“…It discharges 1000 A in 300 millisecond with a ramp-rate current of 3.3 kA/s. Because the discharge rate is controlled by both Vref and Ismes, the discharge rate is decreased when SMES current decreased by (9). The goal of decreasing the discharge rate of SMES is to slow down the voltage drop in the main DC bus, thus giving more time for the battery to responds.…”

“…There are three operation modes: the charge mode, the discharge mode and the standby mode. The charge/discharge rate of the SMES is not only controlled by Vref, but also controlled by the amount of the current stored in the SMES by (8) and (9). The goal of this control method is to change the charge and discharge rates of SMES based on the amount of the current stored in SMES to avoid the sharp charging and discharging.…”

“…The goal of this control method is to change the charge and discharge rates of SMES based on the amount of the current stored in SMES to avoid the sharp charging and discharging. When SMES current decreases the discharge rate of the SMES decreases by (9), the voltage drop in the main DC bus slow down, thus the battery bank has more time to discharge to maintain the main DC bus at the required level. The three operation modes are shown in Fig.2.…”

Abstract-As the capacity of all-electric ships (AES) increases dramatically, the sudden changes in the system load may lead to serious problems, such as voltage fluctuations of the ship power grid, increased fuel consumption and environmental emissions. In order to reduce the effects of system load fluctuations on system efficiency, and to maintain the bus voltage, we propose a hybrid energy storage system (HESS) for use in AESs. The HESS consists of two elements: a battery for high energy density storage and a superconducting magnetic energy storage (SMES) for high power density storage. A dynamic droop control is used to control charge/discharge prioritisation. Manoeuvring and pulse loads are the main sources of the sudden changes in AESs. There are several types of pulse loads, including electric weapons. These types of loads need large amounts of energy and high electrical power, which makes the HESS a promising power source. Using Simulink/Matlab, we built a model of the AES power grid integrated with a SMES/battery to show its effectiveness in improving the quality of the power grid.  Index Terms--All-electric ship (AES), hybrid energy storage system (HESS), superconducting magnetic energy storage (SMES), pulse load.
