Total transmission power is an important indicator of any system interfaces used to maintain system stability in a market environment. Information about the total transmission power for power systems management used. In addition, total trans- missionpowerdailyorevenhourlytoestimatethereliabilitymarginsforallpower transmissions through the interfaces of each network. According to the proposed approach,usersspendtheirtimesettingupandpreparingbigdataforcalculations. Thisapproachsignificantlyreducesthenumberoferrorsofoperationalstaffwhen performing calculations. To optimize the modes of operation of the transmission line,proposedtosolveproblemsofvoltageandreactivepoweroptimization.Power lines operating mode monitoring consists of correct choice of the composition of the charging power compensation devices in order to regulate the voltage levels andpowercoefficientsatthebusterminals.Byusingmoderndevicesforcontrolled compensation of power line charging, it is possible to achieve deeper regulation of reactive power and voltage, and, accordingly, to minimize the loss of active power. Interconnected mathematical models set to determine the economic effect ofoptimizingthemodeofoperationoftheelectricalnetworkwithultra-highpower lines in terms of voltage and reactive power, taking into account the probabilistic natureofcoronalosses.Methods,algorithmsandmethodsofoperativeoptimization of operating modes of separate power lines taking into account corona losses are developed.

The chapter presents theoretical substantiations of models for assessingtheimpactofnetworkconstraintsontheexchangeofelectricitythroughthe electricsectiononthepricingprocessesintheelectricityday-aheadmarketsegment onthebaseofthedecentralizedmarketcouplingconcept.Ageneraldescriptionofthe existingmethodsofcongestionmanagementformarketcouplingisgiven.Oneofthe mostimportantandactualtasksofoperabilityassuranceoftheday-aheadmarketis todeterminethecross-bordercongestionmanagementmethods.Thelatterapproach ismorepromisingandactivelydevelopingnow.Themostknownimplementationsof marketcouplingaretheflow-basedmarketcoupling(FBC)anddecentralizedmarket coupling(DMC),includingtrilateralmarketcoupling(TMC).ThemainFBCdisad- vantageisthenecessityoflinearizationofelectricitydemandfunction.Itprevents fromadequatelytakingintoaccountthedemandandofferstructure,whichisgener- atedfromlinearanddiscretetypebids.Asaresult,thewrongchoicesofincrement of iterative process and the missing of the global extremum are possible. DMC uses mathematical apparatus of net export curves (NECs), which correctly reflect the potential of the export and import of electricity for a local market area in the common electricity market. However, the use of NEC is complicated in case of a coupling of more than two electricity markets. Also, there is the problem of the formalpresentationofrelationsstructurebetweenthecouplingmarkets.Approaches totheanalysisofrestrictionsontheexchangeofelectricitybyelectriccross-section asataskofmulti-purposeoptimizationofthewelfarefunctionofelectricitymarket participantsareformalized.Methodsandmodelsofanalysisofprocessesofdecen- tralized market coupling of a group of price zones of free configuration are given.
