“…Some ways how to improve power quality, especially the THD is presented in [12][13][14]. Usage of DSTATCOM (Distribution STATic COMpensator) for improvement of the power quality indicators is presented in [12] and in [13]. In [14], study on a scheme to reduce the current harmonics from a PV power plant using power conditioner unit placed parallel with the power plant and works in feed-forward mode, and behaves to compensate the PV power plant's output current distortion is presented.…”

Here, the impacts of biogas power plants and photovoltaic (PV) power plants on the power quality in the distribution network are presented and analysed. The biogas power plant's influence on the current harmonics is explored, as a synchronous generator powers the biogas power plant, and the PV plants are connected to the distribution network via the inverter. All the analyses are based on actual measurements that are performed in the last 10 years. Results of the analysis of these numerous measurements were a challenge for investigation how large share of PV systems in distribution network with non-linear loads influence on THD from one side and how biogas power plant with a synchronous generator can improve THD from the other side. In order to investigate interaction of the biomass power plant and PV power plants on the power quality in distribution network, computer model was developed in DIgSILENT Power Factory where PV power plant and household were modelled as a source of current harmonic injections and biomass power plant was modelled as synchronous machine, as a source of voltage harmonics. Analysis of harmonic behaviour in different scenarios is examined through the performed simulations.

“…Hence, integration of solar PV as a DG must have efficient and coordinated control measures for the proper synchronisation. Numerous control algorithms are widely reported in the literature for grid integration of solar PV systems with active power feeding, reactive power compensation and harmonics elimination abilities [4][5][6][7][8][9][10][11][12][13][14][15]. These techniques can be broadly divided in three categories: as conventional, intelligent and adaptive techniques.…”

Integration of solar PV as a distributed generator (DG) require efficient and coordinated control measures for the proper synchronization. In this paper, a hybrid control algorithm for single stage solar photovoltaic (PV) system integrated with low voltage (LV)/medium voltage (MV) grid is proposed. The hybrid algorithm utilizes I cos ϕ technique and quasi-Newton backpropagation (QNBP) neural network (NN). The main contributions of the present work are: i) support the utility grid by feeding power and connected loads, ii) provide harmonics elimination, reactive power compensation, load balancing, iii) also works in power factor correction (PFC) and zero voltage regulation modes, iv) provides power quality improvement. The proposed control of grid tied PV system provides very fast response during static and dynamic conditions. The obtained results are compared with other well-established algorithms available in the literature. The comparison of the proposed algorithm is done on the basis of various parameters such as DC voltage undershoot and overshoot, settling time and THD in grid currents. The developed system is demonstrated in MATLAB/SIMULINK platform. Using the proposed algorithms there is significant improvement of 1.1% in total harmonic distortion (THD) of source current. The results of proposed controllers are experimentally validated on a developed laboratory protype.

“…Basically three categories of custom power devices exist, which can be categories on their respective functionality. For the mitigation of current quality problems a shunt connected device called Distributed Static Synchronous Compensator (D-STATCOM) [5][6] is used. Whereas a series connected device namely DVR [8][9] is used for the rectification of voltage quality problems.…”

For shielding voltage sensitive loads from diverse power quality problems (Voltage harmonic distortion and voltage sag/swell) a wide variety of custom power devices are used. Dynamic voltage restorer (DVR) is one of the important custom power device presently used for mitigation of above mentioned power quality problems. In this paper, reduced-rule fuzzy logic controller based on synchronous reference frame theory for controlling of self-supported dynamic voltage restorer (DVR) is proposed. As a result of the proposed controller, the mathematical model of plant is not at all needed and the control signals required by the DVR are thoroughly provided during various types of power quality problems at the source side. The performance of this technique is better than the other existing techniques and it is very simple to implement, less complex, very flexible and robust in nature. For the same system parameters, the fuzzy logic based controller uses the less amount of reactive power to mitigate the various disturbances at source side compared to PI based controller, which results into reduced rating of IGBTs and consequently leading to lowering of the overall cost. DVR is simulated for mitigation of various power quality problems (voltage harmonic distortion, balanced voltage sag/swell, unbalanced voltage sag/swell, balanced voltage sag/swell with harmonic distortion and unbalanced voltage sag/swell with harmonic distortion) and the simulation results verified by experimental results are presented displaying the workability of proposed controller.
