| Aimming at the essential nonlinearity of unidirectional Boost converter and bidirectional Buck-Boost converter.
DC/DC converters in Stand-alone Photovoltaic System, DC/DC converters were controlled by nonlinear control method of
passivity-based control. and combined with PI control of hybrid control. In order to incorporate two-stage battery
charging method. current-limitted charging and constant voltage charging, with effective control for DC bus voltage, two
control modes were employed for above DC/DC converters and for Boost converter and Buck converter, and passivity-
based control for current regulation and passivity-based control for voltage regulation were designed . Finally, the
simulation results show that the effectiveness of control method is proposed for stand-alone photovoltaic system energy
management. |
