Single Phase Shunt Active Power Filters, Proportional-Resonant Controller, Genetic Algorithms, Indirect Current ControlAbstract
Nowadays, more attention has been paid to power quality of electricity. The advance in electrical equipment and power electronics causes harmonics in the electrical system. Harmonics can cause damage and malfunction of the equipment in the system. Shunt active power filters is one of effective devices used for improving power quality by harmonic filtering. This paper proposes optimized design of proportional-resonant (PR) controller for single-phase shunt active power filtes based on indirect current control technique. Controller parameters are obtained through the use of Genetic Algorithms (GA). The validation of the proposed control is done through simulations. The results show that %THD is reduced to less than 3% which complies with IEEE Standard 519-2014.
