Optimum Scheduling of Isolated Hybrid Renewable Energy System - A Case Study using HOMER

Abstract

Ravita Saraswat and Sathans S

This paper compares the different scheduling scenarios of hybrid renewable energy system in terms of system configuration, economy, power production, biomass availability and pollutant emission. The hybrid renewable energy system comprises the solar, wind and biomass based power generating systems. This case study is carried out for a specific geographical location (village Ramgarh) in Ambala district of Haryana state, in India. The HOMER software tool is used to carry out simulations of three different scenarios viz. Generator is on or off depending on the availability of solar and wind power; the generator is on for all time; and the generator operation is optimized. Sensitivity analysis is also carried out for different maximum annual capacity storage in relation to change in net present cost (NPC) and levelized cost of energy (LCOE). The results of the analysis indicate that as the maximum annual capacity storage increases, the net present cost and levelized cost of energy decreases. The comparison of the results is presented in a tabular form.
