The invention discloses a photovoltaic-battery microgrid energy dispatching management method based on a dynamic wholesale market value. The method comprises: step one, designing a photovoltaic current equivalent circuit model of a photovoltaic power generation system; step two, establishing a maximum power output rate model of the photovoltaic power generation system; step three, establishing anequation relationship between a voltage and a current of a battery; step four, establishing a relationship between the number of times of charging and discharging of a lithium-ion battery and the depth of charging and discharging; step five, establishing a total economic benefit model of a photovoltaic-battery microgrid system; step six, establishing a highest net preset value (NPV) and SSR modelof the photovoltaic-battery microgrid system; and step seven, controlling switching of a storage battery unit formed by lithium batteries in the photovoltaic-battery microgrid system among different operating states. According to the invention, with the photovoltaic-battery microgrid energy dispatching management method, the economic benefit of the microgrid system is increased while the high reliability and self-sufficiency rate of the microgrid system are considered and guaranteed.
