Abstract： To solve the problems of high energy cost and high carbon emission in ports，an open-loop and closed-loop hybrid control strategy involving hydrogen-electricity energy flow is proposed based on the integrated energy system of“source-grid-load-storage”. With the goal of optimal economy，in view of the energy-load imbalance of the port，flexible interconnection equipments and hydrogen-electricity energy storage systems are introduced to realize the energy balance scheduling at spatial and temporal scales，and the utilization rate of clean energy in ports is improved through hydrogen-electricity energy flow conversion. Considering the constraints of electric energy storage，flexible interconnection，power grid flow，hydrogen energy equipment，etc.，an open-loop and closed-loop hybrid control model of energy flow in integrated energy systems is constructed. The second-order cone relaxation method is used to convert the nonlinear constraints of power grid flow，and the control model is solved using the commercial solver CPLEX. Taking a port area of Ningbo Zhoushan Port as the research object，the scenario clustering of the energy potential in the port area is implemented using K -means ++ algorithm，and the proposed energy flow open-loop and closed-loop hybrid control strategy is verified in typical source-load scenarios. The results show that the proposed control strategy can reduce the operating cost by 12.04% ，reduce CO （204号 2 emissions by 5.15% ，and improve the utilization rate of clean energy by 14.28% on average in four typical scenarios.
