This paper presents a new population based parameter free optimization algorithm as teaching learning based optimization (TLBO) and its application to automatic load frequency control (ALFC) of multi-source power system having thermal, hydro and gas power plants. The proposed method is based on the effect of the influence of teacher on the output of learners and the learners can enhance their k...

Back-to-back static synchronous compensator (BtBSTATCOM) consists of two back-to-back voltage-source converters (VSC) with a common DC link in a substation. This configuration extends the capabilities of conventional STATCOM that bidirectional active power transfer from one bus to another is possible. In this paper, VSCs are designed in quasi multi-pulse form in which GTOs are triggered only on...

A multi objective Honey Bee Mating Optimization (HBMO) designed by online learning mechanism is proposed in this paper to optimize the double Fuzzy-Lead-Lag (FLL) stabilizer parameters in order to improve low-frequency oscillations in a multi machine power system. The proposed double FLL stabilizer consists of a low pass filter and two fuzzy logic controllers whose parameters can be set by the ...

The Interline Power Flow Controller (IPFC) is one of the Voltage Source Converter (VSC) based facts controllers which can effectively manage the power flow via multi-line transmission system. In this paper a new method for control of IPFC, with the aim of managing the power flow in transmission lines is presented. Simplicity and fast system response are two characteristics of this method. An IP...

The performance of load frequency control (LFC) for isolated multiple sources electric power-generating units with a proportional integral derivative (PID) controller is presented. A thermal, hydro, and gas unit are integrated into the studied system. PID proposed as subordinate to stabilize system when there sudden demand on power particle swarm optimization (PSO) algorithm used obtain optimal...

To ensure the safe operation of an interconnected power system, it is necessary to maintain stability frequency and tie-line exchanged power. This one hottest issues in system field usually called load control. overcome influences disturbances on multi-source systems containing thermal plants, hydropower gas turbine we design a linear active disturbance rejection control (LADRC) based bias mode...
