Quantifying energy not served in power capacity expansion planning with intermittent sustainable technologies

  • Andreas Poullikkas American University of Sharjah, UAE


In this work, estimations are made of the energy not served (ENS) in a power capacity expansion problem in the case ofintegration of intermittent sustainable technologies. For this purpose, part of the power generation system of the UnitedArab Emirates (UAE) is examined. Five capacity expansion scenarios using sustainable power generation technologiesare investigated, including the integration of carbon capture and storage (CCS) technologies and solar-based powergeneration systems (intermittent systems as well as dispatchable systems using thermal storage), and compared withthe business as usual scenario (BAU) for various natural gas prices. Based on the input data and assumptions made,the results indicate that the BAU scenario is the least cost option. However, if the UAE move towards the use ofsustainable power generation technologies in order to reduce carbon dioxide emissions, the most suitable alternativetechnologies are: (i) natural gas combined cycle technology integrated with CCS systems, and (ii) concentrated solarpower systems with 24/7 operation. The other candidate sustainable technologies have a considerable adverse impacton system reliability since their dispatchability is marginal, leading to power interruptions and thus high ENS cost.
