Abstract

Considering the study of optimal location of distributed units to improve network reliability under network operation conditions and the focus on using the genetic algorithm method for locating distributed generation units in the distribution system, there is no comprehensive and relevant research in this field. In this research, to improve network reliability, location with variable numbers and sizes of distributed generation resources is performed. In the proposed method, multi-objective optimization using weight coefficients to combine two objective functions as the overall objective function is used.

Abstract

Wireless communication systems have seen exponential growth due to the increasing demand for high-speed data transmission, improved spectral efficiency, and enhanced energy optimization. This paper explores optimization techniques for reliable data communication in multi-antenna wireless systems, particularly focusing on Multiple-Input Multiple-Output (MIMO) and Multiple-Input Single-Output (MISO) architectures. The study integrates beamforming, energy harvesting, and secure wireless information transmission through novel mathematical optimization frameworks. Key contributions include coordinated multi-cell beamforming, SINR balancing for energy-harvesting systems, and secrecy wireless information and power transfer (SWIPT) in MIMO channels. Experimental simulations demonstrate significant improvements in signal-to-noise ratio (SNR), power efficiency, and security enhancement, making these methods viable for next-generation 5G and 6G networks.

Abstract

Photovoltaic (PV) power generation systems require effective maximum power point tracking (MPPT) algorithms to ensure optimal energy conversion efficiency. This research presents a novel MPPT algorithm based on the Dividing Rectangles (DIRECT) algorithm, which offers improved tracking performance under rapidly changing insolation and partial shading conditions. Compared to conventional techniques such as Perturb & Observe (P&O) and Incremental Conductance (INC), the proposed method effectively identifies and tracks the global maximum power point (GMPP) while minimizing steady-state oscillations. The effectiveness of the approach is validated through simulation and experimental results, demonstrating enhanced tracking speed and energy efficiency.

Abstract

The emergence of electric vehicles (EVs) signifies a transformative potential for the future of transportation on a global scale. The transition from fuel-dependent transportation to electric-powered systems marks a significant breakthrough in energy efficiency, conservation, and the facilitation of smooth energy transitions. This initiative also aims to reduce harmful emissions that have significant environmental impacts, including influencing weather patterns and contributing to global warming. Advancements in technology have led numerous companies to manufacture electric vehicles (EVs). However, charging remains a significant challenge for EVs. Various methods have been proposed to address this concern, with one conventional approach being the charging of vehicles at designated stations. However, this method is limited by the time required for charging and the restricted travel distances. As a result, wireless charging has been proposed as an alternative solution. Several factors influence the efficacy of wireless charging, with various techniques developed that rely on electromagnetic induction or inductive power transfer. Although passive wireless charging has been implemented, challenges related to the placement of charging pads and stations continue to arise. The parameters influencing these charging methods and the positioning of charging infrastructure are critical to the system’s success. This system operates through affordable inductive coupling between two coils, known as the transmitter and receiver coils. In the context of EV charging, transmitter coils are typically embedded in the roadway, while receiver coils are installed within the vehicle.
