A Hybrid Method for Load flow Calculation based on LVDC Power Distribution Networks

Abstract

Low voltage direct current (LVDC) distribution system stability, supply security and power quality are evaluated by computational modelling and measurements on an LVDC research platform. Computational models for the LVDC organize investigation are created. The LVDC arrange control misfortune model is produced in a MATLAB domain and is prepared to do quick estimation of the system and segment influence misfortunes. The model integrates analytical equations that describe the power loss mechanism of the network components with power flow calculations. For an LVDC network research platform, a monitoring and control software solution is developed. The solution is used to deliver measurement data for verification of the developed models and analysis of the modelling results. In the work, the power loss mechanism of the LVDC network components and its main dependencies based on hybrid method is described. Energy loss distribution of the LVDC network components is presented.
