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...

Introduction: Radiotherapy is one of the effective methods in the treatment of cancer. In the recent methods of radiotherapy, intensity modulated radiotherapy (IMRT) technique by compensators is used. when photon beam passes the compensator, scattered photons can be generated within the compensator. The presence of scattered photons may complicate the design of compensators as...

Recently the compensator has been shown to be an in expensive and reliable dose delivery device for photon beam intensity-modulated radiation therapy (IMRT). The goal of IMRT compensator design is to produce an optimized primary fluence profile at the patient's surface obtained from the optimization procedure. In this paper some of the problems associated with IMRT compensator design, specifica...

Abstract A novel control strategy of synchronous compensators and converters is proposed to increase the ability line commutated converter (LCC) based HVDC systems successfully recover from commutation failures (CFs). The dynamic var support one most important factors, which impact process. Many have been implemented enhance transient voltage stability for improving CF recovery performance. How...

The detection of potential voltage collapse in power systems is essential to maintain the stability heavy load demand. This paper proposes a method detect weak buses using two indices: margin factor (dS/dY) and prediction index (VCPI). Hence, aims improve Iraqi transmission grid by allocating FACTS devices optimal locations sizes. Two types are used this which Thyristor controlled series compen...

When a brass compensator is set in a treatment beam, beam hardening may take place. This variation of the energy spectrum may affect the accuracy of dose calculation by a treatment planning system and the results of dose measurement of brass compensator intensity modulated radiation therapy (IMRT). In addition, when X-rays pass the compensator, scattered photons are generated within the compens...
