A electric power system have numerous components utilized in generation, transmission and distribution systems; due to its complex structure a major issue of stability, frequency maintain, power instability in tie-lines and cascading failures exists. To deal with these problems, power electronics based devices: flexible AC transmission system (FACTS) and distributed-FACTS (D-FACTS) devices are placed on optimal location. This paper represents load flow methods: Newton-Raphson method, Gauss-Seidel method, Fast-Decoupled method, FACTS devices (static synchronous series compensation, unified power flow controller) and D-FACTS devices, used for calculating different line parameter for IEEE 14, 30 and 57 bus system. These methods have varying qualities: convergence, accuracy, reliability, stability etc. The simulation outcomes show comparative analysis of active power, reactive power under steady state condition through different IEEE bus system. |
