Adaptive Voltage Regulation Scheme for Improved Power Management in Metropolitan

Abstract

The problem of voltage regulation in metropolitan cities has been well studied. There exist different models to handle this problem, which consider the available voltage and number of connections in the part of city as the key in voltage regulation. However, the methods suffer to achieve higher performance in voltage regulation. To handle this issue, an Adaptive Voltage Regulation Scheme (AVRS) is presented in this article. The proposed method considers the number of high load connections, number of low load connections, no of commercial connections, no of household connections and so on. Based on the connection details, the method categorizes the micro grids into two categories like commercial support grid and household support grid. Based on the category of the grid identified, the method computes the Adaptive Voltage Rate (AVR) for various grids, which represent the voltage to be regulated for the grid at particular time. The AVRS scheme performs voltage regulation according to the value of AVR. This process is iterated at different time stamp of a day. This will be analyzed in different times like business hours and normal hours. Based on the AVR measured, the method performs voltage regulation and produces higher performance.
