To address the problem of low accuracy of insulator defect detection in complex environments, this paper proposes an improved YOLOv5s-based insulator defect detection algorithm. First, the K-means algorithm is used to cluster the data set to obtain the best anchor frame size, which effectively improves the generalization ability and localization accuracy of the model; second, the Backbone part of YOLOv5s is embedded with the Coordinate Attention module to improve the feature extraction ability of the network to solve the influence of invalid features on the recognition accuracy; finally, the EIOU-Loss is used to improve the accuracy of insulator defect detection. Finally, the performance of the model is optimized using the EIOU-Loss function, and ablation experiments are set up to validate the proposed method. The experimental results show that the Precious and mAP of the improved YOLOv5s model are improved by2.S% and 1.6%, respectively, compared with the original YOLOv5s network.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116812992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The DC microgrid consist of a Photovoltaic Power System, a BSS to enhance the generation of power in the inability of a PV system, and a DC shunt motor connected as dynamic load. Battery storage system (BSS) helps to stabilize the system against the instability caused by stochastic nature of the renewable sources as well as demand variation within a microgrid To extract the maximum power from the PV array, we will implement a maximum power point tracking system (MPPTs). The BSS feeds the load through a bidirectional DC-DC buck-boost converter. The BSS is put into operation when the MG is in an emergency where the battery can provide backup when the PV system fails to generate the demand load under different weather conditions.

Unlike conventional vehicles, EVs have an electric power circuit composed of power electronic converters that together make up the battery charging system and the powertrain. These systems usually have different voltage levels, so it is attractive to use isolated converters, for example, the Dual Active Bridge (DAB) converter. Among the various techniques used to control converters, the application of model predictive control (MPC) has recently become evident. The advantages of predictive control are the design based on plant equations, the ease of implementation, and good precision and accuracy. In MPC the search for the desired setpoint is performed by minimizing a cost function. In the present study, the minimization of the cost function is achieved using the gradient descent technique. Also, computer simulations performed on the Matlab/Simulink platform with the DAB converter being controlled by MPC and MPC with gradient descent are presented and the results compared and discussed.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"329 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123396823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this work is a technical analysis for the transformation of the Milan-Lecco (S7) line located in a region of northern Italy currently with diesel traction. In particular, the section of 29.2 km between Monza and Molteno stations is analyzed. In this section, the solution of using battery-powered trains while avoiding the construction of catenary is evaluated. Within the case study, the vehicle type (train) is identified, the battery is sized, and a driving control analysis is performed.

A dynamic probabilistic method has been proposed to calculate the hourly total frequency control reserve, which is the total of the secondary and tertiary reserve requirements. In this work, historical operations data of the Visayas grid were used to determine the relative contributions of load and VRE errors to the reserve requirements and to explore the effect of varying the reliability target on the frequency control reserve requirement.
