The invention belongs to the technical field of power electronics, and particularly relates to an optical storage and charging control system and method. Comprising a grid-connected point E and a main control module, and the grid-connected point E is connected with a node D through a first air circuit breaker QF1; the node D is connected with the node B through a third alternating current contactor KM3; the node B is connected with the energy storage converter; the energy storage converter is connected with the photovoltaic energy storage module; the grid-connected point E is connected with the node C through a second air circuit breaker QF2 and a first alternating current contactor KM1 which are sequentially connected in series; the node C is connected with the node B through a second alternating current contactor KM2; the node C is connected with a load through a third air circuit breaker QF3; the first alternating current contactor KM1 and the second alternating current contactor KM2 are interlocked, and the second alternating current contactor KM2 and the third alternating current contactor KM3 are interlocked; and the main control module is used for acquiring the forward active power data of the grid-connected point E and controlling the output power of the energy storage converter according to the forward active power data. Through the interlocking relation between the alternating current contactors, power supply short circuit caused by sudden power supply of a power grid is avoided.
