摘要: The proliferation of semiconductor-based nonlinear devices in power systems has caused serious concern over quality issue. This paper proposes a decentralized control strategy for multiple active front-ends (AFEs) so that harmonic currents as well reactive generated by the load can be compensated. Under proposed strategy, each front-end autonomously decides its share improvement task, which is bounded converter rating and dynamically adjusted machine loading condition. uncompensated an will left other units on source side to compensate. In this way, overall task automatically distributed without communications. order verify theoretical analysis fully carried out detailed simulation studies using switching-level models are performed.
