Sungrow Achieves World-First Wideband Oscillation Reproduction and Suppression at 500 MW Plant

Published

on

HEFEI, China, Sept. 17, 2026 /PRNewswire/ — Sungrow, a globally leading PV inverter and energy storage system provider, recently has achieved a world first by controllably reproducing and successfully suppressing wideband oscillation at a real-world 500 MW solar-plus-storage plant in Qinghai, China. The field test marks a major step toward addressing one of the long-standing challenges facing renewable power systems as renewable penetration continues to increase worldwide.

As renewable penetration rises worldwide, wideband oscillation has become a major challenge, with severe cases potentially causing renewable plants to disconnect from the grid or shut down. In 2014, the BorWin1 offshore HVDC project in Germany experienced oscillations at 250–350 Hz, which damaged filter capacitors on the offshore converter platform and led to a shutdown lasting approximately six months, causing substantial economic losses to the local utility. In 2019, the Hornsea offshore wind farm in the UK experienced widespread disconnection due to subsynchronous oscillation, resulting in a loss of approximately 3.2% of the system load and affecting around one million users. Past incidents have demonstrated the significant impact of oscillation-related events.

However, the complex and unpredictable nature of the phenomenon has made it difficult to safely and controllably reproduce oscillations at real-world plants and validate effective suppression methods in the field. As a result, research has largely remained at the theoretical and simulation stage, with limited systematic validation in actual power plant environments.

To bridge this gap, Sungrow and its industry partners conducted a field test at the plant, using Sungrow PV inverters deployed across the site.

Controlled Reproduction of Wideband Oscillation

The test established weak-grid conditions and identified three key contributing factors—power output, system short-circuit ratio (SCR), and control parameters—before successfully achieving controlled reproduction of a localized system oscillation.

Rapid Suppression of Wideband Oscillation

The field test evaluated the oscillation suppression performance of Sungrow’s PV inverters under different grid conditions. Leveraging Sungrow’s patented grid-strength adaptation technology, the inverters identified grid strength within 40 milliseconds, adjusted their control strategies accordingly, and rapidly stabilized voltage and frequency.

The test also validated the effectiveness of grid-forming control in suppressing wideband oscillation. Sungrow’s grid-forming control strategy enables stable operation across a wide SCR range of 1~40 and effectively mitigates transient overvoltage.

By successfully reproducing and suppressing wideband oscillation at a real-world 500MW plant, the field test marks a critical step in moving wideband oscillation suppression from the laboratory into engineering practice, with the potential to improve the stability of renewable energy plants under extremely weak grid conditions, prevent grid disconnections caused by oscillations, unlock greater power export capacity for plants connected to weak grids, and reduce generation losses.

“For renewable energy to become a truly stable and reliable source of power, it is essential to develop autonomous fault self-healing and grid-support capabilities.” Pan Nian’an, Chief Engineer and Chief Expert for Utility PV BU at Sungrow, said Sungrow will continue to advance research and development in grid technologies, focusing on key innovations including wideband oscillation suppression, grid-forming control, and multi-energy coordination. These efforts aim to support the stable grid integration and efficient utilization of renewable energy while strengthening the technical foundation for a secure and stable energy transition and next-generation power systems.

New offerings address two distinct market needs: fixing-related exposure management and continuous quote-driven gold access.

PORT LOUIS, Mauritius, Sept. 17, 2026 /PRNewswire/ — STARPRIME is expanding its gold offering with AM/PM Fixing and XAU24/7, giving market participants two distinct ways to manage and access gold exposure. Both offerings will be available in time for Forex Expo Dubai 2026, where STARPRIME will showcase its expanded liquidity offering as a Platinum Sponsor.

The additions complement STARPRIME’s existing gold suite, including Spot XAUUSD, with contract variations for Top of Book and Order Depth, as well as XAU Futures. Together, they respond to increasingly different client requirements across physical and electronic gold markets.

AM/PM Fixing is designed for physical hedgers and other market participants managing exposure around fixing prices. Clients can trade fixing contracts directly with the STARPRIME Trading Desk, with orders subsequently converted into spot contracts. This enables exposure to be offset against other positions and may reduce margin requirements associated with maintaining separate exposures.

XAU24/7 addresses a different shift: growing demand for quote-driven products beyond conventional market hours. As continuous access becomes increasingly familiar across financial markets, the product provides around-the-clock gold trading while operating as a distinct instrument with its own pricing environment and contract specifications, including pricing generated outside traditional reference-market hours.

“Physical gold participants increasingly need efficient ways to value and hedge inventory, while another segment is seeking continuous, quote-driven access. These are very different requirements, and liquidity solutions need to evolve around both,” said Jay Mawji, CEO of STARPRIME.

STARPRIME will showcase its expanded liquidity offering as a Platinum Sponsor of Forex Expo Dubai 2026, taking place 22–23 September at Dubai World Trade Centre. Visitors can meet the team at Booth 152.
