%X Simulation and modeling of standalone DC linked hydro/PV/battery hybrid energy system (HES) and power management strategy (PMS) for identifying the active power sharing have been done. The performance analysis of the proposed HES and its power management strategy has been done using the simulink toolboxes of MATLAB software. The proposed system consists of 10£¿kW PV system, 7.5£¿kW hydro system, battery, and power condition unit. In some remote/rural areas, it is very difficult to satisfy the demand of electrical power throughout the year with the power grid. In such areas, the power requirement can be fulfilled by renewable energy system such as hydro or PV system. Either the hydro system or PV system is not capable of supplying power requirement throughout the year as both systems are intermittent. Hence, the judicious combination of hydro and PV system has been modeled for electrification. The power management strategy is modeled to manage the power flow of the energy systems and battery to fulfill the load demand. The presented results clearly show that the proposed HES and its control strategy are suitable for implementation in remote/rural areas. 1. Introduction Electrification of remote/isolated areas (where grid accessibility is not possible) may be possible by harnessing the renewable energy sources presented in the particular areas. Among these renewable energy sources, hydro and solar energy sources are more promising for electricity generation. The hydro and PV system are gaining the momentum of researchers for electrification in remote/rural areas. Either standalone hydro system or PV system is not sufficient to fulfill the power requirement throughout the year. Therefore, for getting the optimal results by combining the advantages of hydro and solar energy sources, PV/hydro hybrid system has been analyzed and also installed [1¨C3]. The geographical and climatic condition affects the performance of the hybrid system. Therefore, a backup is necessary in the case when one of the energy sources is not available or the power generated by the hybrid system is not capable of fulfilling the power demand. To ensure the continuous power supply and to take care of intermittent nature of energy systems, diesel generator can be integrated to overcome the problem [4, 5]. Economic analysis and cost optimization of such system have been done to ensure the existence of the system [6, 7]. The additions of diesel generator are advantageous over the pure renewable energy system but also have some major problems such as diesel generator needs fossil fuel and
