Control strategy of microgrid based on distributed generation
Upon the traditional wind-solar hybrid distributed generation system,a single-phase microgrid experimental system platform has been built based on the DC bus,Z topology was used to increase the energy utilization ratio.On the basic of realizing the maximum power point tracker of the new energy,different microgrid controlling strategy has been designed to apply to the island and grid connected operation mode:in the cases of island running,master slave control mode will be utilized in the system and the battery will be used as the main control unit to provide the reference voltage; on the other hand,a control method which can merge the generation into the grid as much as possible will be adopted in the case of grid connected.By the use of system model,the simulation of the two operation mode switch state and power flow has been done and the feasibility and effectiveness of the control strategy can be guaranteed,it also has been verified by the microgrid experimental platform.
