The invention provides an alternating current/direct current hybrid microgrid optimized operation method considering micro-source surplus Internet access. The method comprises the steps that an alternating current/direct current hybrid microgrid optimized operation mathematical model including wind power generation, photovoltaic power generation, a battery, a diesel generator and a fuel cell is established; the alternating current/direct current hybrid microgrid mathematical model comprises a multi-objective, multi-constraint and non-linear objective function constructed with consideration ofpower grid purchase cost, micro-source fuel cost, environmental benefit cost, network loss, operation and maintenance cost, and micro-source surplus Internet access income, and the mathematical modelobeys the constraints of internal microgrid power balance, controllable micro-source climbing rate, upper and lower limits of battery charge and discharge per unit time, upper and lower limits of battery charge state, battery power balance before and after a time period, and unchanged battery charge state; a basic queue competition algorithm is improved to acquire an improved queue competition algorithm; and the improved queue competition algorithm is used to solve the alternating current/direct current hybrid microgrid optimized operation mathematical model. According to the invention, the microgrid operation cost can be effectively reduced, and the new energy consumption rate is promoted.
