Operation and Control of a Microgrid Containing PV Cells and Battery

Abstract:

Microgrids are LV or MV electric networks which utilize various distributed generators (DG)to serve local loads. They could operate in either grid-connected or island mode, and hence increase the reliability of energy supplies. In this paper, dynamic models of photovoltaic cell were described in ElectroMagnetic Transient Program/Alternative Transients Program(EMTP/ATP).In addition, basic models of the equivalent power electronic interfaces and batteries were developed.The above models have been integrated in a microgrid to represent the dynamic characteristic of steady state and transient operation. When operated under steady state, the PV cells could be able to deliver power supply to the load via electronic interfaces. When fault,the battery with P/V and Q/f control strategy based on the droop characteristics was developed to isolate the microgrid from the main grid in a rapid and seamless way,which contributing effective control of voltage and enhancement of system stability. Simulation results verify the feasibility of the proposed models.
