Research in the area of power system, incorporating optimal power flow and optimal load shedding, has been used in classical dispatch problems to determine control adjustments to remove line overloads. This paper reports a rule-based load shedding in a ship power system. To filter critical outages and congestion cases, a load shedding rule-based system is implemented. The algorithm searches for...

Multi-Agent System for Predictive Reconfiguration of Shipboard Power Systems. (December 2003) Sanjeev Kumar Srivastava, B.E., University of Gorakhpur; M. Tech., Indian Institute of Technology, Delhi Chair of Advisory Committee: Dr. Karen Butler-Purry The electric power systems in U.S. Navy ships supply energy to sophisticated systems for weapons, communications, navigation and operation. The re...

Ships play the major role in bulk transportation and they need their special energy system. This paper proposes a stochastic programing method for optimal sizing of a hybrid ship power system with energy storage system (ESS), photovoltaic power (PV) and diesel generator. To account for uncertainties, in this study a two-stage stochastic mixed-integer non-linear programing is used to model the o...

Fine alignment of main ship power plants mechanisms and shaft lines provides long-term and failure-free performance of propulsion system while fast and high-quality installation of mechanisms and shaft lines decreases common labor intensity. For checking shaft line allowed stress and setting its alignment it is required to perform calculations considering various stages of life cycle. In 2012 J...

Hilbert-Huang Transform (HHT) and its improved method are introduced to detect and analyze power quality in ship power system for the first time, in this paper. The HHT method is used to detect surge current, voltage sag and swell, voltage interruption, etc. of the ship power system. By means of Hilbert-Huang transform, Beginning time, ending time, time-frequency, timeamplitude of the disturban...

Ship microgrids have recently received increased attention, mainly due to the extensive use of power electronically interfaced loads and sources. Characteristics of these microgrids are similar to islanded terrestrial microgrids, except the presence of highly dynamic large loads, such as propulsion loads. The presence of such loads and sources with power-electronic converter interfaces lead to ...
