In view of the problem of microgrid voltage exceeding allowable range caused by intermittency and instability of such renewable power generation（RPG）as photovoltaic and wind power etc

a kind of voltage regulation method of source load interaction combined with virtual synchronous generator（VSG）and electric spring（ES）is proposed in this paper. Firstly

the excitation controller of VSG is used to provide voltage support for the microgrid so to keep the voltage deviation of the power supply side within the allowable range. Secondly

the phase control of ES is used to keep the voltage deviation of the load node away from the power supply side and within a limit. Finally

the simulation model of the microgrid with VSG

renewable energy and ES is set up for simulation. It is shown by the simulation result that the voltage regulation of the power supply side can be realized by VSG and voltage regulation of the load side can be realized by ES

both of them form the voltage regulation mechanism of the source load interaction to maintain the voltage stability of the microgrid.
