STEADY-STATE MODEL OF LARGE-SCALE GRID-CONNECTED PHOTOVOLTAIC POWER GENERATION SYSTEM

摘要：

The characteristics of grid-connected photovoltaic (PV) power generation system are subject to environmental factors, grid voltage, and control strategies, so it is much difficult to model the system. In this paper, a steady-state model of PV generation system based on the power electronic converter is proposed. The model is divided into DC part, inverter and AC part, which can completely describe the steady-state operation of the system. If the model integrates with control strategies, the effect of strategies on system performance can be analyzed. The analysis of model example shows that the model can exactly describe the system, and accurately track the changes of operating point when irradiance or grid voltage changes.
