Sažetak
This paper describes the optimization of marine power system design and power management system (PMS) unit commitment algorithm. The optimization is based on a probabilistic approach to vessel operational conditions with regards to blackout prevention and minimization of fuel consumption. The generator commitment problem has been solved using long term probability of sea states and expected values of wave heights based on weather statistics. The problem is analyzed by taking care of proper selection of vessel’ s operational profile, total installed power, number of generator sets, power rating of each unit, load dependent start/stop tables and load sharing among generators. The cost function is based on fuel consumption and operational requirements. Minimization of fuel consumption has been analyzed with respect to efficient use of fast load reduction technology where generating sets inertia has important influence on the power system speed of response and direct influence on risk of the blackout. Redundancy requirements with respect to blackout prevention are also included in the optimization. The proposed optimization scheme can be used in marine power plant design and application of any technology that influence power system inertia such as flywheel energy storage devices, batteries and fuel cells.
