Decentralized grid-connected photovoltaic (PV) system with reactive power compensation has been gaining increasing attentions due to its outstanding performance. But with traditional control strategies, unbalanced voltages caused by loads will greatly affect the compensation performance and in severe case may even cause it shut down for overcurrent protection. This paper presents a novel fundamental...
With the development of renewable energy, distributed generations such as photovoltaic generation, wind power systems need to be connected to a utility power grid for the systems to work effectively as energy sources. Islanding detection is one of the most important techniques to develop for the distributed generation systems. A novel active islanding detection algorithm based in pseudo-random signal...
In a previous paper, the authors proposed an orthogonal-core type dc-ac converter for use in photovoltaic power systems. The dc-ac converter has such desirable features as a simple construction, high degree of safety, and, ease of maintenance. The operating characteristics of a single-phase converter for residential photovoltaic power systems have also been reported. In this paper, we discuss the...
