This paper proposes a novel bilateral inertia and damping emulation (BIDE) control scheme for VSC-HVDC transmission systems that can autonomously provide inertial responses to two interconnected asynchronous AC grids in similar fashion of synchronous generators. For each VSC station, the energy comes from augmented DC link capacitance whereas grid on other side. proposed approach is communicati...

The paper aims to exploit multi-terminal VSC-HVDC for wind farm interconnection and seek a control strategy that can improve the operational characteristics of the interconnection system. Firstly, the paper introduces the basic structure of the wind farm interconnection system and details the wind farm control schemes, including pitch angle control and rotational speed control. Secondly, it exp...

Pole-to-pole DC faults on HB-MMC-VSC-HVDC schemes impose significant risk of cascade failure IGBT/diode pairs. Other novel topologies with fault blocking capability, i.e. AAC converters, and circuit breakers are not yet fully matured. Therefore, silicon thyristors used to bypass the until AC activate. However, also at due capacitor voltage collapse high junction temperatures caused imbalanced r...

The communication infrastructure of the modern Supervisory, Control and Data Acquisition (SCADA) system continues to enlarge, as hybrid High Voltage Direct Current (HVDC)/Alternating (AC) networks emerge. A centralized SCADA faces challenges meet time requirements two different power topologies, such employing toolboxes for both grids. This paper presents a HVDC/AC network. In addition, case st...

In the last few years, many offshore wind power plants are installed at North Sea and more under construction. Offshore grid would be vital in integration of future plant with main land grid. Both, multi-terminal DC AC cable systems consideration concept The reactive voltage operating point for such a network is important optimized operation. This article presents an optimization criterion cont...

Electrically isolated areas are separated by a great distance and, normally, have considerably low demand; in consequence, these non-interconnected from the main power grid or electrical national transmission systems. Great and demand reasons why an interconnection project high voltage AC is not feasible most of cases. Nevertheless, there some with even though they large distances hard terrains...
