Design and analysis of two degree of freedom tilt integral Derivative Controller with filter for frequency control and real time validation
Journal of Electrical Engineering, 2020Co-Authors: Jagan Mohana Rao Chintu, Rabindra Kumar Sahu, Sidhartha PandaAbstract:AbstractTo deliver steady electric power with decent quality, intelligent and healthy control schemes are greatly necessary for automatic generation control (AGC) of power systems therefore, this work presents the design of two degree of freedom based tilt integral Derivative Controller with filter for AGC. Firstly, a two-area reheat thermal model is considered, and the gain of the Controller are optimized by adaptive differential evolution method. The advantage of the suggested approach is validated by equating results with latest published approaches such as symbiotic organism search algorithm and articial bee colony tuned PID Controller. Further, the suggested method is extended to a three unequal area thermal model and the performance of results are equated with teaching-learning based optimization-PIDD and firey algorithm-PID for the identical model. Lastly, the experiment of the proposed scheme has been employed in real-time simulation using OPAL-RT, for validation of its viability and cogency.

design and analysis of tilt integral Derivative Controller with filter for load frequency control of multi area interconnected power systems
Isa Transactions, 2016Co-Authors: Rabindra Kumar Sahu, Sidhartha Panda, Ashutosh Biswal, G Chandra T SekharAbstract:In this paper, a novel Tilt Integral Derivative Controller with Filter (TIDF) is proposed for Load Frequency Control (LFC) of multi-area power systems. Initially, a two-area power system is considered and the parameters of the TIDF Controller are optimized using Differential Evolution (DE) algorithm employing an Integral of Time multiplied Absolute Error (ITAE) criterion. The superiority of the proposed approach is demonstrated by comparing the results with some recently published heuristic approaches such as Firefly Algorithm (FA), Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) optimized PID Controllers for the same interconnected power system. Investigations reveal that proposed TIDF Controllers provide better dynamic response compared to PID Controller in terms of minimum undershoots and settling times of frequency as well as tie-line power deviations following a disturbance. The proposed approach is also extended to two widely used three area test systems considering nonlinearities such as Generation Rate Constraint (GRC) and Governor Dead Band (GDB). To improve the performance of the system, a Thyristor Controlled Series Compensator (TCSC) is also considered and the performance of TIDF Controller in presence of TCSC is investigated. It is observed that system performance improves with the inclusion of TCSC. Finally, sensitivity analysis is carried out to test the robustness of the proposed Controller by varying the system parameters, operating condition and load pattern. It is observed that the proposed Controllers are robust and perform satisfactorily with variations in operating condition, system parameters and load pattern.

tuning and assessment of proportional integral Derivative Controller for an automatic voltage regulator system employing local unimodal sampling algorithm
Electric Power Components and Systems, 2014Co-Authors: Pradeep Kumar Mohanty, Binod Kumar Sahu, Sidhartha PandaAbstract:Abstract—This article presents an approach for obtaining proportional–integral–Derivative Controller parameters for an automatic voltage regulator system based on a local unimodal sampling optimization algorithm. A conventional integral time of squared error objective function and modified objective functions in terms of integral time of absolute error, integral of absolute error, integral of squared error, peak overshoot, and settling time with appropriate weighting factors are employed to tune the Controller parameters. Different objective functions are employed to obtain optimized proportional–integral–Derivative Controller gains. Superiority of proposed technique over some recently published modern heuristic optimization techniques, such as artificial bee colony algorithm, particle swarm optimization algorithm, and differential evolution algorithm, for the same automatic voltage regulator system is demonstrated. Simulation results reveal that the proposed proportional–integral–Derivative controlled au...

Differential evolution algorithm tuned tilt integral Derivative Controller with filter Controller for automatic generation control
Evolutionary Intelligence, 2019Co-Authors: Rabindra Kumar Sahu, G. T. Chandra Sekhar, Sonali PriyadarshaniAbstract:A differential evolution (DE) tuned tilt integral Derivative Controller with filter (TIDF) has been implemented to a multi area reheat thermal power system for automatic generation control by taking the physical constraints like generation rate constraint and governor dead band nonlinearity. Initially, dissimilar integral Controllers are considered in each area and the integral Controller gains have been optimized by integral of time multiplied by absolute value of error (ITAE) criterion exploiting different strategies of DE algorithm. In next step, the control parameters such as step size and crossover probability of DE for the best strategy can be chosen with multiple iterations of the algorithm systematically for variation in each control parameter and DE proposes the control parameters. Further, PI/PID/TIDF type Controller schemes have been modified and their gains have been optimized by optimal DE. Furthermore, to improve the transient system response, TIDF Controller coordinated unified power flow Controller (UPFC) has been investigated. The simulation results reveal that the minimum ITAE value is obtained when UPFC is placed in area-5 only. Finally, sensitivity analysis has been done by changing the operating load conditions along with the time constants of system parameters, from the simulation results it has been examined that there is no need to reset the Controller parameters from their nominal setting for these variations. The proposed control scheme effectiveness is also observed by considering random step load disturbance and sinusoidal load disturbance.

Fractional order proportional Derivative control for time delay plant of the second order: The frequency frame
Journal of the Franklin Institute, 2020Co-Authors: Bilal Şenol, Uğur Demiroğlu, Radek MatušůAbstract:Abstract This paper intends to tune fractional order proportional Derivative Controller for the performance, stability and robustness of second order plus time delay plant. The tuning method is based on the previously proposed “frequency frame” which is a rectangular frame enclosing gain and phase margins limited with gain and phase crossover frequencies in the Bode plot. Edges of the frame are tuned to achieve desired crossover frequencies and margins. By shaping the curves of the Bode plot, improvements are observed in the performance and robustness of the second order plus time delay system controlled by a fractional order proportional Derivative Controller. Generalized equations to obtain the parameters of the fractional order proportional Derivative Controller for second order plus time delay plant are given. In contrast to existing studies, this method reduces mathematical complexity when providing desired properties. Three examples are considered and effectiveness of the frequency frame is shown.

analysis of a nonlinear magnetic levitation system vibrations controlled by a time delayed proportional Derivative Controller
Nonlinear Dynamics, 2015Co-Authors: M Eissa, Ali Kandil, W A Elganaini, M KamelAbstract:A time-delayed proportional-Derivative Controller is proposed in this paper to reduce the horizontal vibration of a magnetically levitated system having quadratic and cubic nonlinearities to primary and parametric excitations. Applying multiple scales perturbation technique, a second-order approximate solution is sought to analyze the nonlinear behavior of the system. The effects of the time delay are studied to indicate the stable range of time delays for the best performance. The results are compared with the numerical simulations, and this shows a good verification for the approximate solution and for the control algorithm used in this paper. A comparison with previously published work is included at the end.
