Three-Phase Power Flow Dataset for the Brazilian PAI14 Distribution Feeder (Araraquara)

Repository Description This document describes the columns and data structure of each file used to model the real Brazilian distribution feeder analyzed in the associated research article. The dataset contains the input data required to reproduce the feeder model and the simulations presented in the paper "Fast and Scalable Three-Phase Voltage Sensitivity Method for Unbalanced Distribution Networks", submitted to IEEE Access. Support and questions: [e-mail] Data Files Description The dataset is organized into several files describing the electrical components of the distribution system, including buses, branches, transformers, switches, generators, and base values. DATA_BUS.DAD This file contains the bus data of the distribution network. nBusID Area phases ID_Real DESCRICAO Type Z I P Vnom Connection VLN(a)[pu] Deg(a)[deg] VLN(b)[pu] Deg(b)[deg] VLN(c)[pu] Deg(c)[deg] Pd(a)[kW] Qd(a)[kVAr] Pd(b)[kW] Qd(b)[kVAr] Pd(c)[kW] Qd(c)[kVAr] Vmin[pu] Vmax[pu] VnomNominal voltage of the load model in per-unit. Type 0 - Slack1 - PQ2 - PV ZIP Load Model The parameters Z, I, and P represent the relative participation of each component in the ZIP load model. For a constant power load (PQ model): Z = 0I = 0P = 1 Any combination is allowed provided that: Z + I + P = 1 Connection 0 - Y (Wye)1 - D (Delta) Phases The phases field indicates the phases where the loads are connected. 100 - A010 - B001 - C110 - AB011 - BC101 - AC111 - ABC DATA_BRANCH.DAD This file describes all branch elements of the system, including lines, transformers, shunt elements, voltage regulators, and switches. nBranchID Area phases bus_from bus_to Type ampacity(A) ampacity(B) ampacity(C) raa xaa rba xba rbb xbb rca xca rcb xcb rcc xcc yaa yba ybb yca ycb ycc NOTE:All impedance parameters Zabc must be inserted in Ohms.
