A Novel Approach of Voltage Sag Data Analysis Stochastically: Study, Representation, and Detection of Region of Vulnerability

A voltage sag is a major power quality problem at any load location, mainly due to short circuit faults. Its effects are especially clear in the industrial sector because they lead direct financial losses. The first and most important step getting rid of or least reducing find places network where it can happen. So, this article discusses creative way weak spots more likely drop. This innovative strategy based on correlation stochastic normal probability distribution. evaluated using an analytical method. method simulates number, type, location faults randomly throughout system. After gathering dip data, analyzed distribution concepts. concept provides relationship between frequency other parameters, occurrence area was indicated by that, region vulnerability (ROV) developed ROV flow chart. paper uses IEEE 30-bus RTS system as case study demonstrate usefulness suggested MATLAB software.
