Programmed PWM to improve power quality in systems with distributed generation units
Pulse-Width Modulated (PWM) inverters are widely applied in Distributed Generation (DG) units and power quality equipment owing to their excellent performance and flexible control means. Programmed PWM (PPWM), as a special type of optimal PWM strategy, theoretically allows for setting the fundamental and the selected harmonic amplitudes directly to arbitrary values. The algorithms for solving ...

The electricity meter follows the new development trend of the EV charging station
Currently, pure electric vehicles can not completely replace gasoline vehicles. For users, the priority problem is battery sustainability. For premium and middle-end electric vehicles are able to 500km pure electric battery sustainability. Actually should take many factors into consideration, electric vehicles are able to 400km basically. This range is similar with traditional gasoline vehicles. ...

Cascade failures and distributed generation in power grids
Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...
