Optimal sizing and operational strategy of PV and micro-hydro

The optimal configuration of hybrid renewable energy (RE) system is useful for ensuring enough power is generated to meet the demand with reliable and cost effective manner. This is an alternative environmental friendly approach to reduce the use of diesel generators and cost of power generation. It is also a step to support the government´s intention to move towards green energy. In this paper, the hybrid of micro-hydro, solar, diesel generator, power converter and battery as back-up supply are the basic components considered in the optimal sizing and operation of hybrid RE system. Based on the domestic load at Kampung Pasir Raja, Dungun, the proposed hybrid RE system is determined and analyzed by using the Hybrid Optimization Model for Electrical Renewables (HOMER) software. This paper discusses thoroughly on the best combination of hybrid RE system determined based on the lowest Total Net Present Cost (TNPC). Furthermore, the results have shown that the TNPC produced by the hybrid RE system is better than the conventional energy that is the diesel generator.
