APPARATUS AND METHOD OF POWER FLOW CALCULATION OF BIPOLAR DC DISTRIBUTION SYSTEM CONSIDERING THE LOAD UNBALANCE

摘要

The present invention is a method for calculating a power current of an unbalanced bipolar DC distribution system, comprising: setting an initial voltage value of a bus; Calculating a current value by measuring a power value and a voltage value from a load or power generation element connected to the bus through a node; Generating a Y-Matrix vector consisting of an n-th current matrix, an n-th voltage matrix, and a conductance matrix based on the calculated current value; Rearranging the Y-Matrix vector when the power value measured from the load or power generation element is less than or equal to the maximum power value; And repeating the process of rearranging the Y-Matrix vector until a difference between the n+1th voltage matrix and the nth voltage matrix of the rearranged Y-Matrix vector becomes less than a predetermined value.
