The evolutionary optimization approach for voltage profile estimation in a radial distribution network with a decreased number of measurements

The procedure for estimation of voltage profile in a radial distribution network considering decreased number of measurements is presented in the text. The proposed procedure is based on hypothesis that feeder voltage profile in case of the limited number of feeder measurements can be successfully estimated using evolutionary optimization approach. The procedure consists of two main steps. In the first step, the location of the voltage measurements are determined with aim to have as small as possible the number of the locations. This is done by applying the analytical mathematical procedure. After the measurement locations are defined, in the second procedure step the optimization aims to estimate whole voltage profile is performed employing the evolutionary algorithm. The proposed procedure is tested on two test radial distribution feeders to verify the proposed procedure.
