Quantifying TRM by Modified DCQ Load Flow Method

In the integrated power system network uncertainty can occur at any time. The transmission reliability (TRM) margin is amount of capacity that guarantees protected from instability in operating state system. calculation available transfer (ATC) should be included a deregulated to ensure safe within fair range uncertainties arise during transfer. However, TRM conserved as reflect unpredictability operation electric Besides, operator (SO) utilizes value unreliability by adjusting ATC some up or down account for errors data and model. This paper describes technique estimation modified DCQ load flow method considering VAR distribution factor. main focus this study get new approach determine incorporating with ATCQ considered reactive sensitivity w.r.t voltage magnitude. applied IEEE 6 bus system, results are compared previous validation. leads more exact secure estimates margin.
