Abstract

The application discloses a ship power generation unit load cooperative control method and system based on real-time power, and particularly relates to the field of power regulation of a ship hybrid power system; and is used to solve the problem of control disorder of an energy storage system caused by the conflict between two types of instructions, i.e., maintaining the load of a power generation unit and suppressing power fluctuation of an electric network; the real-time evolution trend of transient power demand data is acquired and analyzed to predict high-risk working conditions; in the working conditions, the matching degree of the energy storage system and the power demand is evaluated in parallel, and the change rate of the internal structure of the power demand is analyzed; based on the above evaluation results, the recovery priorities of the two types of control instructions are dynamically decided, and the instruction with a higher priority is set as a dominant power instruction; the dominant instruction and the other instruction are coordinated and arbitrated based on real-time power margins to generate a final executable power instruction; and the accurate and orderly cooperative control of the power of the energy storage system is realized, and the overall operation stability of the ship power system under complex transient working conditions is improved.
