Method for determining of voltage steady-state load characteristics with subject to the limitation on sensitive parameters and electrical safety of active experiment

This article proposes a new approach to the processing of the active experiment results to determine the voltage steady-state load characteristics (SLC) with diverse loads in the node of the power system. The problem is that during the active experiment the composition of consumers and the desired SLC change, while the number of possible voltage control stages is limited by the operating parameters and electrical safety factors during the experiment, which significantly complicates the identification procedure of the real SLC. The paper considers the possibility of using optimization methods in solving this problem. To test the proposed method, an experiment was carried out at the laboratory installation and the efficiency of the modified method for determining the SLC is shown by its example.
