Power inverters play a crucial role in photovoltaic system (PVs) applications. Transformer less inverters pose several advantages over transformer-based PV inverters, including decreased size, minimal cost, and better efficiency by eliminating the need for a transformer. However, a major drawback is the leakage current which is caused due to the absence of galvanic isolation between the PV panels and grid. This research presents performance analysis of H4, H5, H6 and Improved H6 inverters simulated in MATLAB/SIMULINK software to minimize the leakage current. © 2025 IEEE.

It is known that the wireless power transfer systems are characterized by high order and high nonlinearity. Traditional modeling methods require circuit element parameters to be known a priori or can be accurately measured, but in practical industrial applications, the measured value of the component parameters may be inaccurate, owing to the aging effect of circuit components, changes in coil position, or changes in load impedance. In view of the above problems, based on the input and output data of the system, this paper uses Gauss-Newton method to identify the equivalent dynamic model of the WPT system, which reduces the computational load and burden of model simulation by simplifying the system model, which is more suitable for low-cost applications. © 2023 IEEE.

To further improve the intelligence level of mobile video image applications in power grid scenarios by analyzing the existing problems in the video acquisition system under the current power grid inspection business model, the four aspects of intelligent construction, intelligent equipment, intelligent operation, and intelligent inspection under the new power system technology framework are analyzed. The large business segment is the main line, sorting out the application scenario requirements of multiple power grid security inspections on intelligent image analysis and analyzing the technical advantages of cloud-edge collaboration in the power grid inspection business and intelligent application of video images. With the integration of modern technologies like 5G networks, artificial intelligence, and edge computing, the deployment of power grid video image applications is becoming more efficient. To cater to the management of State grid headquarters, East China branch, and provincial companies, a cloud-edge collaborative deployment mode has been proposed. This model includes a specific deployment architecture design and logical architecture design, which have been explained in detail. The technical architecture of the cloud-edge collaboration model has been discussed from multiple dimensions, including resource collaboration capability, system collaboration security, application collaboration service, business management collaboration, and regional edge collaboration. The purpose of this model is to provide intelligent analysis and optimization management for power grid video inspection applications. Finally, experimental results show that the proposed OPA algorithm can reduce the total cost by up to 60% and has the lowest total cost when the arrival density of computing tasks decreases. © 2023 IEEE.

Distributed Energy Resources Based EV Charging Station With Seamless Connection to grid

IEEE TRANSACTIONS ON INDUSTRY applications 2023年第3期59卷 3826-3836页

The charging of electric vehicles (EVs) via common DC bus charging infrastructure based on hybrid renewable energy sources such as solar photovoltaic (PV) and fuel cell is presented here. The requisite to incorporate renewable energy based distributed energy resources (DERs) is attributed to the escalating concern for decarbonisation with improved power quality requirements. Furthermore, the bidirectional flow of power enables the charging/discharging of EVs during the grid presence/absence modes of operation. In addition, the utilization of common DC bus charging mechanism for EVs, facilitates fast charging capability at higher voltage levels. The satisfactory operation during the grid availability/unavailability is attained through the current and voltage based control mechanisms, along with the seamless transition capability via switching (STS-1/0) of the static transfer switches. Furthermore, in compliance with the IEEE standards, the power quality (PQ) improvement is obtained with the utilization of an adaptive comb-filter based current control during the grid-tied mode of operation. The need for improving PQ, stems from the fact that an uninterrupted supply is essential to the critical loads along with an improved power quality. Thus, for validation and corroboration of the system behavior, its performance is authenticated during weak grid conditions, in conjunction with grid connected/islanded modes of operation.

Assumable Logic Programming (ALP), an extension of Answer Set Programming (ASP), has been theoretically demonstrated to possess significant advantages in addressing problems involving incomplete information. Therefore, the development of ALP solvers is urgently needed to facilitate further research and applications. This paper proposes a solving algorithm named Answer Set Based View Search (ASBVS) and its optimization to compute the results of ALP programs. Based on this, the ALPSolver has been implemented and integrated into an online platform for public use. This paper experimentally validates the correctness of the solving algorithm and confirms the advantages of ALP in handling default information, indirect exception and abductive reasoning. Additionally, the experimental results demonstrate the effectiveness of the optimization algorithm, with a notable increase in efficiency as the problem scale increases. © 2024 IEEE.

GIRAFF: Reverse Auction-based Placement for Fog Functions

9th international Workshop on Serverless computing (WoSC) Part of Middleware conference

Function-as-a-Service (FaaS) is a compelling new programming model for developing applications running on fog infrastructures. FaaS applications are composed of short-lived, event-triggered units, called functions. Functions can be flexibly deployed on demand along the cloud-to-thing continuum. However, deciding how to place those functions in the fog presents multiple challenges. The fog contains diverse, geo-distributed, and potentially resource-constrained nodes that should be efficiently shared between applications with latency requirements. Importantly, fog nodes are owned by different entities that should be incentivized to share their resources. Most function placement approaches ignore latency requirements or the presence of multiple owners in fog infrastructures. To address these challenges, this article proposes a market-based approach to place FaaS applications in the fog. Clients submit function placement requests associated with SLAs that specify expected guarantees over network latency and allocated resources. The approach then organizes an auction among fog node providers to determine the nodes that host each function and the revenue of the provider. The article presents an open-source implementation of the approach evaluated on the grid'5000 testbed. Experiments demonstrate that our approach can reduce client spending by up to three times while delivering service quality that matches or exceeds that of baseline methods.

The paper presents a new common ground single-phase transformerless five-level inverter for Photovoltaic (PV) applications. The topology is built with a minimum of six switches and three capacitors compared to various five-level inverter proposed in the literature and has the advantage of 100% dc-link utilization. The topology has the capability to supply both real power and reactive power. In order to achieve this, a simple level-shifted pulse width modulation scheme is used and proportional-resonant (PR) controller is developed to study the dynamic response of the system under input voltage as well as grid current changes. The performance of the proposed topology and their control scheme is validated through MATLAB simulation results. Finally, a detailed comparison is made with the recent five-level inverter topologies to highlight the merits of the proposed topolozy. © 2024 IEEE.
