Iterative compensation algorithm for electrical distribution system analysis

In this paper, components models and analysis algorithm to analyze a large-scale electrical distribution system is proposed. The component models described here include conductor, shunt capacitor/reactor, transformer, cogenerator and load. To solve the network equations, sparse programming techniques is introduced, and the superposition of injected current sources and an iterative voltage compensation method is introduced for solving algorithm. Proposed models are presented by phase frame representation, different from the conventional application of symmetrical frame representation. The proposed techniques were applied to a practical distribution system to show that the technique is applicable to a large-scale problem such as several hundreds bus system and also to show the possibility of real time application.
