This paper deals with the elimination of harmonics at PCC in the presence of non-linear type of loads. Introduction of five-level DSTATCOM at PCC injects compensating currents for the minimization of harmonic content in the source currents. Non-linear loads when connected to the system draw non-linear components of current leaving undesired harmonics at the source side. DSTATCOM when connected ...

In order to deal with power quality problems under distortional and unbalanced load conditions, this paper presents a new control method for a four-wire three-phase unified power quality conditioner (UPQC) which is based on instantaneous power p-q theory. The proposed control approach is based on instantaneous power and is optimized by using a self-tuning filter (STF), without using any low-pas...

Load currents through the power and distribution transformer and line impedances cause voltage drops, which reduce voltage magnitude at the loads. Voltage magnitudes at service locations must be maintained within specified ranges. This is accomplished in both fixed designs of the system (e.g., conductor selection, substation and distribution transformer tap settings, fixed capacitor banks) and ...

This paper proposes a new analytical method for transmission power loss allocation for pool-based markets in restructured power systems. It is based on circuit laws and the concept of orthogonal projection. In this method, the current flow in each branch is divided into two components by using the superposition principle. The first one is due to the power transfer from generators to distributio...

High power LED converter combined with switching power supply and current adjustment device for is presented. The switching power supply provides one stabilized voltage source, and the current adjustment device controls the output currents with a desired constant current and the over-load protection. The experiment results shows the circuit can work well and pass the load test and the electroma...

This article presents a low quiescent current output-capacitorless quasi-digital complementary metal-oxidesemiconductor (CMOS) low-dropout (LDO) voltage regulator with controlled pass transistors according to load demands. The pass transistor of the LDO is segmented into two smaller sizes based on a proposed segmentation criterion, which considers the maximum output voltage transient variations...

In this paper we present a new methodology for the formulation of efficient load signatures towards the implementation of a near-real time Non-Intrusive Load Monitoring (NILM) approach. The purpose of this work relies on defining representative current values regarding the 1st, 3rd and 5th harmonic orders to be utilized in the load signatures formulation. A measurement setup has been developed ...

Modern automobiles incorporate more actuators, heaters, and other electrical loads than have automobiles in the past. This proliferation of high current, high power loads is presently challenging the longstanding assumption that the entire chassis will remain at one potential under a variety of different operating conditions. New voltage standards, alternator designs, and power electronics ensu...
