Abstract

This paper makes a detailed analysis of the modeling method for photovoltaic (PV) arrays, maximum power point tracking (MPPT) controller and the power controller in Singlestage grid-connected PV system (SSGCPS). The detailed model of PV arrays is established, the MPPT controller and the power controller are designed under PSCAD/EMTDC environment. At last, the electromagnetic transient model of a 100kW SSGCPS is completed. The simulation results show that the simulation models can reflect characteristics and functions of the actual physical device accurately and can be used to the design and research of big-power PV system.
