Remotely sensed imagery by means of Unmanned Aerial Vehicles (UAVs) is actively used in this context as it allows faster, cost-effective and contactless characterization of modules’ surface together with large-scale deployment. We develop herein an end-to-end approach to detect, identify and locate on field defects on PV installations based on RGB imagery acquired by UAVs. The approach is fundamentally designed for large-scale applications and comprises: (1) A photogrammetric image acquisition and post-processing phase that produces one orthorectified and georeferenced support covering the entire inspected site; (2) A module extraction phase that yields the individual images of modules; and (3) A deep learning-based defect detection stage using a fine-tuned instance of the YOLOv4 architecture. The approach was developed, validated and tested using a dataset collected from two large-scale PV sites comprising 35 305 modules. The developed defect detector scored a mean Average Precision (mAP) of 83% and 73% respectively on the validation and test sets.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126872982","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}

Microgrids are an integral part of smart grids playing a prominent role in supplying power to regions lacking electrical infrastructure. Since there may be diverse Distributed Generation (DG) sources in a microgrid, it is challenging to maintain the bus voltage at the desired value, which may adversely affect the performance of microgrids. This demands the implementation of controllers. The classical PID controller would be an apt choice in such a scenario. To obtain the desired output, it is necessary to perform the tuning of control parameters-proportional, integral and derivative gains, Kp, Ki and Kd, respectively. This paper presents the implementation of Grey Wolf Optimizer (GWO) Algorithm tuned PID Controller to maintain the DC link voltage of a microgrid under study. The latter part of the paper presents a multi-microgrid interconnection scheme. The GWO Algorithm has been implemented for the cost optimization of this multi-microgrid interconnection scheme, consisting of thermal units, solar PV array and wind generation. It has been proved that there is considerable savings in the total cost due to the integration of solar PV array and wind generation. The microgrid modeling and simulations in both cases are performed in the MATLAB/Simulink environment.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127622164","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 real-time ampacity of overhead conductors is tremendously fluctuating due to its dependence on weather conditions. As a result, the real-time rating of the overhead conductor is better exploited by using dynamic line rating (DLR) than traditional conservative static rating, which depends on the worst-case weather conditions. Since there are high uncertainties associated with point forecast DLR ampacity calculation, probabilistic means of DLR forecasting method provide the possibility for short-term planning and real-time overhead transmission line ampacity monitoring, thus enabling the transmission network to run smoothly without harm to the entire network. In this study, a real-time DLR overhead transmission line is formulated, giving 24-hour ahead ampacity prediction and loading limits by using quantile regression forest (QRF) machine learning model with different quantiles. The proposed method provides better enhancement and safe operation for the lowest quantiles to mitigate decision-makers risk-averse.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132642690","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}
