Distribution System State Estimation Algorithm

Abstract

=============================================================================================== Distribution System State Estimation Milad Izadi, Mohammad Farajollahi, and Hamed Mohsenian-Rad University of California, Riverside July 2019 =============================================================================================== MATLAB [V_est] = DSSE_UCR(loc_pmu,loc_linesensor,ErrV,ErrI,ErrS)

Input Arguments: 1) Location of micro-PMUs and line sensros; 2) Standard deviation of micro_PMUs, line sensor, and psuedo-measurement; 3) Network data including load data (available at loadata.mat) and branch data (available at Ybus.mat,Yfbrn.mat, and Ytbrn.mat).

Output Arguments: Complex estimated voltage at all nodes

Use the following MATLAB codes and sample input data to call the DSSE_UCR function (a test code is provided in Test_DSSE_UCR.mfile):

loc_pmu = [1,12,28]; % Location of micro-PMU loc_linesensor = [ 18 22 7 30 15]; % Location of line sensor ErrV = 1; ErrI = 1; ErrS = 25; % Standard deviation [V_est] = DSSE_UCR(loc_pmu,loc_linesensor,ErrV,ErrI,ErrS)
