“…Therefore, modification in procedures are shifting toward the soft computing method. There are a lot of soft computing techniques used to tune the gains and time constant of the PI or PID controller (Stojic et al, 2017). Some examples are simplex algorithm (Gole et al, 2003;Zhao et al, 2007), linear programing based tuning (Oliveira et al, 2014), Modified Genetic Algorithm (Y. P. Wang et al, 2002), offline tuning of discrete-time fractional-order to minimize the cost function (Merrikh-Bayat et al, 2015), Hybrid PID-Artificial Neural Network (ANN) controller to control PWM signal for DC to DC conversion (Muruganandam and Madheswaran, 2013), fuzzy logic algorithm (Sahin and Altas, 2017;Ilyas et al, 2013;Kassem, 2013), State Transition Algorithm (STA) (Saravanakumar et al, 2015), Particle Swarm Optimization (PSO) (Aazim et al, 2017;Rajagopal and Ponnusamy, 2014), etc.…”

This work aims to tune multiple controllers at the same time for a HVDC system by using a self-generated (SG) simulation-based optimization technique. Online optimization is a powerful tool to improve performance of the system. Proportion integral (PI) controllers of Multi-infeed HVDC systems are optimized by the evaluation of objective functions in time simulation design (TSD). Model based simulation setup is applied for rapid selection of optimal PI control parameters, designed in PSCAD software. A multiple objective function (OF), i.e. Integral absolute error (IAE), integral square error (ISE), integral time absolute error (ITAE), integral time square error (ITSE), and integral square time error (ISTE), is assembled for testing the compatibility of OFs with nonlinear self-generated simplex algorithm (SS-SA). Improved control parameters are achieved after multiple iterations. All OFs generate optimum responses and their results are compared with each other by their minimized numerical values. Disturbance rejection criteria are also proposed to assess the designed controller performance along with robustness of system. Results are displayed in form of graphs and tables in this paper.

“…In this case, the cross products of ac components have a non-null average value. Expression (40) allows to control the W ∆T energy using either I AC 1 , I AC 3 or any I DC 123 currents, but the I AC 1 current is used in this paper. Applying the same process used to obtain (38), the expression (43) is obtained.…”

DC-DC converters are needed for the future development of high voltage direct current (HVDC) grids, as they allow to interconnect lines with different voltages and topologies. The dc-dc converters can increase the grid controllability adding power flow control, voltage regulation and/or fault blocking capability. The dc modular multilevel converter (dc-MMC) is a non-isolated solution proposed to interconnect HVDC systems with the same line topology. This paper proposes a new dc-MMC with a control strategy, which allows the converter to interconnect different line topologies (e.g., rigid bipole connected to a symmetric monopole). The paper presents the different line topologies in HVDC installations. Then, a mathematical model with a variable transformation is proposed for the new dc-dc converter. A control structure is proposed and implemented in Matlab/Simulink using an average arm model and simplified dc grids. The results validate the control in normal operation, fault blocking capability and post-fault scenario (degraded mode).

“…In this, the current from source and point of common coupling (pcc) should follow each and are to be in phase with each other. The P-Q, SRF, and UPF methods are used in perfect harmonic compensation method 9 for compensating the harmonic currents eliminating the unbalance condition. SAF controlled by linear Quadratic Regulator 7 -based switching controller was developed for harmonic mitigation also provides solution for parallel resonance problem.…”

“…This multilevel SAF is controlled by fuzzy to improve the voltage behaviors of the floating capacitors at dynamic and steady state. Reduced Order Generalized Integrator (ROGI), 10 FLC, 11 and PR-Proportional Resonant Controller 9 are the proposed control techniques used in Space vector modulation (SVM) technique. ROGI controller 10 computations are less by 50% than the second order generalized integrator 12 and can be applied under stationary reference frame without transformation to rotational coordinate system.…”

The increased use of electronics for control and use of nonlinear type loads by consumers in the present power system network are injecting harmonics into the power signal, due to which the power quality issue has become more challenge for the present researchers.In this work, the reduced order generalized integrator (ROGI) and fuzzy logic control (FLC) are collectively used to reduce the current harmonics in the power system. FLC-SVM technique is used to maintain the process of SAF-Shunt active filter with fixed switching frequency. This proposed control technique consists of control loop for current to have fast and effective control. The Proportional Resonant controller is used to have control on voltage for a slow and effective control process which is also used to compensate reactive power. The shunt active filter is designed with the help of ROGI by integrating PI controller for fuzzy-based SVM to reduce the current harmonics on the load side. The results are achieved in MATLAB/SIMULINK software.
