Renewable energy utilization is widely concerned all over the world. They are increasingly utilized in Thailand due to the Royal Thai government policy and subsidize that emphasize their utilization in potential areas. Chaiyaphum Province, located in northeastern part of Thailand, is a high potential area for renewable energy utilization. This paper presents the feasibility study of the potential of hybrid renewable energy sources, i.e. solar and wind energies, for the rural community under Chaiyaphum Provincial Organization. In this study, annual data of wind speed, wind direction, wind gust speed and solar irradiation taken from the meteorological department of Chaiyaphum provincial area, Thailand were used in the study. Optimum hybrid renewable energy generation sources, i.e. wind turbine and PV, were designed for Nongplathao Park Community, Muang District, Chaiyaphum province. Results showed the annual average wind speed of 7.02 m/s, and annual average solar energy of 4.6722 kWh/m 2 . Furthermore, the design of On-Grid hybrid renewable generation system was seen to be practical. Initial investment cost was analyzed by Homer Version 3.6.3.0. From the results, the total capacity for generation of electricity from hybrid renewable energy sources of 52 kW was obtained. By considering the community location and its potential, small wind turbines with a capacity of 3 kW/tower, 4 units and PV system of 40 kW were chosen for design in this study..

Abstract-Hybrid renewable energy began to play an essential role after the fossil energy is gradually reduced. In Thailand, the government is very interested in renewable energy, and there are many potential areas in countries where renewable energy sources such as wind energy and solar energy are available. This paper presents the study results of the optimal design of hybrid renewable energy generation sources integrated with battery storage system in a case study of Nongplathao Park, Chaiyaphum Provincial Administration Organization in Thailand. In this study, the On-Grid and the Off-Grid hybrid renewable generation systems were designed, and Homer version 3.11.2 software was used as an analytical tool. The simulation results show that On-Grid renewable energies system can produce electricity supplied to the load and there is also electricity that is sold to the system. The Off-Grid system used renewable energy sources to generate power integrating with the energy storage system for supply electricity to the selection area. Although, an Off-Grid system has expensive installation costs, in the future there is a tendency for lower system equipment costs. This simulation can be used as a case study to promote to other appropriate areas.
