Descripción:
The modeling and simulation of photovoltaic power generation system has become an important issue in the field of power generation. Research on the characteristics of photovoltaic (PV) grid-connected system by hardware-in-the-loop simulation could provide convenient experiment condition and accurate result. This article designs a photovoltaic grid-connected simulation platform for digital/physical hybrid real-time simulation, in which RTDS uses a digital-to-analog interface to communicate with external DSP devices. Maximum power point tracking (MPPT) and grid-connected control of a 520kWp PV system are performed on the platform. And the feasibility and effectiveness of hybrid PV system are validated by the analysis of hardware-in-the-loop result in RTDS.
