Operation Mode Switching Strategy of Series Hybrid Electric Ship Power Systems

To solve the problem of switching operation mode of hybrid energy systems of inland ships, a mode control strategy was proposed. Considering the remaining power battery charge, battery temperature, and ship propulsion power as feature factors, and operation modes of hybrid energy systems as decisive output, this paper established an operation mode switching system model and control strategy for hybrid power systems based on fuzzy comprehensive evaluation method, and implemented related simulations using data collected from hybrid ship laboratory. The result shows that the proposed mode control strategy can intelligently and automatically switch the operation mode, which can not only realize optimized management on hybrid energy systems of electric ships, but also ensure battery performance, and extend battery life.
