Experimental Determination of Static Load Characteristics in Nodes of Distribution and Backbone Networks

A new algorithm for processing experimental data is proposed that is based on the isolation of the load response to voltage changes from the entire volume of experimental data. At each iteration step, a system of linear equations is compiled in which the number of equations is greater than the number of unknowns. The solution of the system is performed by the method of pseudo-inverse matrices. The algorithm has been tested on a model of “experimental” data generated at a given static load characteristic. Further restoration of the coefficients of the static characteristic of the load showed the rapid convergence of the algorithm to the true values of the coefficients. The algorithm is used to process data from an active experiment conducted in a 110-kV network node.
