The growing number of battery technologies and increasing environmental concerns have accelerated the transition to electric vehicles. As internal combustion engine vehicles are replaced by EVs, the impact of EV charging loads on power system operations has become a significant concern. However, the growing adoption of electric vehicles (EVs) presents a challenge for power grids that cannot be neglected. The high charging loads, particularly from
Most medium voltage (MV) distribution systems are structured in mesh and radially operated to distribute electric power from distribution substations to consumers (distribution transformers). The difficult decision of building a new radial MV topology is which branch should be connected to others and could save cost in constructing for the operator in the first stage of designing and bidding for the new topology. Due to that problem which always
The widespread adoption of Electric vehicles (EVs) is largely attributed to their eco-friendly and cost-effective attributes. As the number of EVs charging on electrical distribution systems is expected to rise, it is essential to consider the potential effects on the infrastructure, including generation capacity, transformer overloading levels, line congestion, and load profiles, with the impact of EV charging on load profiles being the most pre
The growing yearly power demand caused by population increases and economic upswings results in considerable energy losses and voltage instability in the distribution system. This study proposes integrating photovoltaic distributed generation (PV-DG) with the battery system (BS) into the grid to address these issues. Despite the many benefits of PV-DG and BS, improper placement can negatively impact the distribution network's technological aspect
When a line, transformer, or feeder blackout occurred in the power system, service restoration was managed to optimal radial topology to restore maximum out-of-service loads with less switch operation and return the system to a healthy operation. This paper presents a new improved sequential opening branch (ISOB) algorithm to propose a solution for service restoration in power distribution systems by considering On-Load Tap Changer (OLTC) and Cap
In this paper, an adjoint sensitivity analysis with an iterative first-order gradient descent optimization technique is proposed in conjunction with the finite-difference time-domain (FDTD) method to design a broadband multi-layer planar electromagnetic wave absorber made of expanded polystyrene mixed with graphite powder. This analysis needs an additional adjoint field simulation for the sensitivity calculation of design parameters (thickness an
Rural electrification is a critical challenge in many developing countries, where conventional grid extension is often not feasible or cost-effective due to low load density and long distances. Hybrid AC/DC microgrids offer a promising alternative solution, providing a reliable and sustainable electricity supply to rural communities. This study presents a comparative analysis of four clustering techniques (hierarchical, k-means, fuzzy c-means, an
Distributed photovoltaic (PV) and battery energy storage (BES) generating systems are interesting to power utilities owing to their benefits in terms of technology, business, and the environment. However, improper distributed generation (DG) sizes and locations might have an impact on the technological distribution network. The aim of this study is to improve the production of grid-connected PV on the electrical three-phase poles of a low-voltage
In recent years, the CubeSat project has become a useful tool to teach university students about space engineering. Getting started with the CubeSat is still a barrier to educational institutions that are new to space technology. Having a satellite training kit to teach students about satellite is an effective approach. This paper provides a design process of the Electrical Power Subsystem (EPS) of the educational satellite training tool in the f
The Internet of Things is considered as the next big technology revolution after the invention of the Internet. Data of IoT are very useful and could produce such huge creativity for us to build many useful applications in our daily life. In Cambodia, the IoT is still a new technology for research and development. However, Security and Privacy are the main key issues for IoT and they are still facing some enormous challenges such as DDoS Attack o
