TTF index computation considering reactive power flows

摘要

Besides the risk of element outage, biggest risk to power system security and safe work is occurrence of congestion. The occurrence of congestion is a result of limited network transfer capacities on cross-border lines as well as the transfer capacities in the network itself, as result of increased power transactions. With power market implementation, low-cost generators gain their advantage over expensive ones, which resulted in increasing of planned cross-border power exchange. Transmission System operators (TSO) implemented defensive measures to mitigate congestion, but still rests as problem and cancelling or lowering the power transactions should be no solution.
