This paper proposes to utilize intentional time delays as part of controllers improve the damping electromechanical oscillations power systems. Through stability theory, control parameter settings for which these in Power System Stabilizers (PSSs) small signal a system are systematically identified, including key regions plane remain connected effective operation.

This work suggests a type-2 fuzzy lead–lag (T2FLL) controller structure for flexible AC transmission system (FACTS)-based damping controllers and power stabilizers (PSSs) stability improvement. The values of the suggested are optimized by hybrid adaptive differential evolution pattern search algorithm (hADE-PS) method. Initially, single-machine infinite-bus (SMIB) with (LL)-structured FACTS PSS...

This paper proposes a static synchronous series compensator based on H-bridge inverter modules. Dynamic response of proposed system was analyzed by EMTP simulation, assuming that it is inserted in the 154-kV transmission line of one-machine-infinite-bus power system. The proposed system consists of 6 H-bridge inverter modules per phase, which generate 13 pulses for each half period of power fre...

This paper considers the stabilization of a synchronous machine connected to an infinite bus via a PID. The PID parameters are tuned using hybrid Particle Swarm-Bacteria Foraging Optimization (PSO-BFA). Simulation results are introduced with and without the proposed controller. Also, a comparison study is introduced when using classical PID, only bacteria foraging optimization and when using hy...

This paper considers the decentralized turbine-governor control design for the damping of low-frequency, inter-area oscillations in electric power systems. A time-varying model that explains oscillations caused by parametric resonance is employed to design a controller. A robust turbine-governor controller design is presented on the basis of the model. Furthermore, a basic idea for incorporatin...

the digital redesign technique is one of the most popular approaches to the design of digital controllers in industries. Which converting a good-designed continuous time controller to a digital controller suitable for digital implementation. In this paper, the Plant-Input-Mapping algorithm (PIM) is used for converting the S-domain model of the PID controller to a Z-domain model counterpart. The...

This paper offers novel non-linear control of a doubly fed induction generator (DFIG) and unified power flow controller (UPFC) for transient stability increment with energy function (TEF) sliding mode observer in system. First, the TEF technique is considered damping system synchronous (SG), DFIG, UPFC, then time-derivative signals are estimated by second-order observer. The importance issue em...

In this paper a Multi-objective Honey Bee Mating Optimization (MOHBMO) technique is applied to damp power system oscillation by tuning the Power System Stabilizer (PSS) parameters. Selecting the parameters of PSS which simultaneously stabilize system oscillations is converted to a simple optimization problem which is solved by a HBMO. In the proposed syndicate tuning technique, two performances...

Power System Dynamics Course (PSDC) is one of the most important courses in the MSc/M.Tech program of Electrical Engineering at most of the universities worldwide. However, due to the difficulties exist in this course, students are unable to learn the power systems dynamics, properly. This paper introduces a tool based on MATLAB Software that is useful for educating PSDC, effectively. A tool ba...
