Intelligent Approach for Distribution System Load Estimation

The operation of distribution systems requires a rather high number of planned or forced switching operations. In order to prepare them, it is necessary to estimate loads at different levels in the system. This paper proposes a load estimation method for distribution systems with weighted least square estimation and back propagation artificial neural network. The above methods are demonstrated with IEEE 14 bus distribution system with comparison of simulated estimated outputs. The purpose of the load estimation method presented in this paper is the economic and efficient use of the available remote measurements in the distribution system considering typical measurements from the past and knowledge of load composition and load behavior at the distribution transformers´ level.
