The invention discloses a micro-grid subnet structure and control method with constant and time-sharing output impedance. The subnet structure comprises a continuous load, a non-continuous load, a storage battery, a bidirectional inverter of the storage battery, a photovoltaic cell, an inverter of the photovoltaic cell, a var generator, other energy, inverters of other energy, a subnet output impedance controller and an active filter. The resistive impedance output by subnets is controlled by controlling active components of charging and discharging currents of the storage battery, active components of output currents of the photovoltaic inverter and switching of the non-continuous load, the inductive impedance output by the subnets is controlled by controlling reactive components of all inverter output currents of the subnets and reactive currents of the var generator, and therefore the constant and time-sharing subnet output impedance is achieved so as to meet the dispatching requirement ...
