“…The coming fundamental refernce current sequence on d-frame with acts as zero which are re-transformed into actual three-phase refernce current quantities (I abc *) by engaging inverse transformation process as illustrated in Equation (10) and Equation (11). The reference current signal (I abc *) is compared to actual line currents for generation of optimal signal to provide the optimal switching states by using pulsewidth modulation technique to regulate the PQ features and DG operation, this proposed controller doesn't requires any additional control objectives to control the DG power while exchanging active/reactive power from distributed generation.…”

“…Effective control scheme generates the optimal switching signals, to achieve the definite compensation task which performs the proper functioning of the proposed MF-DSTATCOM [7], [8]. Various control schemes are reviewed by several literatures, such as symmetrical power theory [9], synchronous reference frame theory [10], instantaneous real power theory [11], etc. The traditional control schemes provides switching signals to DSTATCOM at very high switching frequencies, which makes high switching stress, increased losses and minimizing the over-all compensation efficiency.…”

Distribution Generation plays a significant role in remote areas where the utility grid is affected and initializing by renewable energy sources to acquire the sufficient power demand. In distribution system, it is very exigent consumer related concern which is confronted due to mis-operation of massive non-linear load apparatus. A multi-functional distributed static compensator incorporates the best choice for enhancing the power quality features with effective control scheme under rambled non-linear loads. Conventional control schemes are more adversed with greater switching losses due to extreme harmonic frequencies in a refernce current component. This paper proposes, a novel multi-objective fundamental reference current control scheme based multi-functional DSTATCOM furnishes the current harmonic compensation at PCC, reactive power compensation, power factor correction, active power exchanging, minimizing the switching losses, incredible efficiency and power factor correction. The validation of proposed multi-functional DSTATCOM with proposed control strategy under rated capacity of distribution generation is evaluated by using Matlab/Simulink platform and simulation results are presented.

“…The estimation of ac voltage parameters, such as voltage amplitude and phase angle, will act as a crucial role in the overall performance of the synchronization algorithm. With a low pass filter used to eliminate the harmonics, a synchronous reference frame phase locked loop (SRF-PLL) [21][22][23] as shown in Fig. 5 is used in the proposed control strategy.…”

This paper proposes a novel approach to compensate buses voltage and current harmonics through distributed generation (DG) interfacing converter in a multibus microgrid. The control approach of each individual DG unit was designed to use only feedback variables of the converter itself that can be measured locally. In the proposed approach, the adjacent bus voltage is indirectly derived from the measured DG converter output voltage, DG line current and line impedance. A voltage closed-loop controller and a current closed-loop controller are designed to achieve both functions of DG real power generation and harmonics compensation. Therefore, the traditional harmonic measurement devices installed at the bus as well as the long distance communication between the bus and the DG converter are not required. The proposed approach can compensate the current harmonics, mitigate the buses voltage distortion and enable the customer devices to be operated in normal conditions within the multi-bus microgrid, and meanwhile relieve the burden of power quality regulator installed at the point of common coupling. Matlab simulations and experimental results are presented to show the operational effectiveness of the proposed approach.

“…As a result of this non-sinusoidal voltage drop occurs across the various network elements connected to the system resulting in distorted waveform propagation throughout the system [6].To solve the current and voltage harmonics related problems, the Unified Power Quality Conditioner (UPQC) is one such modern device used for mitigating the effect of voltage and current related problems [4].Unified Power Quality Conditioner (UPQC) is a combination of both series and shunt active power filters which compensate the distortions of both source voltages and load currents [7]. It is used for harmonic elimination and simultaneous compensation of voltage and current, and hence improves the power quality offered by the harmonic sensitive loads [5].…”

In recent years, there is tremendous growth in the use of power electronic devices in every sphere but in nonlinear loads, it has problem of drawing the two important limitations; draws the non-sinusoidal current and reactive power from source which in turn effects the power quality. This paper presents the performance evaluation of unified power quality conditioner (UPQC) for current and voltage harmonic elimination and improved power factor. The combined operation of shunt active power filter and series active power filter ensures THD of source current and load voltage within the permissible limits set by various regulatory agencies and near unity supply power factor. The effectiveness of the UPQC has been verified by the extensive simulation results carried out in MATLAB/Simulink and SimPowerSystem software. The results have been obtained with PI Controller and Fuzzy Logic Controller and then compared.
