A transformer less hybrid series active filter is proposed to enhance the power quality in singlephase systems with critical loads. This thesis assists the energy management and power quality issues related to electric transportation and focuses on improving electric vehicle load connection to the grid. The control strategy is designed to prevent current harmonic distortions of nonlinear loads ...

This paper presents a new approach for determining the effective control signals for damping of oscillations by performance comparison of Unified Power Flow Controller in coordination with Power Oscillation Damping Controller and Power System Stabilizer. For the analysis Modified Phllips-Heffron Model of Single Machine Infinite Bus system is established with Unified Power Flow Controller. Impac...

To improve the primary frequency response in future low-inertia hybrid power system a fuzzylogic based frequency controller (FFC) for wind farms augmented with energy storage systems(wind-storage system) and intelligent PV farms for the frequency stabilization is proposed inthis paper. Using system frequency deviations the proposed controller provides bidirectionalreal p...

In this paper, a D-Q model of fuzzy based unified power flow controller (UPFC) has been proposed to control the active and reactive power flow through the transmission lines. Power loss reduction also intends with the proposed UPFC controller. The UPFC’s shunt and series controllers are developed based on D-Q fuzzy logic (FL) controller, which has been designed in PSCAD environment as an indepe...

-In this paper, multi-objective optimal placement (MOOP) of multi-type flexible AC transmission systems (FACTS) devices for Thailand power system is proposed. Four types of FACTS devices are used: thyristor-controlled series capacitor (TCSC), thyristor-controlled phase shifter (TCPS), unified power flow controller (UPFC), and static var compensator (SVC). The problem is decomposed into the opti...

The design of Automatic Generation Control (AGC) system plays a vital role in automation of power system. This paper proposes Hybrid Neuro Fuzzy (HNF) approach for AGC of two-area interconnected reheat thermal power system with the consideration of Generation Rate Constraint (GRC). The advantage of proposed controller is that it can handle the system non-linearities and at the same time the pro...
