Abstract:
The accurate modeling of micro-grid access to power system planning and design stage needs is the primary problem to solve. This paper modeled the micro grid photovoltaic power generation system, including silicon solar cell, photovoltaic inverters, battery energy storage system, and the micro power distribution system. In the use of power system analysis software (DIGSILENT) of actual power system simulation, the simulation results verify the model's correctness. In the power grid fault disturbance, the light intensity of disturbance and the load disturbances, the simulation results show that the optical storage combined with micro network has fast dynamic response characteristics, and its network of gridconnected voltage influenced by the changes of the light and load is little, while more affected by the network fault influence.
