“…The power system quality is mainly measured depending on the total harmonic distortion (THD). Both power electronic devices and nonlinear loads inject distorted currents and hence increase the THD at the MG. 30 The increased THD results in MG overheating, system instability, transmission, and distribution losses increasing and protection system failure. 6,31 To reduce the THD to its acceptable limits, filters are applied for harmonic mitigation.…”

Summary This paper proposes a novel methodology for controlling voltage and frequency of islanded microgrids and meanwhile improving the system power quality. The proposed methodology is based on applying a multi‐stage H‐Infinity (H∞) controller with different control loops to restore the nominal values of voltage and frequency after any load variation. These control loops include power control, current control, and voltage control loops. The H∞ is also applied with an LCL filter to enhance the system power quality. The proposed controller is applied to a test system under three different loading conditions and the obtained results are compared with that obtained by applying the model predictive control (MPC) method. The results are compared with that obtained by applying a proposed traditional control method in the same test system. A comparison between the droop controller and the proposed controller, MPC is performed based on fitness value, controller response time, and maximum frequency deviation. In addition, the system stability is analysed using root locus, system step response, singular value decomposition, and bode diagram. The results prove the effectiveness and the efficiency of the proposed method in restoring voltage and frequency and improving the system power quality.

The study done in this paper concerns the use of a new control technique of current using adaptive hysteresis regulator by fuzzy logic on the command of a parallel active filter. For the proposed method, the hysteresis band is adapted in every moment in order to determine the switching frequency and control the position of the command pulses. This allows a better tracking of a heavily distorted current and minimizes undulations in the various quantities characterizing the active power filter. In this paper, the theory of the method is discussed and its performance is compared, though out simulations, to the adaptive band technique. The comparative study confirms the benefits and potentiality of the new modulation method.

“…Improving the power quality is an important objective for smart grids and an important characteristic is the voltage waveform. There are various events that affect the power quality in the distribution systems and the presence of nonlinear loads introduces harmonics, responsible for the degradation of the waveform [3].…”
