High Energy Efficiency Operation and Control of DC Shipboard Grid with Active Front End Networking
摘要
Abstract
The DC shipboard grid provides an effective and feasible solution for the eco-friendly transformation of the shipping industry.Considering operational of real ships,a hierarchical coordinated control strategy is proposed,which mainly includes a bottom control system for the coordinated operation of power units in the DC shipboard grid with an ac-tive front end networking and a power management system.The bottom control system is mainly used to realize the non-static error following of the generator set's speed and dynamic/steady-state power sharing among diesel generator sets with different capacities.The power management system is mainly responsible for improving the bus voltage quality and system energy efficiency.Finally,the efficacy of the control strategy is verified by results of simulations and a hardware-in-the-loop simulation system,showing that this strategy can effectively improve the energy efficiency of system opera-tion and save up to 10%of fuel.关键词
