Heavy loading conditions studies by optimal UPFC on a real Finnish 110 KV network to solve technical problems of 2020

Unified Power Flow Controller (UPFC) has effective options to deal with most of the technical problems in the power system operation. This ability gives to UPFC the power to control the voltage profile and the transmission lines flow simultaneously. In this paper, we define the optimal locations and settings of UPFC using the Genetics Algorithm (GA) to solve real technical problems in a real Finnish network, Helsinki HELENSAHKOVERKKO OY 110 KV NETWORK, specially solving the transmission lines overloading at heavy loading operations of Year 2020.
