Item Power Flow Analysis of Power Distribution System Integrated with Solar Photovoltaic Based Distributed Generation(Institute of Electrical and Electronics Engineers Inc., 2022) Saw, S.K.; Navada, H.G.; Shubhanga, K.N.In this paper, a Power Flow (PF) algorithm for a Power Distribution System (DS) derived from the conventional backward-forward sweep method is simulated with the integration of Solar Photovoltaic (SPV) based distributed generation. This integration algorithm is based on the load current injection, where the SPV generation is modeled as a negative load injection at one of the nodes of the DS. In this method, the PF solution is obtained by executing both the sweeps in a single step through a Load Current to Bus Voltage (LCBV) matrix. The SPV system is integrated considering an additional inverter node connected to one of the nodes of DS through the SPV interfacing elements. Based on the control specification at the inverter node, it may operate either in PV or PQ mode. The SPV inverter node voltage is computed using an alternate-iterative method in a separate algorithm. The effectiveness of the modified PF algorithm is verified on the balanced DS, considering diverse test systems (IEEE-33 node, IEEE-69 node DS). The qualitative aspects of the algorithm are analyzed and compared with the existing conventional technique. © 2022 IEEE.
