DC shipboard microgrids are currently of interest since several benefits can be obtained from their adoption. One of the most important challenges in this type of systems is related to sudden load events that demand significant amounts of power within a short period of time. This kind of events leads to large deviations in voltage magnitude at the main dc busbars. To cope with this problem the usage of storage systems has been identified as a possible solution. This paper proposes a control strategy, based on the participation of a battery energy storage system, that aims to reduce the voltage deviations. In order to carry out the proposed strategy, only few signals are exchanged among the converters, while the required measurements are usually available locally at the installed devices. The proposed strategy can be adapted to the usual schemes used for on-board microgrids in order to effectively mitigates the voltage deviations under sudden load changes, with the aim to ensure secure operations and to increase the stability of the system.

Abstract
DC shipboard microgrids are currently of interest since several benefits can be obtained from their adoption. One of the most important challenges in this type of systems is related to sudden load events that demand significant amounts of power within a short period of time. This kind of events leads to large deviations in voltage magnitude at the main dc busbars. To cope with this problem the usage of storage systems has been identified as a possible solution. This paper proposes a control strategy, based on the participation of a battery energy storage system, that aims to reduce the voltage deviations. In order to carry out the proposed strategy, only few signals are exchanged among the converters, while the required measurements are usually available locally at the installed devices. The proposed strategy can be adapted to the usual schemes used for on-board microgrids in order to effectively mitigates the voltage deviations under sudden load changes, with the aim to ensure secure operations and to increase the stability of the system.File | Dimensione | Formato | |
