four_quadrant_control_mode – Mode inverter is operating in when inverter_type is FOUR_QUADRANT.

## Synopsis

module generators; class inverter { enumeration {} four_quadrant_control_mode; } object inverter { four_quadrant_control_modevalue; }

## Remarks

The value for four_quadrant_control_mode determines the value at which VA_Out is set.

### NONE

The value for VA_Out is left as the result of its initial calculation using VA_In, efficiency, and losses.

### CONSTANT_PQ

The value for VA_Out is comprised of the values for P_Out and Q_Out.

### CONSTANT_PF

The value for VA_Out is calculated such that the value for power_factor remains constant.

### CONSTANT_V

This mode is not yet implemented.

### VOLT_VAR

This mode is not yet implemented.

### LOAD_FOLLOWING

The output of the inverter is based on the real power defined by the `sense_object`, seeking to shave the peaks and fill the valleys by modulating its own power output. The parameters for this control mode assume an energy storage device is attached to the inverter.

### VOLTAGE_SOURCE

The inverter is acting as a voltage source with two modes available, isochronous mode and droop mode.

## Default

The default value for four_quadrant_control_mode is NONE.
