Abstract
Ship power grid end to have high power load, and ship start-stop, backward, steering and a series of actions will seriously affect the ship the dc bus voltage of power grid, which threaten the sailing safety. And based on the ship power grid structure design of hybrid energy storage system, which can be used to reduce the bus voltage fluctuation problem. Therefore, study the capacity of the hybrid energy storage system configuration and cost optimization has certain reference value and practical significance. This paper presents a hybrid energy storage system for the life of the wear model and the equivalent cost model, presents a hybrid energy storage capacity optimization constraints, to develop the capacity of the hybrid energy storage system configuration optimization process, The improved particle swarm optimization (pso) with chaos theory was used to optimize the total cost of the energy storage components according to the constraint conditions.
