DESCRIPTION:István Táczi shared experiences about a detailed case study c
 onducted by E.ON Hungary\, the largest distribution system operator in the
  country and the Budapest University of Technology and Economics. The goal
  was to mitiage the voltage rise caused by the local PVs on a low voltage 
 network (with high R/X ratio). To solve the issue cost-effectively\, a pro
 totype inline voltage regulator (IVR) was developed in the cooperation (Fi
 gure 1.). The primary objective function is to control the effective value
  of the voltage (decrease when distributed generation is high\, increase w
 hen local load is high)\, the secondary functions include further – cust
 omizable – power quality improvement possibilities. This enhances the ac
 tivity of distribution system operators with a flexible smart grid element
  to meet the customer needs and regulatory restrictions. The main advantag
 es compared to the current state of the art technologies are:\n\n- continu
 ous (no taps\, switching transients due to the inverters) control function
 \n- proper filtering (low level of harmonics\, quality improvement\, neutr
 al point coupled inverters with high switching frequency)\n- possible asym
 metry compensation\n- ~1 ms control time delay (fast operation)\n- integra
 ted electrical protection\n- quick commissioning and installation\, no sup
 ply interruption is needed in case of a failure\n- remote control\, measur
 ement and automatic error handling capability\n\nThe prototype successfull
 y reduced the voltage fluctuations. Due to it’s competitive price – co
 mpared to installing new transformer stations – this solution will be ro
 lled out in many cases to effectively integrate the growing number of PVs 
 in Hungary.\n\nThe students gathered information about current research an
 d innovation activity which was done by a local company and a local univer
 sity. Also these events are important to keep in touch with the young gene
 ration and facilitate their technical development and contacts with IEEE.\
