Summary:Recently, there has been a tendency to use vector measuring devices to update the equivalent. In these approaches, vector measurements are used to tune the parameters of the equivalent, rather than the primary definition. This article proposes a new approach to defining the equivalent as a black box. The structure of the equivalent is determined depending on the number of border branches. Power inputs are connected to each boundary branch, which are equivalent peaks, which are connected to each other according to the principle each with each through resistance and an ideal transformer to take into account the possible voltage classes of each of the equivalent peaks. The equivalent parameters are determined using optimization methods, and the objective function is the deviation error of the flows along the boundary branches in the model from the flows along the boundary branches taken using vector measuring devices.
