Optimal Distribution of Renewable Energy Systems Considering Aging and Long-Term Weather Effect in Net-Zero Energy Building Design

Abstract

<jats:p>Generation system interruptions in net-zero energy buildings (NZEBs) may result in missing the net-zero targets by a great margin. Consequently, it is significant to incorporate a realistic reliability model for renewable energy systems (RESs) that considers aging and long-term weather conditions. This study proposed a robust design optimization method that deals with the selection of RES to achieve NZEB. Different case studies were evaluated: 1. Deterministic approach; 2. Markov chain-based reliability without the aging effect; 3. Markov chain-based reliability with the aging effect. The results showed that the optimal sizes of RES, considering the aging effect, were much larger than the other two cases based on the annual energy balance. Moreover, the consideration of the aging effect on the reliability assessment of the generation system for NZEB opens a pathway for a more robust and economic design of RES.</jats:p>

Performance Evaluation of a Direct Absorption Collector for Solar Thermal Energy Conversion

“…Owing to the increase of the population, the depleting trend of non-renewable energy resources must be taken into consideration [3]. Efficient energy use is a difficult task [4]. The existing literature describes different type of collectors that rely upon surface-based solar absorption and heat transfer, which is engaged by collectors to a…”
