“…It is accountable for the safety of the power inverter besides the overloading and enrichment of the power network robustness. 67 Additionally, the current loop matches the base current with inverter response current, lessens the error value and provide links to reference compensation values (u Ã d and u Ã q ). The reference values of voltage produced by the inner control block are represented in the rotating dqo reference frame.…”

This paper endeavours a control scheme for optimal control of voltage and frequency of power inverter which relied upon distributed generation in cognitive microgrid using soft computational methods. It gives sound direction on how to control the active power flow, voltage-frequency regulation, and sharing of power among various components of MG. The classical voltage-frequency control strategy in parallel with the modern control method is well excavated in the present paper. Moreover, modulation techniques, variants of reference frames, power quality indices are covered blatantly. Thus, the paper gives fast insight and understanding to the engineers working in this niche area.

“…A 3-phase current signal with a 7 th harmonic component is used in this section in order to analyze the harmonic propagation within the 2DF-IMC control structure. This current is described mathematically by (18) and produces the following d-q signals for a 7 th harmonic SRF (19) If the ac components of the d-q currents in (19) are allowed to propagate in the control loops, then the 2DF-IMC would produce an ac output signal of the type (20) Solving the integral terms in (20) and using the trigonometric identities (21) the following ac expressions are obtained (22) where, using (9) and (10) The fact that the ac output components of the 2DF-IMC are of the type described by (22), where the magnitude and phase displacement is the same for both the d and q components (i.e. and ) means that a single-harmonic input to the  2DF-IMC would produce a single-harmonic output in the modulators when processed by the transformation.…”

“…The disadvantages of PR-based controllers are that attaining adequate controller tuning and stability is a complex process; moreover, the controller resonant frequency should be well tuned to the reference frequency, as the infinite gain band is narrow, making this control technique susceptible to grid frequency variations [9]. Non-ideal PR-based controllers use second order generalized integrators, which results in wider resonant band but with the penalty of an increased tracking error [10].…”

This paper presents a fast selective harmonic current mitigation strategy for inverters with active power filter capabilities based in synchronous reference frames and two-degrees-of-freedom internal model controllers. The advantage of this control strategy over the conventional PI solution is a significant increase in the speed of harmonic detection and mitigation. Furthermore, this control strategy reduces the computational burden when applied in a digital controller. These characteristics make this strategy desirable for applications where fast/harmonic detection and mitigation are needed. Mathematical analysis and simulations are presented to corroborate the performance of the proposed controller strategy. Finally, the results of this proposal are verified in a 1kW 3-phase multifunctional inverter with harmonic compensation capabilities up to the 17 th harmonic.

“…The voltage signal is the output of the controller which can come in different types. Well-known controllers that are used for controlling an inverter are hysteresis controller [16], deadbeat (DB) controller [17], finite-control-set modelpredictive control (FCS-MPC) [18], sliding mode control (SMC) [19], proportional-integral (PI) [20] and proportional resonant (PR) controller [21]. Variable switching frequency and high current ripple are the major boundaries with hysteresis control.…”

<span lang="EN-US">Stand-alone low voltage (LV) microgrids supplying small local loads far from the utility grid are becoming an increasingly popular alternative to a total reliance on the centralized utility grid. In most of LV microgrids, three-phase four-wire distribution systems are used to supply both single- and three-phase loads. Unequal distribution of loads can result in voltage unbalance problems. The use of the four-leg inverter is one of the best solutions for providing a neutral current path and compensating unbalanced load conditions in stand-alone LV microgrids. This paper proposes a fast control technique to compensate unbalanced voltage conditions for a four-leg inverter operating in a stand-alone LV microgrid. The suggested technique provides the current controller’s orthogonal component without introducing any additional dynamics or distortions. The major benefits of the recommended per-phase control technique over conventional orthogonal signal generation (OSG) methods are enhanced steady-state and dynamic performances as well as independency to the system parameters. Several simulation results are provided to confirm the superior performance of the suggested methods.</span>
