First Solar monitors one of the largest databases of utility-scale PV installations in operation today. We have engineered a proprietary plant control system and incorporated forecasting and energy scheduling capabilities to ensure bulk power reliability and stable grid integration—this functionality is operational today on PV plants that are several-hundred megawatts in size.
First Solar’s plant control system receives real-time data from the plant Supervisory Control and Data Acquisition (SCADA) system and analyzes the performance of each inverter. It checks the grid requirements and set points by the grid operator or remote operations center and sends individual instructions to each inverter ten times per second based on its location within the plant, losses and historical data. This ensures the plant adheres to its voltage, frequency and power output requirements.
