Sungrow Inverters Achieve Key Regulatory Milestone in Brazil for Renewable Energy Systems

Sungrow Inverters Achieve Key Regulatory Milestone in Brazil

Sungrow, a renowned leader in PV inverters and energy storage solutions, has recently achieved a significant milestone by attaining official approval from Brazil's National Electric System Operator (ONS) for its dynamic inverter models. This validation marks a pivotal moment for the company as it underscores commitment to technical excellence and puts a spotlight on the capability of their products during critical operational challenges.

Understanding the Significance of this Approval

The approval from ONS is vital as it confirms that Sungrow's inverters meet stringent compliance standards necessary for the integration and functionality within Brazil's national electricity grid. The inverters are now recognized for their reliable performance during electromechanical and electromagnetic transients, which is crucial for the stability of the power sector.

The recent history of Brazil's electricity landscape highlights the importance of this achievement. In August 2023, a significant blackout revealed vulnerabilities within the grid, emphasizing the necessity for improved confidence in the operational characteristics of inverter technology, particularly during system disturbances. The widespread event prompted ONS to introduce a structured approach to assess and verify the dynamic models of inverters and power plant controllers, aimed at fortifying the reliability of power system simulations.

A Rigorous Validation Process

In partnership with ONS, Sungrow conducted an exhaustive validation process for its inverters, employing advanced simulation tools such as PSCAD and ANATEM. This two-tiered validation process has been essential in analyzing dynamic occurrences, including switching operations and faults that could occur within the grid.

1. Inverter Level 1 (L1): The validation commenced with Sungrow's use of a semi-physical controller to verify its PSCAD models. This step was crucial to ensure that the simulations corresponded accurately with the hardware performance of the inverters.

2. Inverter Level 2 (L2): Following this, a second model based on the PSCAD validation was developed using ANATEM. This model was then cross-checked to ensure consistency between both simulation platforms, cementing the reliability of the results.

Throughout this process, Sungrow has prioritized the collaborative partnership with ONS, recognizing the operator's role in fortifying the Brazilian National Interconnected System (SIN). The company invested considerable resources into this initiative, forming a local team support by global research and development expertise to navigate this complex validation process thoroughly.

Impact on Brazil's Renewable Energy Future

Ada Li, the Vice President of Sungrow Americas, expressed that this endorsement reinforces Sungrow's dedication to delivering high-performance and compliant energy solutions integral to Brazil's ongoing ambitions towards modernization of its power system. With the official approval now received, all variants of Sungrow's inverters sold in Brazil, including central inverters and modular inverters, are recognized as compliant with national standards.

Sungrow has established itself over the past 28 years as a key player in advancing renewable energy technology. As of December 2024, the company has deployed 740 GW of power electronic converters globally and stands as the most bankable PV inverter and energy storage company worldwide. Through continuous innovation, Sungrow aims to facilitate clean energy projects globally, supported by a robust customer service network.

As the urgency for renewable energy solutions escalates amid the growing concerns about climate change, Sungrow's achievements in Brazil symbolize a critical step in the broader transition to sustainable energy solutions. The approval not only enhances the company's reputation but also strengthens Brazil's commitment to better integration of renewable technologies into its energy landscape.
