Fault ride-through capability

Definition

Fault ride-through capability refers to the ability of a power generation system, such as concentrated solar power (CSP), to remain connected to the electrical grid during short-term voltage sags or disturbances. This capability is crucial for maintaining grid stability and reliability, as it allows the system to withstand faults without disconnecting from the grid, thereby helping to prevent cascading failures and ensuring a continuous supply of electricity.
