“…According to the advantages of multilevel converters in power quality applications and CMCs in particular, this paper recaps the design and simulation of CMC-based multilevel STATCOM for load voltage regulation. Compared to the previous control strategies [14][15][16][17], the proposed method has a higher performance for power quality improvement and is comparatively easy and has high practical value with easy hardware implementation. In the second section, investigation of factors affecting passive components of CMC-based multilevel STATCOM and its power circuit design to regulate the load voltage is done.…”

Static synchronous compensators (STATCOM) are increasingly implemented in power systems. Moreover, cascaded multilevel converters (CMC) are more frequently taken in consideration because of their strong capabilities. In this paper, the design and simulation of a multilevel STATCOM for voltage regulation of load is presented. Design of the passive components, active and reactive power controller, and balancer of capacitor voltage are parts of proposed system design. The pole placement method was used for the design of the controller. Simulation results with MATLAB/SIMULINK show good performance of voltage regulation in full load and dynamic load conditions. ABSTRAK: Penyelaras pengimbang statik (STATCOM) semakin dilaksanakan dalam sistem kuasa. Selain itu, penukar pelbagai aras tingkatan (CMC) lebih diutamakan kerana mempunyai banyak kelebihan. Dalam kajian ini, reka bentuk dan simulasi bertingkat STATCOM bagi pelbagai voltan beban dibentangkan. Reka bentuk komponen pasif, penyelenggara kuasa aktif dan reaktif dan pengimbang voltan kapasitor adalah sebahagian daripada sistem yang dicadangkan. Bagi reka bentuk penyelenggara, kaedah penempatan titik telah digunakan. Hasil simulasi melalui MATLAB/SIMULINK menunjukkan keputusan yang baik pada regulasi voltan pada beban penuh dan pada keadaan beban dinamik.

“…Studies like presented in [11] use the self‐tuning of PI controllers by means of the steepest descent method in order to minimise the response given by a critic‐based method, however, requiring a first iteration of gains provided by the operator, requiring the knowledge of the grid's initial parameters. The one proposed in [12] uses a fuzzy logic algorithm to adjust the controller during operation, but needing a starting point by using the Ziegler–Nichols method, thus, requiring the operator's interference in the beginning. An adaptive control strategy was proposed in [13], where the PI gains were analytically tuned online based in the estimated inductance of the system.…”

This work presents a plug‐and‐play solution for voltage source converters controlled by proportional–integral controllers to automatically operate connected to a previously unknown grid. The methodology consists of an initial operation using hysteresis band current control in order to synthesise harmonic currents, which are used for online grid parameter estimation, allowing the proper analytical tuning of the controllers using the grid's equivalent model. The method is firstly simulated and then validated through experimental results using Texas Instruments TMS320F28377S Digital Signal Processor and BOOSTXLDRV8305‐EVM static converter.

“…It allows tuning controllers to achieve a high efficiency of power grid operation. Fuzzy logic is a powerful mathematical tool for power system control [2,3] but applying Fuzzy Logic requires expert knowledge of the system and its functioning. Therefore, developing fuzzy rules can be very time-consuming.…”

Optimization of a power supply system is one of the main directions in power engineering research. The reactive power compensation reduces active power losses in transmission lines. In general, researches devoted to allocation and control of the compensation units consider this issue as a static optimization problem. However, it is dynamic and stochastic optimization problem that requires a real-time solution. To solve the dynamic optimization NP-hard problem, it is advisable to use Swarm Intelligence. This research deals with the problem of the compensation units power control as a dynamic optimization problem, considering the possible stochastic failures of the compensation units. The Particle Swarm Optimization and the Bees Algorithm were applied to solve it to compare the effectiveness of these algorithms in the dynamic optimization of a power supply system.
