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-

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

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
