Optimization of Load Dependent Start Tables in Marine Power Management Systems with Blackout Prevention

The paper describes optimization of operational procedures embedded in the power management system with regards to an overall vessel’ s safety and minimization of fuel consumption. Proposed method serves as an aid in a design of power management system but also reflects issues important in the marine power system design. The cost function and constraints have been formulated based on fuel consumption, operational profile of the vessel and blackout prevention in order to select load dependent start tables. The problem is formulated for the influence of generating sets inertia on overall blackout risk when using fast load reduction technology. The same formulation can also be used in the application of flywheel energy storage device technology onboard vessel. The proposed method can be applied to any vessel that requires more generating sets installed and special consideration of related safety issues in operations. With a properly addressed risk, the vessel can operate with closed bus-tie and have a maximum flexibility in operations in order to achieve the maximum fuel savings.
