The demand of reactive power in the last mile of the networks is increasing by the time due to the change of loading types by time, beside increasing the total demand itself where new technologies are being introduced depend mainly on different types of electrical support such as electrical cars and more electronic devices in consumption process [1]. This expected situation would lead to take into...
Visions of future power systems contain high penetrations of inverters which are used to convert power from dc (direct current) to ac (alternating current) or vice versa. The behavior of these devices is dependent upon the choice and implementation of the control algorithms. In particular, there is a tradeoff between dc bus ripple and ac power quality. This study examines the tradeoffs. Four control...
In this paper, a new control strategy based on current mode control for dynamic voltage restorer (DVR) is proposed to mitigate the power quality problems in the supply voltage. The DVR is controlled indirectly by controlling the supply current. The reference supply currents are estimated using the sensed load terminal voltages and the dc bus voltage of DVR. The control scheme is based on synchronous...
Nowadays, several manufacturers offer intelligent electronic devices (IED) or intelligent controllers to improve network performance. On the other hand, several reports are produced to define how the intelligent distribution system should look. Hydro-Quebec already proposed that the intelligent distribution network should include: network monitoring equipment monitoring, product monitoring In order...
