A well-known problem of three-level neutral point clamped (NPC) inverter is the voltage imbalance in the dc-link capacitors. This paper proposes the dc-link capacitor voltage balancing method where a common offset voltage is injected. The offset voltage consists of a harmonic voltage and a magnitude difference between the upper and the lower capacitors. Theoretical analysis is provided to balance...
The integration of Distributed Energy Resources (DERs) into the future Smart Distribution Network (SDN) has challenging issues regarding the successful development of smart grids. The SDN offers new opportunities in the improvement of the efficiency of power distribution networks. The DERs will be distributed in the existing distribution networks, interconnected in customer areas and operated on its...
IT appliances such as TV, computer and monitor are used in many households, but they consume energy even when they are not in use to maintain a convenient ready state for instant on-demand use. It is called ‘standby power’ or ‘vampire power’. Most of the standby power used by appliances is not performing any useful function. It is a small amount of electricity for households, but it is a great loss...
