To meet with the ever-enhancing load demands, new transmission lines should be bolted-on in the existing power system but the economic and environmental concerns are major constraints to this addition. Hence utilities have to rely on the existent power system infrastructure with some modifications. To enhance controllability and boost power transfer potential of the existing power system the us...

In present day's energy conveyance frameworks is experiencing serious force quality issues. These force quality issues incorporate high responsive force trouble, music momentums, burden unbalance, unreasonable unbiased current and so forth. A few solutions for these force quality issues are accounted for in the writing. A gathering of controllers together called Custom Power Devices (CPD), whic...

This paper deals with sliding mode control of converter and its application to distributed generation. Sliding mode control is used to control the voltage source converter in voltage or current control mode. Modeling and control of H bridge converter system using sliding mode control is proposed. Easily implemented sliding surfaces provide prominent dynamic characteristics against changes in th...

Now-a-days for effective load compensation, a conventional three-level neutral point clamped (CNPC) inverter topology is more preferably used. This compensator, however, faces the problems of additional clamping diodes, which reduces the redundant switching states and improves the problem of capacitor voltage imbalance; further increasing the inverter cost. In this paper, a detailed analysis of...

Power electronic device, nonlinear and unbalanced loads have given rise to power quality problem in distribution systems. Due to factors like competitive generation patterns in a deregulated electric grid and an increasing level of sensitive end user devices, it has become necessary to ensure both reliable and power quality to the end customer. One way to betterment the power quality is using a...

Abstract: Voltage sag is considered to be the most serious problem of power quality. It is caused by faults in the power system or by the starting of large induction motors. Voltage sag causes about 80% of the power quality problems in power systems. One of the main reasons for voltage sag is short circuit fault, which can be compensated for by a distribution static compensator (DSTATCOM) as an...

With the growing penetration of distributed energy resources (DER), accompanying challenges have led utilities to limit hosting capacities DER installations on distribution feeders. A static synchronous compensator (DSTATCOM) is a power electronic device provide dynamic injections and absorption reactive into grid with more flexible reliable voltage control quality improvement. management syste...
