“…Power systems likely face with the condition that one, two, or more components are out of service. Dealing with power system assessments in contingency conditions is hence crucial for the system operators [5,27]. Note as well that since the higher order of contingencies are of trivial probabilities, usually single and double outage contingencies are merely accounted for in system studies.…”

This paper reveals that the existing techniques have some deficiencies in the proper estimation of voltage stability margin (VSM) when applied to a power system with different load change scenarios. The problem gets worse when credible contingencies occur. This paper proposes a real-time wide-area approach to estimate VSM of power systems with different possible load change scenarios under normal and contingency operating conditions. The new method is based on an artificial neural network (ANN) whose inputs are bus voltage phasors captured by phasor measurement units (PMUs) and rates of change of active power loads. A new input feature is also accommodated to overcome the inability of trained ANN in prediction of VSM under N-1 and N-2 contingencies. With a new algorithm, the number of contingencies is reduced for the effective training of ANN. Robustness of the proposed technique is assured through adding a random noise to input variables. To deal with systems with a limited number of PMUs, a search algorithm is accomplished to identify the optimal placement of PMUs. The proposed method is examined on the IEEE 6-bus and the New England 39-bus test system. Results show that the VSM could be predicted with less than 1% error.

“…To eliminate the inter-area modes and furthermore, to increase the overall stability of the system, the concept of Wide Area Control (WAC) has emerged. The wide area controller aims to utilize the synchronized measurements in order to develop suitable coordination signals which enhance the damping performance of the generators' local controllers in compensating effectively local and inter-area oscillations [3], [4]. The availability of synchronized measurements, through the Phasor Measurement Units (PMUs), is crucial for the WAC operation, since the observation of inter-area oscillations is only possible through their utilization.…”

Wide Area Control (WAC) of power systems is highly depended on synchronized measurements provided by the Phasor Measurement Units (PMUs). However, the contemporary measurement chain and the communication network are far from ideal. Therefore, it is essential to identify the impact of the availability and quality of the synchronized measurements, on the wide area controller's performance. This paper examines the effect of measurement errors and delays/dropouts on the damping capability of the wide area controller. The measurement errors considered in this work are according to the dynamic compliance requirements of the PMU during disturbances as it is imposed in the IEEE Synchrophasor Standard C37.118.1-2011. The delays are separated into measurement and feedback delays. The results indicate that delays along with dropouts deteriorate significantly the WAC performance, while the consideration of only the measurement errors (steady-state and dynamic) in the simulation environment has a minor effect on its operation. For this reason, a linear predictor is proposed to compensate effectively and timely all the system's delays. The case studies are conducted on the IEEE 39-bus system and evaluated through the Prony analysis tool.
