As the adoption of solar energy continues to rise, the role of solar power inverters becomes increasingly critical, especially regarding their ability to support the electrical grid. One important feature of modern solar inverters is grid support, which enhances the stability and reliability of the power supply. In this blog, we’ll explore what grid support means for solar inverters and highlight the capabilities of Sungrow’s 6.25/6.8 MVA MV Turnkey Station.
What Does Grid Support Mean for a Solar Power Inverter?
Grid support refers to the ability of a solar power inverter to assist in maintaining the stability and reliability of the electrical grid. As more renewable energy sources are integrated into the grid, managing fluctuations in power generation and consumption becomes essential. Here are some key aspects of grid support:
- Compliance with Standards
To ensure safe and effective operation, solar inverters must comply with certain international standards. For instance, compliance with IEC 61727 and IEC 62116 is crucial for grid-connected systems. These standards dictate how inverters should behave under various conditions, ensuring they can contribute positively to grid stability.
- Reactive and Active Power Control
Grid support involves the management of both reactive and active power:
– Active Power Control: This allows the inverter to adjust its output in response to grid demands, helping to balance supply and demand.
– Reactive Power Control: This is essential for maintaining voltage levels within the grid. By supplying or absorbing reactive power, the inverter helps stabilize voltage fluctuations, which can occur due to changes in load or generation.
- Ride-Through Capabilities
Inverters with ride-through capabilities can maintain operation during disturbances in the grid, such as voltage sags or frequency fluctuations. The following ride-through features are essential:
– Low Voltage Ride Through (LVRT): This capability ensures that the inverter remains operational during short-term voltage dips, helping to prevent blackouts.
– High Voltage Ride Through (HVRT): Conversely, HVRT enables the inverter to stay connected during voltage spikes, protecting both the inverter and the grid.
– Frequency Ride Through (FRT): This feature allows the inverter to continue functioning during frequency disturbances, contributing to overall grid stability.
