Abstract

This research presents the design and simulation of a hybrid microgrid system for the Takht Bhai region of Mardan, Pakistan, integrating floating photovoltaic (FPV), small-scale hydro, and wind energy resources. The proposed system was modeled in DIgSILENT PowerFactory using a 38-bus distribution network to evaluate load flow, voltage stability, short-circuit performance, and power quality. Simulation results showed that the voltage at the point of common coupling remained stable at approximately 1.06 p.u. under normal operating conditions. During a 50 ms short-circuit event, the POC_BUS voltage dropped to 0 p.u. and recovered immediately to 1.06 p.u. after fault clearance, indicating strong fault ride-through capability. The 132 kV POC_BUS recorded a three-phase maximum short-circuit current of 14.09 kA and a peak current of 34.77 kA, while the minimum three-phase fault current was 12.07 kA. At the 0.4 kV inverter bus level, three-phase maximum fault currents ranged from 3.46 to 3.81 kA, whereas the 33 kV collection level showed fault currents of up to 51.75 kA. Power quality assessment based on the P28 Engineering Recommendation confirmed acceptable voltage fluctuation and flicker performance. The results demonstrate that the coordinated use of hydro, FPV, and wind resources improves voltage regulation, enhances system reliability, and provides a technically feasible renewable energy solution for rural electrification.
