The concept of solar cell is changing the world in obtaining a clean energy that is an environment user friendly source of energy. Solar arrays process and convert the irradiance which is representing the quantity of light that comes from sun to a usable energy. The maximum power point which is denoted by Maximum power (Pmax) can be efficiently extracted from solar panels through the implementation of a tracking system denoted by the maximum power point tracking algorithm (MPPT). Such a tracking system is well known and utilized in detecting the ultimate maximum power that can be taken from the PV solar arrays under the circumstances of the various changes in both the temperature and irradiance. Through this analysis study, the Perturb and Observe (P&O) algorithm will be proposed to adjust the perturbation steps that will be controlled by an enhanced fuzzy logic controller. It will utilize the fuzzy concepts to extract the maximum power. In this research paper an analysis will be conducted to find the unknown parameters of the PV module along in selecting the appropriate set of fuzzy rules/fuzzy table as well as introducing a high gain dc-dc boost converter to improve the efficiency of power, response time, and reducing the oscillation around the Pmax in the proposed photovoltaic system. © 2025 The Author(s).

The application of high-resolution satellite images in deep learning-based change detection methods has become increasingly popular. However, the down-sampling and cropping strategies deployed to fit the GPU memory constraint often result in incomplete semantic information and loss of fine details. This paper proposes a collaborative network based on feature pyramids, which enables networks to learn local and global features from cropped and down-sampled image patches. A feature-sharing mechanism is also introduced to fuse global features and local features. We evaluated the network on the LEVIR and S2Looking datasets by comparing it with some representative change detection networks. Comparative experiments show that the proposed network performs better in multi-scale change detection, improving precision by 2.69% on the LEVIR-CD dataset, and improving precision and recall by 6.83% and 2.68% on the S2Looking dataset, respectively. © 2025 IEEE.

In this paper, a novel algorithm had been proposed to improve the efficiency performance of the wind energy conversion system (WECS) to reach the maximum possible captured power under fast varying wind speed. The permanent magnet synchronous generator (PMSG) had been selected because of its reliability and efficient performance, especially in low-speed conditions environment. The novel algorithm applied the power prediction mode to make optimization for the reached decision to the maximum peak point. The proposed algorithm shows better efficiency performance for different wind speed conditions. The novel algorithm accelerates convergence to detect the maximum peak point without sacrificing efficiency. The novel algorithm’s simplicity reduces the overall time required by 33% when compared to the three-mode algorithm. © 2025 The Author(s).

In recent years, the power grid in Jiangxi Province has entered a new phase of construction in the context of a new power system. However, the traditional network security protection system of the company is facing increasing security risks [1]. This paper first elucidates the network structure characteristics of the new power system and identifies the security risks it faces. Subsequently, combining the characteristics of boundary protection and static protection in the existing network security protection system, this paper analyzes the challenges faced by the protection system from aspects such as power source structure, grid configuration, business models, and technical foundations. Based on the content of security challenges, the paper proposes the requirements for network security protection in terms of trusted access, intelligent perception, and precise protection. Lastly, in conjunction with the development trends of security systems and new technologies, the paper summarizes the technological development directions in areas such as perception technology, blocking technology, security detection and evaluation technology, and validation technology.

Bi-directional DC-DC converters have many applications in in-vehicle power supplies and microgrids. Bi-directional DAB (dual active bridge) converters are proposed to optimize the charging system for electric vehicles. This paper analyzes a typical Bi-directional DC-DC converter topology whose input and output sides of the converter have simple symmetrical structure. The modes of the converter in different operating phases are analyzed, and a phase shift control system is designed based on TPS5430DR. Finally, design and test of the DC-DC converter are implemented. © 2025 SPIE.

In order to understand the optimization system of hydraulic power generation system based on particle swarm optimization algorithm, the optimization technique of hydraulic power generation system based on particle swarm algorithm has been proposed. The author first analyzes the principle of a piezoelectric power generation system. The advantages of flexible secondary energy conversion in hydraulic systems have made hydraulic power generation technology a hot topic in the current field of new energy power generation. However, the dynamic and pulsating characteristics of hydraulic systems have an important impact on the working performance, accuracy, and stability of the entire power generation system. Second, a dynamic simulation model of the hydraulic system based on AMESim was developed using the hydraulic power generation system as the research object. system pressure pulsation was systematically examined in relation to pump speed, system pressure, and pipeline length, as well as the suppression effect of a dual pump parallel connection on pressure pulsation. The simulation results show that an increase in pump speed and system pressure will exacerbate system pressure pulsation. When the pump speed increases by 10 r/min, the average pressure pulsation rate increases by over 5.17%;When the load pressure increases by 2.5 MPa, the average pressure pulsation rate increases by more than 5.89%;AMESim simulation provides a more accurate and efficient method for comprehensively studying the pulsation characteristics and optimization of hydraulic systems. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

In the last decade, blockchain technology has garnered significant attention for its potential to transform a variety of industries and also power systems. This review aims to provide a detailed view on blockchain technology, features that make it significant, limitations, applications in the power system sector, and further challenges that this technology faces for diving into the energy market. It highlights some features of blockchain technology such as transparency, decentralization, security, and immutability. However, the blockchain technology possesses some inherent limitations that makes their integration into the power system challenging. This paper aims to critically examine these limitations and their consequences for application in the power system, all the while offering some potential solutions to tackle these challenges. While in recent years blockchain technology has seen its application and usage in various domains, experiencing its highs and lows, the power system is the domain that remains largely unexplored. As more and more distributed and renewable energy systems are coming into picture, this article highlights features such as transparency and traceability of blockchain technology. However, a balanced approach needs to be considered and implementation of blockchain should align with real world requirements in the energy market. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
