Research of Grid-Connected Operation Control of PV Cells in Microgrid

Abstract:

A control model of PV cell operating in grid-connected state is researched in this paper. Based on the equivalent circuit of PV (Photovoltaics) cell and its mathematical model, a general engineering control model of photovoltaic array is established. The MPPT (Maximum Power Point Tracing) algorithm is realized by controlling the duty cycle of BOOST circuit to tracing the maximum power, and the control strategy of double closed-loop control of voltage and current guarantees stable DC output and rapid dynamic responses of current. The simulation model can provide guidelines for practice engineering design.
