The invention provides a light storage type electric vehicle charging station operation control system and method, and belongs to the technical field of new energy vehicle charging, and the system comprises a micro-grid operation control module, a DC bus, an energy storage module, a photovoltaic module, a charging station load and a large power grid. The photovoltaic module, the energy storage module and the charging station load are all hung on the direct-current bus, and a bidirectional converter is connected between the large power grid and the direct-current bus; the micro-grid operation control module collects the operation state of the photovoltaic module, tracks the maximum power point of the photovoltaic module, collects the operation state of the energy storage module, controls the charging and discharging operation state of the energy storage module, collects the operation state of the bidirectional converter, and controls the switching direction of the bidirectional converter. According to the invention, the utilization rate of photovoltaic power generation is improved through power tracking, and the stability of the DC bus voltage of the micro-grid and the full utilization of photovoltaic power generation are realized through the charge and discharge control of the energy storage module and the grid-connected control of the bidirectional AC controller.
