Dynamic Simulation Based Analysis of a New Load Shedding Scheme for a Notional Destroyer Class Shipboard Power System

In this article, an expert system based load shedding scheme for ship power systems is revisited. In this load shedding scheme, a popular decision making tool termed the analytical hierarchy process, is utilized for prioritizing the loads to be shed onboard a notional all-electric ship power system. The analytical hierarchy process based load shedding scheme overcomes some of the major drawbacks of traditional load shedding schemes implemented on ship power systems by minimizing the number of loads disconnected, differentiating the priority of loads based on system conditions, and considering a wider ranger of factors that may potentially influence the shedding of electrical loads. An illustration of the developed load shedding scheme implementation to a destroyer class shipboard power system simulated in a real time digital simulator is presented.
