DESCRIPTION:Pulkit Nahata\nAbstract\nSolar PV based generation is a common
 ly observed form of distributed generation in low voltage networks. Resid
 ential PV systems depending upon their capacity partly feed the local load
 s. This reduces the stress on the distribution networks and improves the s
 ystem performance by reducing feeder losses. However\, a high penetration
  of PV resources results in local voltage rise during net power generation
 . This leads to an overvoltage and damages the connected loads. We propose
  a decentralized integral controller to curtail excess active power in ord
 er to avoid overvoltage. We prove the stability of the resulting closed-l
 oop system and guarantee that voltages of the generating nodes are within 
 the bounds specied by the grid standards. Considering the voltage and acti
 ve power constraints\, we show that the proposed controller leads to maxi
 mum power transfer into the grid. We discuss the objective of fair power c
 urtailment and show that it is in contrast with our objective of maximum p
 ower transfer. We also show that a voltage control is not be required for
  a few PV generators satisfying certain conditions. Finally\, the performa
 nce of the controller is presented through simulation studies.\n\nBrief Bi
 o\nPulkit Nahata graduated with a MSc in Electrical Engineering from ETH Z
 ürich in 2016. He specialized in systems and control with applications to
  power and energy systems. He jointly conducted his master’s thesis with
  the Automatic Control Lab\, ETH Zürich and ABB Corporate Research\, Bad
 en\, where he investigated the problem of overvoltage in microgrids with h
 igh PV penetration. \nHe conducted his Bachelor’s thesis on motion cont
 rol of underwater vehicles at IIT Bombay\, and has previously held positio
 ns with IISc Bangalore\, Vestas Wind Systems\, and ONGC India. His researc
 h interests are surrounded around distributed control of networked and c
 omplex systems with applications to energy and dynamic systems\, distribut
 ed sensor networks\, and underwater vehicles.
