Abstract :
Dual-power PV-grid system was introduced to manipulate the lower tariff rate at off-peak period and to reduce the capital installation cost of PV energy system. In this paper, the system configuration, architecture and operation of the dual-power PV energy system are described and discussed. From the review of various multilevel inverter topologies and switching control strategies, the cascaded H-bridge utilizing sinusoidal pulse width modulation (SPWM) or closed loop current control has been identified as the most appropriate inverter topology and control scheme for the system.
