SIMULATION AND MODELING OF INTEGRATED RENEWABLE ENERGY RESOURCES (HYDRO, SOLAR AND WIND ENERGY)

Renewable energy sources are likely to become prominent in the future due to less environmental impact and energy cost escalation. However, due to its intermittent essence, it encourages us to integrate various renewable energy resources to improve the reliability and quality of power supply to the consumer. Henceforth, this paper emphasizes the integration of various renewable energy sources (RES) such as - photovoltaic (PV), wind energy (WE) and hydro-electric grid (HEG) systems through software simulation. The purpose of this research was to compare the end user power quality and reliability between isolated mode and integrated mode operation of the power system through the result analysis in MATLAB simulation. In this qualitative study, the required data on wind and solar of a particular place, Samdrup Jongkhar (Bhutan) were collected in the form of satellite recorded data (NASA and SolarGIS). The result from this study highlights the nature of energy output from isolated-mode operated power plants and integrated power plant systems. From the result analysis, it has been shown that the quality and reliability of energy output from an integrated power system is much higher as compared to the isolated-mode operated power plant.
