This paper deals with the application of three-dimensional fuzzy logic to DC voltage regulation in active power filters exploration, the benefits of this approach, and examples of its application on power quality improvement of PV smart grid system installation. APF are important components of power systems that are used to minimize harmonic distortion and improve power quality. DC voltage regulation is a critical component of active power filters, and traditional control systems have limitations in their ability to account for complex and nuanced conditions, leading to less accurate control and less efficient use of resources. Three-dimensional fuzzy logic is an advanced approach to control systems that allows for more precise and nuanced evaluations of conditions, compering to classical fuzzy logic or the type 2, leading to more accurate control and more efficient use of resources, Three-dimensional fuzzy logic algorithm will be proposed and programed under MATLAB Simulink to control the APF and simulation results are represented and analysed.

Given the growing emphasis on environmental consciousness, there is a spike in the integration of solar photovoltaic energy into contemporary distribution networks. Interestingly, there is a non-linear relationship between the energy production of solar modules and changing external environmental conditions. In response, this study aims to increase the effectiveness of solar photovoltaic systems (SPVS) by putting out a careful analysis to ascertain the ideal performance criteria for the integration of renewable energy sources into distribution networks. The use of a Maximum Power Point Tracker is crucial to this assessment (MPPT). The model provides important insights into the possible increases in energy efficiency, making it a strong tool in this optimization process. In addition, the research conducts a comparison analysis, examining the distribution system properties in relation to different levels of solar PV system penetration. This aspect of the research illuminates the consequences of harmonic-induced distortions in current and voltage on the feeder networks in the distribution system. The simulation findings clearly show that as the penetration capacity of the PV system increases, so does the amount of harmonic dispersion that is introduced into the network. This suggests that it would be wise to incorporate the photovoltaic (PV) array only as far as the network can support it in order to prevent any possible performance reduction. Using MATLAB/SIMULINK as a computational tool, the research carefully examines the important characteristics from the technical data in order to examine the overall model. Further testing of the model's flexibility and resilience under a range of weather scenarios and partial shade conditions offers a thorough assessment of the model's performance dynamics. Positively, the investigation concluded with results that were satisfactory and confirmed the system's exceptional performance capabilities, which are supported by the MPPT. This result reflects a positive trend toward maximizing the integration of renewable energy sources into distribution networks, which will help to create a more sustainable and environmentally friendly energy landscape.

A novel control strategy for a single grid-connected PV system with power backup in different modes of operation, including constant load, changing atmospheric circumstances, and load variable conditions. The proposed controller works with a large nonlinear load under different modes of operation. The controller operates in such a way that, it can achieve different functions such as maintaining power flow between the photovoltaic (PV) module to the grid, maintaining UPF (unity power factor) at the point of common coupling(reactive power compensation), synchronizing a grid with PV (grid current harmonics compensation) and regulates the operation of battery(charging or discharging) for electric vehicle application. Implementing the proposed controller reduces the complexity of the active shunt filter at the point of common coupling (PCC). A maximum Power Point (MPPT) controller, optimized with perturb & observe (P&O)algorithm is used to get optimum power from the PV module. Thesimulation findings validate the operation of the suggested controlstrategy in a grid-connected PV system with a battery backup topology.
