| Abstract |
This paper presents how to design the configuration of generation system for shipboard power system based on fuel cost analysis.
We propose a sophisticated economic analysis method with detailed fuel cost evaluation, which can be obtained from actual specific fuel consumption (SFC) characteristics of the gas-turbine and diesel generators installed in existing ships. Using the proposed method, we analyze economic benefits for optimal configurations of shipboard generation system for both hybrid propulsion ships such as CODLOG (COmbined Diesel-eLectric Or Gas-turbine) and COGLOG (COmbined Gas-turbine eLectric Or Gas-turbine) and full electric propulsion ships. In addition, we analyze the effects of energy storage system (ESS) in shipboard power systems in terms of spinning reserve management and single generator operation mode to meet the reliability and survivability requirement. The effectiveness of the proposed method is verified through multiple case studies with actual measurement data in ships that are currently in operation |
