Voltage stability is always a major concern in power system operation.Recently Fault Induced Delayed Voltage Recovery (FIDVR) has gained increased attention. It is widely believed that the motor-driven loads of high efficiency, low inertia air conditioners are one of the main causes of FIDVR events.Simulation tools that assist power system operation and planning have been found insufficient to reproduce FIDVR events. This is because of their inaccurate load modeling of single-phase motor loads. Conventionally three-phase motor models have been used to represent the aggregation effect of single-phase motor load. However researchers have found that this modeling method is far from an accurate representation of single-phase induction motors.In this work a simulation method is proposed to study the precise influence of single-phase motor load in context of FIDVR. The load, as seen the transmission bus, is replaced with a detailed distribution system. Each single-phase motor in the distribution system is represented by an equipment-level model for best accuracy. This is to enable the simulation to capture stalling effects of air conditioner compressor motors as they are related to FIDVR events.The single phase motor models are compared against the traditional three phase aggregate approximation. Also different percentages of single-phase motor load are compared and analyzed.Simulation result shows that proposed method is able to reproduce FIDVR events. This method also provides a reasonable estimation of the power system voltage stability under the contingencies.ii ACKNOWLEDGEMENTS

Voltage sags is a problem affecting the electrical qualities. In this paper, effects of large induction motors on voltage sag characteristic are discussed. Moreover, the influences of different mechanical loads of the motors on voltage recovery are investigated. The study results show that reactive power contribution owing to the motor's trapped flux linkage prevents fast collapse of the voltage, resulting in non-rectangular shape of sag. The motor's negative torque induced during fault interval causes speed loss. The constant torque of mechanical load gives rise to the most speed loss, leading to a longer reacceleration and a great delay in voltage recovery.

“…It is well known that the voltage recovery after a disturbance in a power system is delayed by load dynamics (such as the dynamics of induction motors, etc. ), especially when not enough fast reacting reactive resources (dynamic VAR sources) exist [1][2][3][4][5][6][7][8][9]. The phenomenon is well known to utilities and it is typically studied either using static load flow techniques or with full scale dynamic simulations.…”

Abstract-This paper addresses the impact of load dynamics, and in particular induction motor loads, on voltage recovery after disturbances. The paper proposes a methodology that is based on load flow techniques with advanced modeling capabilities, augmented by a simplified induction motor dynamic model. The objective is to realistically capture the dynamic characteristics of voltage recovery phenomena, avoiding, however, the full scale transient simulation. The approach uses the quadratized power flow model with explicit induction motor representation. The paper describes the modeling approach and the overall methodology for evaluating the load dynamics on voltage recovery. Preliminary results of the application of the method on a simple power system with load dynamics are also included in the paper.
