摘要
Abstract
The direct power control based on voltage oriented (V-DPC) was applied to a PV grid-connected inverter control strategy and the concept of estimation of the grid voltage and instantaneous power was introduced, taking the instantaneous active power and reactive power with the grid-connected inverter output as the controlled variables for power direct closed-loop control. The system need not to detect the transformer secondary voltage, the grid voltage sensor was omitted, and consequently the shortage of current control scheme was not only overcome, but also the cost was reduced. The system had the advantages of good robustness and simple control structure. The principle of voltage oriented-direct power control was analyzed, the specific parameters of the inverter were designed, and the simulation and experiment results were given.关键词
