In this paper, the optimal design of supplementary controller parameters of a unified powerflow controller(UPFC) for damping low-frequency oscillations in a weakly connected systemis investigated. The individual design of the UPFC controller, using hybrid particle swarmoptimization and gravitational search algorithm (PSOGSA)technique under 3 loadingoperating conditions, is discussed. The effect...

In this paper, the Unified Power Flow Controller (UPFC) is enhanced with a Chaotic Particle Swarm Optimization (CPSO) Damping Controller in order to mitigate the Low Frequency Oscillations (LFO) in a Single Machine Infinite Bus (SMIB) power system. The designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...

Abstract In this paper, a novel hybrid technique is proposed for transient stability analysis on grid connected Wind-Diesel-PV system. The methodology combination of the dwarf mongoose optimization algorithm (DMO) and recalling enhanced recurrent neural network (RERNN) named DMO-RERNN. main purpose work to consider various elements system according different conditions. voltage profile using un...

<p>The Power quality of the electrical system is an important issue for industrial, commercial, and housing uses. An increasing request high power number distorting loads had led to increase consideration by customers utilities. The development use flexible alternating current transmission (FACTs) controllers in systems many applications these controllers. A unified flow controller (UPFC)...

Abstract Conventional phase‐shifting transformers (PST) have been utilized for power flow control in transmission networks many years. Compared to the slow reacting PSTs, recently trending unified controllers (UPFC) enable much faster control. This paper introduces a decentralized scheme (PFCs) without need communication between PFCs. For each PFC, an influence area is defined. The line loading...

in emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. the flexible ac transmission system (facts) controllers can play an important role in the power system security enhancement. however, due to high capital investment, it is necessary to locate these controllers optimally in the power system. facts...

To investigate the effect and ability of FACTS devices using Fast Flexible Holomorphic Embedding technique (FFHE), it is necessary to develop an embedded system for these devices. Therefore, this paper presents FFHE based STATCOM UPFC. The also proposed their controlling modes. introduced UPFC flexible which allows take any state as initial guess instead fixed state, leads towards reduced runti...
