“…Nevertheless, unlike conventional generation units, high-capacity PV units, like in the range of multi MW, will have a huge effect on the dynamic performance of the interconnected power system and also will have an important impact on the reliable and stable operation of interconnected systems [9,10]. Thus, in the view of the assessment of the grid-connected operation characteristics of the grid scale PV systems, researchers have carried out a vast number of modeling and control studies on dynamic impact and PV system and their contribution on grid support and ancillary services [11,12].…”

This paper reports a general overview of current research on analysis and control of the power grid with grid scale PV-based power generations as well as of various consequences of grid scale integration of PV generation units into the power systems. Moreover, the history of PV renewable growth, deregulation of power system and issues related to grid-connected PV systems considering its contribution to various responsibilities like frequency control, virtual inertia capabilities and voltage regulation are discussed. Moreover, various outcomes of the high-penetrated grid with PV power plants such as power quality, active and reactive power control, protection, balancing and reliability under various loading conditions are reviewed and discussed.

“…Equivalent modeling of PV power plant is to simplify the detailed model of PV power plant with multiple PV units into the equivalent model of PV power plant with only one or a few PV units [8]. The dynamic response characteristics of point of common coupling (PCC) are consistent before and after equivalent modeling.…”

The equivalent model of photovoltaic (PV) power plant can greatly improve the model simulation speed on the basis of satisfying the simulation accuracy. However, in equivalent modeling of PV power plant, there are strong correlations and subjectivity between the selected initial variables, which will cause inaccurate equivalent results. Therefore, this paper proposes an equivalent modeling method of PV power plant based on factor analysis and correlation clustering. First, the factor analysis is used to reduce the dimensions of initial variables to eliminate the correlations between clustering indexes. The factor rotation and factor scores are adapted to mine the actual physical meaning of data, extracting the operation states of PV units, and eliminating the subjectivity of clustering indexes. Second, the correlation analysis and significance test are applied to analyze the extracted operation state indexes to obtain the correlations between PV units for clustering. Third, by the contour visualization, the correlations between PV units are qualitatively analyzed and the rationality of clustering results is judged. Finally, the equivalent parameters are calculated based on clustering results to establish the equivalent model of the PV power plant. The simulation results show that the proposed equivalent modeling method not only improves the simulation speed but also fit the simulation accuracy as well. The adaptability of the equivalent modeling method under different working conditions is also verified. The established equivalent model can be used to analyze the interaction between the PV power plant and power grid as well as the power system analysis with large-scale new energy, which is practical and popularized. INDEX TERMS Correlation clustering, contour visualization, equivalent modeling, factor analysis, PV power plant.

The power generation of the world has to be increased every year as the demand increases rapidly. The high power generations are done by hydro, thermal and atomic. The power production cant is increased every year as the cost of power production increases due to this constraint and increase in high power generation increases pollutions. So the distribution side generation are used, and the PV based power generations are used mostly as the maintenance is less comparatively. The power control in PV power generation is done by DQ technique which is most widely used. It has a PI controller to regulate the real power.In this paper, the fuzzy logic control which is combined with the PI controller is used to increase the controllability of the power system. The MATLAB 2017b is used to do the simulation of the applied technique and the results are discussed with improvements.
