A Study on Practical Generation Resource Mix Using the Enhanced Screening Curve Method

Abstract

Mitigation strategies for climate change will require the reduced use of fossil fuels to generate electricity and replacement of these fuels with renewable generating resources. The screening curve and load duration curve were used to determine the optimal generation resource mix with renewable generating resources. In this paper, practical generation mix simulation was performed by applying screening curve method (SCM) including start-up effect to the National Renewable Energy Laboratory-118 (NREL-118). The applied SCM reflects the short-term operational impact of renewable energy and maintains its simplicity while increasing the accuracy of the optimal generation resource mix solution. In future, the elaborated SCM can be developed by considering other operational constraints such as ramp rate, minimum stable level, and heat rate. © The Korean Institute of Electrical Engineers This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/4.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
