Customized power quality service provided by converter interfaced microgrids — Voltage harmonics as a study case

Customers may have different power quality requirements, thus, the economic operational strategy can try to provide them with distinctive quality levels as customized service. An optimization based method is proposed in this paper to realize this functionality, offering the possibility that the customers can flexibly set and adjust their requirements. Converter interfaced distributed generators are used as compensators. Simulation results show that the proposed method is able to limit the voltage harmonics at each bus within respective limits.
