Shipboard Integrated Power System (IPS) and electromagnetic weapons are two symbolic technologies of future advanced ships. Medium-voltage DC (MVDC) IPS indicates the trend of shipboard IPS. In IPS, the application of electromagnetic weapons is equivalent to the integration of high-power pulse loads (HPPL). The integration of HPPL in IPS may cause problems in mathematical modeling of special devices, network topology design and coordinated control. Aiming at such problems, the project will firstly unravel the dynamic characteristics of HPPL energy storage (ES) devices through mathematical modeling of typical HPPL. The research results will show that charging process of ES devices is long and continuous, with a relatively lower charging power, while the discharging process is often short and repetitive, with a high pulse power. Secondly, by proposing the concept of “Flexible Energy Storage Supply Network (FESSN)”, the project will research the optimal topological design of FESSN and MVDC IPS with FESSN integration. A new IPS topology will be designed, in which the FESSN will supply power to HPPL with centralized ES and it’s also integrated in the IPS in a distributed fashion. Thirdly, by researching the adaptive variable topological control of FESSN and the parallel control of conventional power sources and ES, the coordinated control system of MVDC IPS with HPPL integration will be built. The research results will lay theoretical foundation for the flexible integration of multiple types of HPPL and their safe, efficient and compatible operation within MVDC IPS.
