate the active reactive power flowing in a transmission line. A conventional unified power flow controller usually has a DC capacitor; this is removed in the proposed controller. This reduces the volume, improves the efficiency and lifetime, and eliminates the DC voltage control. The de...

This paper presented a variable frequency electric power transmission system (abbreviated as VFTS). The VFTS employs the unique variable frequency transformers (VF-transformers) to couple the transmission or distribution lines or networks to the sending and receiving systems. The VFTS changes the transmission frequency to provide unique features that cannot be obtained in the traditional ac and...

The new energy revolution, of which the primary energy will be based on renewable energy sources and the terminal energy will be based on electric power, will have a revolutionary impact on the future power grids. In order to develop the corresponding power grid for the future energy system, first of all, the architecture and mode of operation of the future power grid must be investigated. In t...

Using High Voltage Direct Current (HVDC) transmission lines to connect offshore wind parks to the onshore power grid has been proven technically advantageous to AC solutions and more cost-effective for relatively long transmission distances (>70km).The concept of applying DC technology can be expanded to the collection grid. DC collection grid offshore wind parks can be developed only if severa...

SHAH, CHINTAN HEMENDRA. Inductively Coupled Interconnect for Chip to Chip Communication over Transmission Line. (Under the direction of Dr. Paul Franzon). As data frequency increases beyond several Gbps range, low power chip to chip communication becomes more critical. The concept researched in this thesis is inductively coupled interconnect (LCI) over short length transmission line. The data w...

Market power assessment is a prime concern when designing a deregulated electricity market. In this paper, we propose a new functional market power measure, termed transmission constrained network flow TCNF , that takes into account an AC model of the network. The measure unifies three large classes of long-term transmission constrained market power indices in the literature: residual supply ba...

This paper proposes a fundamental and efficient control technique for introducing VSC (voltage source converter)based HVDC (high voltage direct current) transmission into a large-scale offshore wind power generation system with DFIGs (doubly-fed induction generators). The electric power from the offshore wind turbine DFIG is considerably fluctuating and unstable, and needs to be transmitted fro...

In recent years, distributed generation and a large number of sensitive AC and DC loads have been connected to distribution networks, which introduce a series of challenges to distribution network operators (DNOs). In addition, the advantages of DC distribution networks, such as the energy conservation and emission reduction, mean that the voltage source converter based multi-terminal direct cu...

With the ongoing expansion and growth of electric power industry, the use of power flow controllers is becoming more prevalent in modern power systems. The needs for system enhancement trigger the advancement of FACTS technology which offers superior features in increasing system stability and performance. Devices like TCSC can reduce line reactance significantly and thus enhance the maximum po...
