VoltageSensitivity

class popo.network.VoltageSensitivity(name, base_multiplier, step_multiplier, min_voltage_base_pu, min_voltage_step_pu, active_base_kw, active_step_kw, reactive_base_kvar, sensitivity_pu_per_mw)

Bases: object

How far the worst bus voltage moves per unit of substation demand.

Variables:

• name – Circuit name.

• base_multiplier – Load multiplier of the reference solve.

• step_multiplier – Load multiplier of the perturbed solve.

• min_voltage_base_pu – Worst energised bus voltage at the reference.

• min_voltage_step_pu – Worst energised bus voltage under perturbation.

• active_base_kw – Substation active power at the reference.

• active_step_kw – Substation active power under perturbation.

• reactive_base_kvar – Substation reactive power at the reference.

• sensitivity_pu_per_mw – Voltage drop per megawatt at the substation. A stiff network has a small value and a weak one a large value.

property power_factor_ratio: float

Reactive to active power at the reference solve.

property voltage_drop_percent: float

Worst-bus drop below nominal under perturbation, in per cent.
