Grid parameter estimation procedure for emerging countries scenario

One of the main problems in the power system sector in emerging countries is lack of public data and information about transmission and distribution grids: quite often, the only source is limited to the map of the network and general information on the voltage profile and power flows in the lines. Hence, it is currently hardly impossible to perform further network analysis. To overcome this, the paper introduces a reverse engineering procedure applied to the estimation of system parameters, given incomplete information typically available on power flows. To check the accuracy of the proposed model, a power flow solution with the estimated parameters is used as benchmark. Results of the procedure are presented with reference to the transmission network of Tanzania.
