Navigating the Challenges of Photovoltaics Amid the Green Wave: Guoneng Rixin’s Solutions to Reverse Flow Issues

In the wave of green energy development, distributed photovoltaic (PV) generation has become the preferred choice for many households and businesses looking to achieve energy transformation. For distributed PV plants that operate on a self-consumption basis without feeding excess power back to the grid, the grid requires that the electricity generated be consumed by local loads. Any surplus electricity must also be consumed by loads at the same level, and excess power generation is limited to prevent reverse power flow.

With the introduction of the “531 New Policy,” stricter constraints have been placed on the self-consumption ratio, increasing the demand for effective solutions to prevent reverse power flow. In this context, Guoneng Rixin has developed the “Distributed PV Reverse Power Flow Control Device.” This innovative technology monitors system operational status in real-time and accurately regulates power output, effectively avoiding reverse flow and safeguarding the stability of the power grid.

Intelligent Protection of the Grid: Clear Policy Directions for Reverse Flow Prevention

Against the backdrop of global energy transformation, policies for reverse power flow prevention in distributed generation systems are continually improving. From a technical standpoint, governments worldwide have established comprehensive technical standards aimed at ensuring grid safety. For example, China’s standards, including GB/T 19939-2005 on grid connection technical requirements for PV systems and GB/T 29319-2012 on technical specifications for PV power systems connecting to distribution networks, include measures to prevent power reverse flow that could damage the grid.

In terms of policy design, governments are using economic incentives to guide compliance. Projects equipped with advanced reverse flow prevention devices receive financial subsidies and priority access to the grid. Conversely, projects that violate regulations may face penalties based on the magnitude of reverse flow, and repeated violations could lead to suspension of grid access and inclusion in a dishonesty list. In light of current policy trends, distributed reverse flow prevention devices not only meet increasingly stringent grid access standards but also enhance the economic and social benefits of distributed PV systems, making them essential for promoting the efficient use of clean energy.

Innovative Safety Technology: Empowering Smart Control with New Strategies

Guoneng Rixin’s self-developed distributed PV reverse power flow control device eliminates the need for manual operation to prevent reverse flow. The device automatically activates a regulation mechanism before reverse power occurs, allowing it to monitor the dynamic changes in both PV generation and electricity load in real time. Based on the power fluctuations at various monitoring points, it automatically adjusts the output power of the PV system, achieving smooth regulation and intelligent control. This significantly reduces the frequency of operations on the grid connection switch, enhancing the stability and reliability of the power plant.
