Research on the System Modeling and Control of Single-Phase Pv Flexible Grid-Connected

Abstract:

Photovoltaic systems can not meet the needs in the power grid without the impact, due to its penriodicity, intermittent and randomness, thus the key to solve the core technology of photovoltaic power generation system is important to achieve PV grid-connected. This article explains the two-stage topology system control and modeling of single-phase PV grid-connected: Modeling of DC / DC converter provides basis for maximum power point tracking; DC / AC inverter in grid-connected modeling offer efficient communication basis for grid-connected, it research on the control strategies for DC / DC and DC / AC circuit: that PV grid-connected complete alternating current of unit power factor using the booster circuit and inverter control structure, in order to offer photovoltaic systems flexible grid-connected the foundation.
