Reconfiguration of MVDC shipboard power systems: A model predictive control approach

Abstract

In this paper, a reconfiguration method based on Model Predictive Control (MPC) is proposed for a nonlinear Medium-Voltage DC Shipboard Power System. By applying the proposed MPC approach, the reconfiguration is formulated as an optimization problem with respect to operating constraints and also the priorities of loads. The loads are categorized as vital loads, semi-vital loads, and non-vital loads by the appropriate weighting factors. The main goal is to maximize the power delivered to the loads with respect to power balance and generation limits. The simulation results of three cases with the use of a nonlinear MVDC SPS model are given to illustrate the effectiveness of the proposed method.
