Abstract:The topology of integrated energy system of wind, photovoltaic and hydrogen is established. With the goal of grid-connected power tracking the demand of power grid, taking the minimum technical output and rated power of the electrolyzer, rated power of fuel cell and pressure of hydrogen storage tank as constraints, an online energy control strategy of a wind-photovoltaic- hydrogen integrated energy system is proposed. An integrated system experimental platform is established and an online monitoring system of integrated system is developed, using the simulator of 3kW direct drive permanent magnet synchronous wind turbine, simulator of 5kW grid connected photovoltaic array, 1Nm3/h alkaline hydrogen generation by electrolysis of water, 2.5kW proton exchange membrane fuel cell, and 2×5Nm3 hydrogen storage tank. Effectiveness and stability of the proposed online energy control strategy and the developed online monitoring system are verified by experiments, based on the established physical experimental platform.
