New Technique Trends for Power Converters in Distributed Power Generation Systems: Part II

OWER CONVERTERS have been widely adopted for distributed power generation systems, where the resonances may be excited. Although many innovative methods have been put forwarded to attenuate the appeared resonances and enhance the stability of system, how to keep high performance of power converters is still a big challenge for researches and engineers, especially when the power grid is weak and full of high order background harmonics. Fortunately, owing to the rapid progress in hardwares, such as improved power devices, more and more powerful local control processors, and advanced communication techniques, many interesting topologies, control methods, and online detection techniques of power converters emerge. All these techniques will inevitably affact the deveolpment of next-generation power converters in Distributed Power Generation Systems.
