COUPLING_COEFFICIENT

Positive coupling magnitude for this device within its coupling group. The scheduler couples the power flows of all devices in the group: each device’s power is its coupling coefficient times the group’s common flow level. The flow direction of each device is inferred from which directional capacity is set: a device given only a production-capacity is an output (producing) device, and a device given only a consumption-capacity is an input (consuming) device. The unspecified direction is assumed to be zero (mirroring how a missing directional site capacity defaults to zero), so there is no need to set the opposite direction to a fixed 0 (though setting it explicitly still works). For example, a CHP unit with 50% thermal and 30% electrical efficiency uses a gas input device (coefficient 1), a heat output device (coefficient 0.5) and an electricity output device (coefficient 0.3). Defaults to 1.
