The study of power flow analysis for microgrids has gained importance where several methods have been proposed to solve these problems. However, these schemes are complicated and not easy to implement due to the absence of a slack bus as well as the dependence of the power on frequency as a result of the droop characteristics. This paper proposes simple and effective modifications to the conventional method (Newton Raphson) to compute the power flow for microgrids. The presented method provides a simple, easy to implement, and accurate approach to solve the power flow equations for microgrids. The proposed method is applied to two test systems: a 6-bus system and a 38-bus system. The results are compared against simulation results from PSCAD/EMTDC which validate the effectiveness of the developed method. The proposed technique can be easily integrated in current commercially available power system software and can be applied for power system studies. Index Terms-Distributed generation (DG), islanded microgrid, power flow.

“…According to [7,11,13], load flow or power flow is the movement of active and reactive power from generators to different load points of the system. This examination is an exceptionally basic instrument utilized by power system engineers for planning and deciding the steady-state activity of a power network.…”

The undulated power supply has dropped to its worst reliability index in most parts of the city despite the installations of distribution transformers to improve the power. In this work, examination of Port Harcourt Town Zone 4 (Z4), Rivers State power distribution system forcing on its operation, planning for future expansion of the system, and sharing of power between utilities was done. The objective was to unravel the problematic recurrent blackouts as a result high power loss, that is (I 2 R) in the line; low voltage profile, poor cos∅ at the load end, excessive loading of feeder transformers, and conductors rating inadequacy at the receiving end of the 33KV Distribution part of the substation. A comprehensive study was carried out on the system with the formation of node admittance matrix. Programmable codes were written using MATLAB script to resolve the static power flow equations defined applying Fast decoupled-Newton Raphson calculation procedure centered on the advantages of time and PC memory space (PC-MS). Thus, the node voltage and the other variables like branch flows and phase angles were gotten, and network losses were reduced. However, the results obtained were compared with that gotten from Electrical Transient Analyzer Program (ETAP) application software. It was seen that the two results got were related. The general net power gotten was (129.741 MW, 83.818 MVAr) applying the Fast Decoupled-Newton-Raphson load flow technique in MATLAB programming environment after the addition of receptive power through the means of the capacitor bank to the affected nodes. The total net power that is real and reactive got employing ETAP programming were (125.765 MW, 92.782 MVAr). The overall line losses were enhanced by 0.246 reductions. That is from (4.75MW, 10.05MVAr) to (3.58MW, 7.57MVAr) of the entire real power losses.

“…As per the guideline provided in the IEEE standard 1547.7 for islanded MG, generally, output impedance is assumed to be inductive [37]. Therefore, droop characteristics represented by (1) and (2) are considered in this paper. Nonetheless, the DG's output impedance may become resistive due to the existence of highly resistive network and/or because of the nonexistence of the coupling inductor at the output of the converter.…”
