Electric spring (ES) is a new technology inspired by the idea of realization system that equivalent to mechanical springs in terms functionality within power systems. are comprised from DC voltage source, an inverter and LC filter at grid side. It can be used effectively systems perform many functions such as regulation, reactive compensation, demand management energy storage. On other hand, du...

To increase the power rating and reduce cost complexity of a multi-pulse rectifier (MPR), it is well known that pulse number must be increased. In some practical cases, 12-pulse (12PR) suggested as good solution considering its relatively simple structure low weight. However, rectifiers cannot technically meet standards harmonic distortion requirements for industrial applications, therefore the...

In this paper, a simplified control algorithm based on unit vector template generation (UVTG) is proposed for a stardelta supported three-phase four-wire (3P-4W) unified power quality conditioner (UPQC) topology for the improvement of different power quality problems. Different topologies reported in literature for 3P-4W UPQC use active compensation for the mitigation of source neutral current ...

The microgrid concept has been emerged into the power system to provide reliable, renewable, and cheaper electricity for rising global demand. When microgrids are introduced, there will be several concerns, such as active reactive powers' sharing, load management, connecting main grid, voltage current deviations. Recently, with fast deployment of distributed generation, methods mitigate harmoni...

Current conservation mitigation plans often fail to ensure full in-kind habitat replacement for endangered species, which suggests the need for improved methods for calculating mitigation credits. A simple, yet biologically meaningful method for calculating mitigation credits would be to let the number of mitigation credits assigned to a parcel of land scale with the reproductive value of the i...
