The unified power quality conditioner (UPQC) with shunt inverter and series inverter are usually employed for elimination of current and voltage related power quality issues. However, elimination of voltage and current quality issues in a grid connected Photovoltaic (PV) system is essential. Therefore, PV integrated UPQC topology is proposed in this paper with a novel controller for power quality improvement. The control algorithm based on notch filter Phase Locked Loop (PLL) is utilized for proper phase detection and elimination of voltage and current disturbances. PV tied UPQC controller based on notch filter PLL has the capability to avoid multiple zero crossing during highly distorted grid voltage condition. Conventional control algorithms such as synchronous reference frame theory, unit vector controller based on traditional PLL are also analyzed for the control of PV tied UPQC. The proposed system is developed in Matlab\/Simulink and the results obtained are evaluated to measure the performance. A real-time hardware prototype is developed using dSPACE processor. The obtained experimental results validate the efficiency of the proposed controller for PV tied UPQC.<\/jats:p>","DOI":"10.1177\/0142331218790314","type":"journal-article","created":{"date-parts":[[2018,8,13]],"date-time":"2018-08-13T10:24:27Z","timestamp":1534155867000},"page":"1912-1922","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":16,"title":["Photovoltaic tied unified power quality conditioner topology based on a novel notch filter utilized control algorithm for power quality improvement"],"prefix":"10.1177","volume":"41","author":[{"given":"Santanu Kumar","family":"Dash","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, National Institute of Technology, Rourkela, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1992-4011","authenticated-orcid":false,"given":"Pravat Kumar","family":"Ray","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, National Institute of Technology, Rourkela, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,8,13]]},"reference":[{"key":"bibr1-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2009.2014369"},{"key":"bibr2-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1515\/ijeeps-2016-0143"},{"key":"bibr3-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1515\/ijeeps-2016-0021"},{"key":"bibr4-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/INDICON.2015.7443684"},{"key":"bibr5-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/IAS.2016.7731860"},{"key":"bibr6-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/ICPEICES.2016.7853162"},{"key":"bibr7-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1177\/0142331215622810"},{"key":"bibr8-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1049\/iet-gtd.2015.0684"},{"key":"bibr9-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1177\/0142331217695402"},{"key":"bibr10-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/61.997949"},{"key":"bibr11-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/TPWRD.2010.2064341"},{"key":"bibr12-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4615-1153-3"},{"key":"bibr13-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1049\/iet-rpg.2013.0251"},{"key":"bibr14-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2011.2172001"},{"key":"bibr15-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1049\/iet-pel.2010.0031"},{"key":"bibr16-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2013.2245622"},{"key":"bibr17-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/TSTE.2016.2570256"},{"key":"bibr18-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-36321-4_63"},{"issue":"5","key":"bibr19-0142331218790314","first-page":"585","volume":"34","author":"Paul PJ","year":"2011","journal-title":"Transactions of the Institute of Measurement and Control"},{"key":"bibr20-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/ECCE.2016.7854707"},{"key":"bibr21-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/TPWRD.2009.2034902"},{"key":"bibr22-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/28.62384"},{"key":"bibr23-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1109\/TENCON.2008.4766507"},{"key":"bibr24-0142331218790314","doi-asserted-by":"publisher","DOI":"10.1504\/IJAAC.2009.025242"},{"key":"bibr25-0142331218790314","unstructured":"Texas Instruments (2004) CMOS Hex Voltage Level Shifter for TTL to CMOS or CMOS to CMOS Operation.
