摘要：
A virtual space vector pulse-width modulation (SVPWM) based power control scheme is investigated for the multi-port dc-ac converter in PV-battery hybrid systems. Two dc ports interfaced with PV and battery, and one ac port interfaced with ac grid, can be provided by the multi-port dc-ac converter, simultaneously. In order to realize flexible active power flow among PV, battery and ac grid, an outer power control loop with an inner virtual SVPWM scheme is analyzed in detail. The power regulation range of the multi-port dc-ac converter with the presented control is discussed. The feasibility and effectiveness of the control and modulation scheme is verified by experimental results.
