Smart Power Control System (AGC/AVC)
The intelligent power control system is primarily used to regulate the active power output and voltage control of the power system, in response to changes in grid load and frequency, maintain voltage within an appropriate range, thereby ensuring grid stability and frequency control, and guaranteeing power supply quality and the normal operation of equipment.
Control flow:
The intelligent power control system features automatic power adjustment using a cyclic scanning approach. It continuously scans in real time the differences between each control target variable at the new-energy power station and the scheduled reference curve or the real-time command values. Based on these real-time comparisons, the system intelligently generates an optimal set of adjustment strategies and transmits adjustment commands over the network, thereby achieving dynamic tracking and adjustment of the power station.
Automatic Generation Control (AGC) mode for active power
Inverter Active Power Control
Based on the inverter’s economic operating range, the active power setpoint of the inverter is adjusted remotely to either the lower or upper limit of its economic operating range, thereby avoiding complete shutdown of primary equipment, accelerating the adjustment rate, and achieving the desired active power regulation.
Start/Stop Inverter Control
By means of remote adjustment, one or more inverters can be started or stopped to achieve the purpose of active power control and regulation.
Automatic Voltage and Reactive Power Control (AVC) mode
Reactive power output of the inverter
By leveraging the inverter’s inherent reactive power output characteristics and employing a system control strategy to adjust the reactive power output of all or part of the inverters in the entire photovoltaic power plant, we can stabilize the grid connection point voltage and ensure the stable operation of the photovoltaic power plant.
This mode does not require the construction of SVG/AVC, saving substantial investment funds and eliminating the need for associated maintenance costs.
Operating Mode Selection
Constant reactive power at the grid connection point
Grid connection rated voltage
Constant power factor at the grid connection point
By adjusting the options via software control panels, you can select either the constant reactive power mode or the constant voltage mode at the grid connection point. The control software then collects real-time data from the grid connection point and compares it with the target values to determine the compensation adjustments. Taking into full account the operational status of all equipment in the photovoltaic power plant, the system performs strategic calculations and transmits the adjustment parameters to each participating inverter, thereby ensuring that the grid connection point parameters remain stable near the target values.
