One of the main objectives of the smart grid initiative is to enable bulk power transmission over long distance, with reduced transmission losses. Besides the traditional high-voltage alternating current (HVAC) transmission, with the advancement in power electronics, high-voltage direct current (HVDC) transmission is increasingly becoming important. One of the main factors impacting the transmi...

Traditional DC-DC Boost converters are used in high voltage applications, but they are not economical due to limited output voltage, large voltage ripples, current ripples and power losses. A closed loop control scheme for a simple DC-DC Boost converter in designed and the performance characteristics are studied using MATLAB simulink. The performance of the controller is also studied for variou...

In this project a new control strategy that can be used together with such a CCC is presented. In the new control system the inverter emulates the operation of a Voltage Source Converter, in the sense that, beside the control of the active power flow through the converter, the reactive power exchange with the AC network can also be managed in order to adjust the alternating voltage of the conve...

The modern power grid is a complex and dynamic system that relies on both distributed and centralized controls. When large generation and load complexes are separated by long transmission lines, the propensity for inter-area oscillations increases. These oscillations have been identified as a hazard for utility systems since they may cause damage to equipment or restrictions on power flows over...

Over the years, high voltage transmission of large energy blocks over long distances has widely developed from Line Commutated Converter (LCC) technology. However, continuous expansion AC network and increase in renewable penetration leads to weakening Electric Power Systems (EPS), causing operational problems for LCC-HVDC. This paper evaluates degree contribution VSC-HVDC on LCC-HVDC dynamic p...

This paper presents 10-bit, 1.5 MS/s, 2.5V, Low Power Pipeline analog to digital converter using capacitor coupling techniques. A capacitance coupling foldedcascode amplifier effectively saves the power consumption of gain stages of ADC in a 0.25 μm CMOS technology. The ADC also achieves Low power Consumption by the sharing an op-amp between two successive pipeline stage further reduction of po...

A conventional steady-state power flow security check only implements point-by-point assessment, which cannot provide a security margin for system operation. The concept of a steady-state security region is proposed to effectively tackle this problem. Considering that the commissioning of the increasing number of HVDC (High Voltage Direct Current) and the fluctuation of renewable energy have si...
