Assessment of Voltage and Frequency in Islanded Microgrids by Varying Load Parameters Using Modified Gauss-Seidel Power Flow

Power flow studies play a crucial role in the planning and expansion of power systems, particularly with the increasing integration of distributed generation (DG) and the emergence of micro-grids. Micro-grids, which are localised power systems with their own generation and load, have become an attractive option for enhancing the resilience and efficiency of electric supply. The effect of load parameters in conjugation with the Modified Newton Raphson (MNR) power flow has been investigated in this paper. To validate the effectiveness of the proposed method, the MNR algorithm has been implemented and tested on a 6-bus islanded microgrid test bus system. This test system serves as a representative model for evaluating the performance and capabilities of the MNR method in solving power flow analysis for islanded micro-grids.
