Optimal Design and Power Management in Shipboard System

Abstract

This paper deals with controlling DC power in shipboard power. Shipboard Power System (SPS) experiences disturbance due to variations in load. A DC bus distribution system developed for the U.S. Coast Guard's 270-ft Medium Endurance Cutter is simulated using MATLAB in this paper. Whenever a fault occurs in load, the system power varies. In this paper, the DC power system is controlled automatically by detecting disturbances. The proposed method includes selfgoverning fault detection and controlling DC power. The shipboard power system consists of a challenge related to restoration. The reliability and flexibility of the system are improved with effective integrated Energy Storage Devices (ESD) and Solar power. A maiden attempt is made in the paper with a solar panel for the cost-effective operation of the SPS. Also, the SPS with and without the solar panel is tested for optimal operation. Furthermore, this shipboard management system may be implemented in the Indian shipboard system for optimal power management.Index Terms: Optimal power management, DC bus distribution system, shipboard power system, energy storage system, solar power, fault detection, energy storage device.

A Comprehensive Review of Modeling and Optimization Methods for Ship Energy Systems

“…In [71] the implemented fuzzy-based PSO algorithm provided faster convergence to the optimal point than the traditional PSO and Dynamic Programming methods. Mummadi and Vijay [72] presented an optimal control study, under load changes and faulty conditions, for a DC power system of a vessel. Automatic, self-governing, real-time control was achieved, maintaining the power balance and systems' reliability, even after the faults' detections and isolations.…”
