Hyosung Heavy Industries Secures First Order for Renewable Energy Transmission and Distribution System

[Asia Economy Reporter Hwang Yoon-joo] Hyosung Heavy Industries has succeeded in securing the first domestic order after localizing the MVDC, a transmission and distribution system for renewable energy, for the first time in Korea.

Hyosung Heavy Industries announced on the 25th that as part of the Jeonnam Province Energy New Industry Regulatory Free Zone, it recently signed a supply contract for a 30MW-class MVDC medium-voltage direct current transmission and distribution system with the Green Energy Research Institute, becoming the first domestic company to do so. The MVDC ordered this time is scheduled to be installed at the Naju Innovation Industrial Complex in Jeonnam by the end of this year. The 30MW-class MVDC can supply electricity to 67,000 households.

MVDC is a system that transmits medium-voltage electricity of 1.5 to 100kV in direct current. Compared to the current transmission method of alternating current (AC), direct current transmission (DC) has the advantage of less power loss over long-distance transmission and can transmit 40% more electricity by utilizing existing transmission facilities.

Renewable energies such as wind and solar power are generated with medium-voltage electricity. For this reason, the need for MVDC technology has been raised to expand the renewable energy industry, especially in the global power market.

With Hyosung Heavy Industries applying MVDC technology domestically for the first time, more efficient transmission of domestic renewable energy has become possible.

In particular, by securing direct current transmission and distribution system technology based on proprietary technology, it is expected to have an import substitution effect in the domestic DC transmission and distribution market, which has been dominated by major overseas companies, by reducing investment costs for national key industries and facilitating installation and maintenance in the power industry.

Cho Hyun-joon, Chairman of Hyosung, said, "This achievement was obtained through persistent research and development based on Hyosung's dedication to proprietary technology," and added, "We will lead the next-generation global market as a total energy solution provider in the power industry sector."

Meanwhile, along with this MVDC contract, Hyosung Heavy Industries also signed a supply contract for a low-voltage direct current transmission and distribution system (LVDC) with Korea Electric Power Corporation.

LVDC is a low-voltage direct current transmission and distribution system used to stabilize voltage in mountainous areas. Hyosung Heavy Industries plans to install a 40kW-class LVDC in the mountainous areas of Gangwon Province this year.

With the success in securing the LVDC order, Hyosung Heavy Industries has become the first domestic company to secure technology for direct current transmission and distribution systems across all voltage ranges from low voltage to ultra-high voltage.

Hyosung Heavy Industries successfully completed a demonstration of an ultra-high voltage direct current transmission system linked to offshore wind power at the Haengwon demonstration complex in Jeju Island in 2017. Based on that technology, it is currently conducting a national project to install a 120kV 200MW HVDC at the Yangju substation of Korea Electric Power Corporation.
