Hybrid Renewable Energy

The escalation of global energy demand has enhanced the interest on renewable energy technologies worldwide. The reliance of a single energy source has become problematic, and hybrid renewable energy technology has been identified as a feasible solution. Producing energy to limitless increasing demand is a challenging issue faced by Sri Lanka nowadays. Although, there are some studies carried out for renewable energy systems, solar-wind based hybrid renewable systems is an understudied area in Sri Lankan context. Hence, this paper aims to explore the applicability of hybrid solar-wind renewable energy generation approach for Sri Lanka. The study follows a qualitative approach with semi structured interviews from eight industrial experts, and manual content analysis technique was used for data analysis. The paper discussed the current installation practices of solar and wind technologies, applicability of hybrid solar and wind renewable energy systems and national level contribution for hybrid systems. Finally, a validated model was proposed to implement hybrid renewable energy generation systems for Sri Lanka.

The Impact

Electrification in rural areas is relatively costly compared to urban areas. Therefore, the aim of this research is to identify the best combination of hybrid renewable energy systems (HRESs) to satisfy the load demand in a sustainable and cost-efficient way. The techno-economic study of stand-alone hybrid photovoltaic–wind turbine–diesel–battery-converter energy systems based on the hybrid optimization model for electric renewable (HOMER) simulation has been analyzed for various locations in the Tamil Nadu state, India. Various combinations of the systems have been compared and analyzed based on the performance of their technical parameters, costs, the electrical power production of each source, and unmet load. The findings indicated that the off-grid solar–wind–diesel–battery configuration is the most economical for all the sites among other system configurations. Comparing with conventional diesel generators among all the locations, a combination of solar/wind/diesel/battery is the economically best design for Thoothukudi, with the least and most reliable solution in terms of net present cost and cost of energy. Also, the impact of intermittent variables becomes significant, so sensitivity analysis for the various parameters has been carried out. The study finds that the least cost of electricity and the net present cost of electricity for Thoothukudi are achieved at 0.266 $/kWh and 138,197 $, respectively. This is economical compared to a stand-alone diesel system where the obtained COE is $1.88 and the NPC is $977523. In the stand-alone diesel operating mode, 41854 kg of CO2 is produced, which is higher than CO2 emissions associated with any other renewable energy systems. According to the results, the Kanyakumari location outperforms in terms of producing environmental pollutants with emission of 1,020 kg/y CO2 at their best. Moreover, the results of the proposed study imply that the proposed renewable energy system in remote sites could be a more economical measure.
