The power system is a network that consists of generation, transmission and distribution system. The power plants, transformers, transmission lines, substations, distribution lines, and distribution transformersarethesixmaincomponentsofthepower system. The generator generates the power which is step up or step down through the transformer for transmission. The transmission system carries the overhead lines which transfer the generated electrical energyfromgenerationtothedistributionsubstations. Distribution systems connect all the consumers in an areatothebulkpowersources.

Abstract The electrical power system consists of generation, transmission, distribution system. The transmission system links the generators to substations, which supply power to the user through the distribution system. The Distribution system is most associated with power loss and has least reliability due to various reasons such as low voltage levels and multiplicity of faults. This workisapplyingparticleswarmoptimization algorithm (PSO) that aims to achieve the power loss reduction and maximum voltage profile in radial distribution network with Distribution Static Compensator (D STATCOM). D STATCOM is used to improve bus voltage profile. Voltage stability index is used to identify place for placing D STATCOM. An effectivelyparticleswarmoptimization is usedtosearch the best location and is employed to deduce the size and location of D STATCOM for the weak buses. The validity of the method is tested in the IEEE12,IEEE34 Bus radial CheckanuraniandandwithoutobtainedperformedofdistributionsystemandCheckanuranisubstationrating110/11KVinMadurai.LoadflowanalysisisandthebusvoltageandpowerlossisinMATLAB.TheresultsobtainedarecomparedandwithDSTATCOM.BytheoptimalplacementsizingofDSTATCOMthevoltageprofileimprovedthepowerlossreductionsareobtainedinthesubstationlocatedinMadurai,Tamilnadu.

OPTIMAL SITING AND SIZING OF D-STATCOM USING PARTICLE SWARM OPTIMIZATION
Distribution systems have high R/X ratio which results in high power loss which leads to voltage instability.Seriesvoltageregulatorandshuntcapacitors are the two conventional ways of maintaining the voltages of the distribution system at an acceptable range.But,thesedeviceshavesomedisadvantagesthat are conventional series voltage regulators cannot generatereactivepowerandhavequiteslowresponse because of their step by step operations. The disadvantage with the shunt capacitors is that they cannotgeneratecontinuouslyvariablereactivepower.

This work presents an efficient approach for the placement of D STATCOM in radialdistributionsystem.Voltagestabilityindexvaluesfor allthebusesaredeterminedtofindtheoptimalbuswhichis selectedascandidatebusforplacementofDSTATCOM.The D STATCOM is modelled by calculating injected reactive power for different reference voltages. Particle swarm optimizationalgorithmisusedtofindsizingofD STATCOM. The resultant reactive power for IEEE12 bus is 92.3716 KVAR,IEEE34 bus is 448.1481KVAR and Karumathar is 1KVAr,Gandhinagar0.047KVAr,Thenpalanji0.1609KVAr, Kannanur150.4478KVAr.Again,theloadflowanalysisis performedbycompensatingthereactivepowerandvoltage phase angle. The improved bus voltage for IEEE12 bus is 0.9655,IEEE34busis0.9140puandKarumathuris0.9609 pu, Gandhinagar 0.9259pu, Thenpalanji 0.9907 pu, Kannanur 0.9440 pu. The reduced power losses for the IEEE12,IEEE34busesare12.4KW,94.0341KWandfeeders are320KW,43.2KW,388.8KW,and6494KWrespectively. The result shows the improvement in voltage profile and reduction in power losses. In future, ANN or Fuzzy logic could be used to adjust the rating of DSTATCOM for variationsinloadoranycontingencycases.
