Tutorial Title: Power Qualities and Their Compensators in Distributed Power Generation Systems

With the proliferation and development of voltage-sensitive load equipment in diverse industries such as semiconductor fabrication houses, automatic production lines, large data centers, pharmaceuticals, hospital equipment, and so on, their processes have become much more vulnerable to degradation in the quality of power supply. Power quality (PQ) problems in the form of voltage sag, voltage harmonic, voltage swell, and voltage flicker can cause severe process disruptions, resulting in substantial economic and/or data losses. On the other hand, the increase usage of the power electronics devices and motor loadings (such as: converters, adjustable speed drives, bulk rectifiers, power supplies, elevators, large air conditioning systems, etc.), and also rapid increase in renewable energy generator in power grid, the current quality problems also become more serious, especially for lower power factor, harmonic pollution, unbalanced current, etc., which strongly affects the performance, efficiency and reliability of the power grid. Therefore, implementation of power filters is one of the effective solutions for solving the aforementioned PQ problems. In this presentation, the PQ issues, its impacts and standards to govern different PQ problems will be introduced. The basic principles of series and parallel PQ compensators for mitigating the voltage and current quality problems will be presented. In addition, the design, control and analysis of the series and parallel active PQ compensators will be discussed in details. Then, the advanced control and coordination of LC-coupling hybrid active power filters and the advanced control of the newly developed TCLC-coupling hybrid active power filter will be presented. Finally, the recent research trends of PQ compensators will be introduced.
