%X The renewable energy systems (RESs) are an attractive option to electrify the community as they are environment friendly, free of cost, and all-pervading. The efficiency of these energy systems is very low and can be improved by integrating them in parallel. In this paper, hydro (7.5£¿kW) and solar systems (10£¿kW) are taken as RESs and connected with the utility grid. Due to the intermittent nature of both the hydro and photovoltaic energy sources, utility grid is connected to the system for ensuring the continuous power flow. The hydro power generation system uses the self excited induction generator (SEIG) and converters. The AC/DC/AC converter is used as interface to connect the hydro turbine to the utility grid to adjust the generated voltage to the utility grid voltage. The solar generation system is the combination of PV array, boost converter, and solar inverter. The control of both the hydro and solar power plants is provided through the constant current controller. The analysis has been done to verify the existence of the proposed system. Results demonstrate that the proposed system is able to be put into service and can feed the community. 1. Introduction Electricity requirement is increasing day by day all over the world. The power generation of electrical energy to fulfill the power requirement is mainly done with the use of fossil fuels such as oil, coal, and gas. The conventional scheme of power generation may cause depletion of the fossil fuel and degradation of environment. Because of this, the researchers are envisaging the power generation technique from the renewable energy sources such as solar, hydro, wind, and biomass. These energy sources are most efficient to be preferred for distribution generation (DG) system as they are abundantly, economically, and easily available. Such types of DGs have less cost with easy and less expensive maintenance [1]. Recently, solar systems are seeking more attention as solar energy is omnipresent, and cost of photovoltaic (PV) cell is reducing nowadays. The PV systems are intermittent in nature and cannot satisfy the power requirement alone throughout the year. Hence, mostly the grid integrated PV system with advancement is preferred to ensure the continuous power flow [2¨C8]. The mini/micro hydro systems are also getting interest to generate the electrical power in remote/rural areas. The standalone hydro system with smaller sizes uses self-excited induction generator (SEIG). The SEIG is maintenance free, rugged in construction, has good conversion efficiency, and is self-protected against fault
