Simulation technique for voltage stability Analysis and contingency ranking in power systems
Voltage instability is one phenomenon that could happen in power system due to its stressed condition. The result would be the occurrence of voltage collapse which leads to total blackout to the whole system. Therefore voltage collapse prediction is important in power system planning and operation. Line outage in power system could also lead to the event of voltage collapse which implies the co...
متن کاملA Novel Index for Online Voltage Stability Assessment Based on Correlation Characteristic of Voltage Profiles
Abstract: Voltage instability is a major threat for security of power systems. Preserving voltage security margin at a certain limit is a vital requirement for today’s power systems. Assessment of voltage security margin is a challenging task demanding sophisticated indices. In this paper, for the purpose of on line voltage security assessment a new index based on the correlation characteristic...
متن کاملThree Dimensional Visualizations for Power System Contingency Analysis Voltage Data
Contingency analysis (CA) as an inherent function of system security assessment is critical for detecting underlying problems in a power system. More frequent CA computation is required in the deregulated power markets to monitor the state of the system under “what if” situations in view of the fact that the power systems are now operated closer to their limits imposed by the increasing number ...
متن کاملA Simple Extension of Stability Feature Selection
Stability selection [9] is a general principle for performing feature selection. It functions as a meta-layer on top of a “baseline” feature selection method, and consists in repeatedly applying the baseline to random data subsamples of half-size, and finally outputting the features with selection frequency larger than a fixed threshold. In the present work, we suggest and study a simple extens...
متن کاملImproving Voltage Stability Margin Using Voltage Profile and Sensitivity Analysis by Neural Network
This paper presents a new approach for estimating and improving voltage stability margin from phase and magnitude profile of bus voltages using sensitivity analysis of Voltage Stability Assessment Neural Network (VSANN). Bus voltage profile contains useful information about system stability margin including the effect of load-generation, line outage and reactive power compensation so, it is ad...
