HVDC is more environmentally friendly than AC, providing more energy per square metre over greater distances more efficiently than AC systems, as well as lower losses and less space requirements. This
The system which uses the direct current for the transmission of the power such type of system is called an HVDC (High Voltage Direct Current) system.The AC and HVDC substation, the interconnecting of an HVDC lines and earth electrodes are the main components of an HVDC system. The HVDC systems are mainly classified into three
The improvement and enhancement of power transfer capability is made possible with the advent of power electronics technologies. High voltage DC (HVDC) transmission connects two AC systems via a DC link and utilizes a power electronics-based converter. Figure 17.11 shows the typical arrangement of an HVDC system.

The HVDC transmission system provides efficient and economic transmission of power even to very long distances that meet the requirements of growing load demands. Due to its simple constructional feature and less complexity, research and development authority discovered its usage in modern power transmission.
The VSC HVDC systems in service so far have been limited to lower voltages and power ratings than CSC systems. The 500MW East-West interconnector between Ireland and Great Britain, operating at +/- 200kV, represented the highest power rating for a VSC HVDC system when it went into service in 2012. Comparison of CSC and VSC
Experts suggest major investment is needed, including in high-voltage direct-current (HVDC) interconnections. It''s no secret that the mix of power generation resources is changing in the U.S
HVDC technology is ideally suited to support and improve the sustainability, efficiency, and reliability of power supply systems. High-voltage direct current transmission systems supplement the existing AC infrastructure through. highly efficient long-distance power transmission. grid access for onshore and offshore.
An HVDC transmission system is basically environment-friendly because improved energy transmission possi-bilities contribute to a more efficient utilization of existing power plants. The land coverage and the associated right-of-way cost for an HVDC overhead transmission line is not as high as that of an AC line. This reduces the visual
The HVDC technology has advanced in many aspects since it was first introduced in the 1950s, particularly from the converter technology, power capacity and control aspects. Currently, two technologies are mainly used in HVDC systems: (1) line commutated converter (LCC) technology and (2) the voltage source converter (VSC)

Ensuring grid stability with HVDC solutions. High-Voltage Direct Current (HVDC) is a key enabler for a carbon-neutral energy system. It is highly efficient for transmitting large amounts of electricity over long distances, integration of renewables and interconnecting grids, opening up for new sustainable transmission solutions.
HVDC is more environmentally friendly than AC, providing more energy per square metre over greater distances more efficiently than AC systems, as well as lower losses and less space requirements. This increased efficiency reduces the carbon footprint of HVDC compared to AC, with losses being reduced from around 5-10% in AC
EE Power points out that the increased efficiency of HVDC over HVAC reduces losses from 5 - 10% in an AC transmission system to around 2 - 3% for the same application in HVDC. Additionally, because HVDC has lower capacitive losses than HVAC, it can travel underground, underwater, and through the air with significantly less losses in energy.
