Setting Active Power Control

Setting Active Power Control

If the PV plant has requirements of power limitation, the power grid scheduling personnel should limit the active power or disable all the active power for the PV plant, that is, to enable the active power derating mode.

  1. Choose Monitoring > SUN2000 > Running Param. > Power Adjustment. On the displayed page, check that Remote power schedule is set to Enable.
  2. Set the parameters for active power control and click Submit.

    Figure 6-42 Active power control

No Limit

Parameter

Description

Active power control mode

Set this parameter to No limit for the solar inverter to run at full load.

DI Active Scheduling

  • When setting this function, ensure that the user-defined DI port is not occupied. Otherwise, the setting will fail.
  • When setting this function, ensure that the SmartLogger is correctly connected to a ripple control receiver. (In Germany and some other European areas, a Ripple Control Receiver is used to convert a power grid scheduling signal to a dry contact signal, in which a dry contact is needed.)

Parameter

Description

Active power control mode

Set this parameter to DI active scheduling.

DI

NOTE:

DI parameters include DI1, DI2, DI3, DI4, and Percentage(%).

  • Sixteen levels are supported for the active power derating percentage.
  • "√" indicates a low level. When the four DI ports of the SmartLogger are connected, the ports are low-level ports. When not connected, the ports are high-level ports.
  • The percentage levels of DI1–DI4 should differ from each other. Otherwise, an abnormal command will be generated.
  • If the actual input DI signal is inconsistent with that configured on the WebUI, the SmartLogger controls the solar inverter to work at full load and the Abnormal Active Schedule alarm is raised.

Percentage Fixed-Value Limitation (Open Loop)

The SmartLogger provides simplified active power percentage configuration as well as power control automation, that is, to automatically adjust the active power derating percentage in different periods of a day.

Parameter

Description

Active power control mode

Set this parameter to Percentage fixed-value limitation (open loop) to control the maximum output power of the solar inverter by time segment.

Start time

If the solar inverter needs to run with specified maximum power in certain periods of a day, add setting records based on site requirements.

When multiple time points are set, the solar inverter will run with the maximum power specified for the time point that is earlier than and the closest to the current system time. For example, if you add 00:00:00 and 12:00:00 on the WebUI and the current system current is 14:30:00, the solar inverter will run with the maximum power specified for 12:00:00.

Percentage(%)

Remote Communication Scheduling

The management system or independent power adjustment device sends scheduling commands over the communications port that works with Modbus-TCP or IEC104, without the need of user configuration or operation. The SmartLogger can automatically switch between scheduling modes and send scheduling commands.

Parameter

Description

Active power control mode

Set this parameter to Remote communication scheduling.

The SmartLogger parses the scheduling command delivered by the upper-layer management system to valid instruction data that can be identified by the solar inverters in the PV plant and delivers the data to all solar inverters connected to the SmartLogger.

As the Remote communication scheduling mode has a higher priority, the SmartLogger automatically changes Active power control mode to Remote communication scheduling after receiving a scheduling command from the upper-layer management system.

Percentage(%)

The value can be Disable, Strategy 1, or Strategy 2.

  • Disable: The SmartLogger controls the solar inverter to work at full load and will not receive scheduling commands sent by the management system.
  • Strategy 1: Open-loop scheduling policy. That is, the SmartLogger evenly allocates the power value from the scheduling and delivers the average value to each solar inverter, which then operates with the specific power. The adjustment value delivered by the SmartLogger is constant. If Adjustment coefficient is set, the power value will be sent to the solar inverter after being multiplied by the preset coefficient.
  • Strategy 2: The customized function is provided for a specific power plant. Set Overshoot, Adjustment period, and Adjustment deadband based on the scheduling requirements of the power plant.

Grid connection with limited power (kW)

  • You are advised to choose Settings > Grid connection with limited power and enable the grid connection with limited power function.
  • To enable this function, you need to set power meter, inverter, and grid connection with limited power parameters. This section describes how to set grid connection with limited power parameters.
  • Before setting the parameters, ensure that a power meter has been connected to the SmartLogger.
  1. Set export limitation parameters and click Submit.

    Parameter

    Description

    Active power control mode

    Set this parameter to Grid connection with limited power (kW).

    Power meter

    Set this parameter to Smart meter. Otherwise, the function will not take effect.

    Electric meter power direction

    When the inverter has no output power, set this parameter to Positive if the active power reading of the power meter is positive. Otherwise, set this parameter to Reverse.

    Limitation mode

    • Total power: controls the total power at the grid-tied point to limit the power fed to the power grid.
    • Single-phase power: controls the power of each phase at the grid-tied point to limit the power fed to the power grid.

    Maximum grid feed-in power

    Indicates the maximum power that the inverter can feed into the power grid.

    Suggestion: Set this parameter based on the export limitation threshold allowed by the power grid company.

    Power lowering adjustment period

    Specifies the period for lowering the inverter output power.

    Maximum protection time

    Specifies the maximum duration from the time when the SmartLogger detects backflow to the time when the inverter output power reaches 0.

    Suggestion: Set this parameter based on the maximum backflow duration allowed by the power grid company.

    Power raising threshold

    Specifies the threshold for raising the inverter output power.

    Fail-safe power threshold

    Inverter output power percentage is controlled by the SmartLogger when communication between the SmartLogger and the power meter is abnormal.

    Switch-off with 0% power limit

    Specifies whether the DO port is allowed to control switch-off.

    Switch-off control port

    Set this parameter to the DO port that controls switch-off.

    Switch-on control port

    Set this parameter to the DO port that controls switch-on.

    Switch-off state feedback port

    Set this parameter to the DI port that reports the switch-off status.

    Switch-on state feedback port

    Set this parameter to the DI port that reports the switch-on status.

  2. Verify that the SmartLogger can remotely turn on and off circuit breakers in scenarios with circuit breakers.

    • Click Switch off and check that the circuit breaker is switched off properly.
    • Click Switch on and check that the circuit breaker is switched on properly.
