With the growth in customers’ demand diversification, mixed-model U-lines (MMUL) have acquired increasing importance in the area of assembly systems. There are generally two different approaches in the literature for balancing such systems. Some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...

Three-phase three-level dual-active-bridge (3L-DAB3) converters are a potential topology for high-voltage and high-power applications. Neutral-point voltage balancing is complex important issue (3L) circuits. Compared with the single-phase 3L converter, self-balancing capability of 3L-DAB3 limited. To guarantee reliability neutral-point method proposed in this paper. First, principle analyzed. ...

Integration of distributed generations (DGs) in power grids is expected to play an essential role in the infrastructure and market of electrical power systems. Microgrids are small energy systems, capable of balancing captive supply and requesting resources to retain stable service within a specific boundary. Microgrids can operate in grid-connected or islanding modes. Effective islanding detec...

Correlate is a concurrent object-oriented language, which supports active objects as a unit of concurrency. In this paper, we discuss the migration of active objects in Correlate. First, we will show that the architecture of the run-time system simplifies the realisation of a migration mechanism that supports active objects, because this particular run-time system has complete control over all ...
