Grid-Connected Inverter System
Ride through is the capability of a grid-connected inverter to stick transiently stable and remain interconnected with the utility grid without disconnecting for a definite time during grid
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
Solar inverters connect to the grid through a process known as grid synchronization, which involves aligning the inverter's output voltage, frequency, and phase with the grid's parameters. Once synchronization is achieved, the inverter closes its output contactors, allowing bidirectional power flow between the solar power system and the grid.
However, the seamless integration of solar energy into the existing electrical grid requires precise synchronization between the solar inverter and the grid itself. Grid synchronization in solar energy is the process of aligning a solar inverter's output with the grid's voltage, frequency, and phase, enabling safe and efficient power transfer.
Grid Support Functionality: Solar inverters with grid support functionalities, such as F-W control and VSG emulation, can enhance grid stability and resilience by actively participating in grid frequency regulation and voltage control, reducing the likelihood of synchronization delays.
