Peak point detection of phase-to-phase effective voltages for smart grids: A comparative study

Abstract

Smart grid systems include many different power sources such as renewable and fossil energy basis. While collecting all type of energy on the grid, phase order, frequency, maximum voltage value and synchronization time of each power station should be known for a smooth operation of the smart grid. Therefore, the detection of peak values of grid voltages will help the smart grid operators to connect all power sources to the grid without having problems like voltage collapse, over voltage, over current and shutting down the power station. For this purpose, in an effective and efficient manner, we compare the original AMPD and the modified AMPD methods in terms of the peak point detection performance, analyze how the modified AMPD method is used for the phase-to-phase effective voltage values and show how FPGAs are able to accelerate the detection time as on-line.
