Abstract

A resilient approach is presented in this study for detecting and classifying faults for power distribution systems integrating renewable energy sources (RES). Combining discrete wavelet transform (DWT) and convolutional neural network (CNN). The suggested framework addresses the challenges of RES intermittency and kinetic energy insufficiency. The recommended methodology is evaluated in a MATLAB platform, featuring a power distribution system with photovoltaic (PV) and wind energy conversion system (WECS), stabilized by a boost converter and cascaded fuzzy logic controller (CFLC) based maximum power point tracking (MPPT) for PV and a PI controller for WECS. Comparative analyses demonstrate the superior performance of the CNN classifier with an accuracy of 96.33%, outshining existing classifiers, including ANN. Furthermore, under various fault conditions, the CNN consistently achieves high accuracy, with 98% for Islanding, 95% for line-to-ground fault, and 96% for line-to-line fault. The proposed approach exhibits excellent computational efficiency, with a training time of 10.5 hours, inference speed of 5 milliseconds, and resource utilization of 85%, emphasizing its suitability for instantaneous fault identification in power systems.

Abstract

The energy usage of the electricity system increased dramatically during the last few years as a result of the rise in consumers and businesses. It resulted in large-scale traditional energy generation, causing an increase in global emissions. As a result, the perforation of sources that are renewable inside electrical networks has greatly grown. Solar power systems (PS) have grown into the most prominent sources because of their tremendous potential; hence, global installed solar power capability has expanded beyond more than 635 gigawatts (GW), representing about 2% of the world’s energy consumption. Multilevel inverters (MLI) are now on top of two-level inverters due to their ability to deliver diminished electromagnetic interference (EMI) and elevated capability. This study examines MLIs in terms of categorization, development, and problems, as well as practical advice for use in renewable energy systems (RES). This review also emphasizes the significance and development of an improved multilevel inverter. In summary, this study focuses on the usage of multilayer inverters in PV systems to stimulate and assist society in developing efficient, cost-effective inverters with integrated capacities of those converters described in the survey.
