However, the distributed control schemes bring significant challenges to the system operation due to their high dependency on data transmission through communication networks, making them vulnerable to cyber-attacks. Because of their wide range of applications, cyber-attack detection in DCMGs has recently gained considerable attention. In most machine learning (ML)-based cyber-attack detection algorithms, accurate real-time output estimation with a low computation burden is critical. In this paper, an Adaptive Neuro-Fuzzy Inference Systems (ANFIS)-based real-time estimator is proposed for DCMGs. The proposed technique is used in a cyber-attack detection and mitigation framework to estimate output voltage and current for DC/DC converters with acceptable accuracy and computational cost. Cyber-attack detection has been achieved through residual analysis, comparing the estimated and measured data. Finally, the effectiveness of the proposed ANFIS-based real-time estimator for the ML-based cyberattack detection frameworks is validated in a MATLAB/Simulink testbed and compared to other supervised ML algorithms.","PeriodicalId":210548,"journal":{"name":"2023 23rd International Scientific Conference on Electric Power Engineering (EPE)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126089699","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}

This paper presents design of 10 MWp PV power plant for Kikuletwa Renewable Energy Center located at Kilimanjaro region in Tanzania. Results from the designed PV plant and distribution network data are applied to perform detailed grid interconnection studies in order to evaluate technical performance of the plant as per standards and the current national grid code in Tanzania. The PV plant and existing Medium voltage distribution network are modelled in Electrical Transient Analysis Program (ETAP) software. Then, load flow, short circuit, power quality and stability analysis studies are performed. Results of the studies are applied to evaluate technical feasibility of interconnecting the designed 10 MW PV plant to the distribution network. The study demonstrate relationship between sizing of large scale PV power plant and grid interconnection studies. It is confirmed that load flow, bus voltages, short circuit currents and transient stability of the system are within the required national grid code and standards limits. Interconnection of PV power plant has enabled injection of 4.38 MW into the main grid and improvement of voltage profile of several feeders in the distribution network by 2%-4%. It is recommended to install harmonic filter at PV power plant substation bus bar in order to reduce the Total Harmonic Distortion (THD) to less than or equal to 5% as required by standards.","PeriodicalId":210548,"journal":{"name":"2023 23rd International Scientific Conference on Electric Power Engineering (EPE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125258651","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 power systems and especially transmission lines were designed for expected weather conditions and the rapid change in weather is putting a real strain on the transmission line grid. The transmission lines have not changed fundamentally in the last 100 years, and they have not been considered when it comes to advancements in technology over the last few decades. There are no common practices in monitoring transmission lines, but recent advancement has finally made real time monitoring a financially reasonable decision. This paper will review different extreme weather events and how they can affect transmission lines and how the real time monitoring of these effects could be utilized for smart grid applications in transmission grids.","PeriodicalId":210548,"journal":{"name":"2023 23rd International Scientific Conference on Electric Power Engineering (EPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115695169","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}

Before the measurement, it is necessary to calibrate the entire circuit using a calibrator that generates an accurate charge value. There are now emerging requirements to increase the verification accuracy of these calibrators for charge values less than a few pC. In this paper, a comparison is made between two possible calibration procedures, namely the numerical integration method and the procedure using special charge-sensitive amplifiers. The comparison is made based on uncertainty analysis and practical laboratory measurements. The results show that the use of charge-sensitive amplifiers brings a significant reduction of the calibration uncertainty in the small charge region.","PeriodicalId":210548,"journal":{"name":"2023 23rd International Scientific Conference on Electric Power Engineering (EPE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125229031","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}

Independent of the operation state, the machine’s operation can accurately be described with fundamental mathematical approaches. In a big contrast, such mathematical formulations are not suitable for converter-based generation units. In dependency of applied converter control strategies, hardware and control algorithms, the converter’s operational behavior can vary on a broad spectrum. In order to incorporate renewable energy sources (RES) like wind or photovoltaic into the electric power grid, converters are necessary. Therefore, the integration of RES into the electric grid leads to large-scale operational changes for grid operators. Changes in the electric power grid can especially be observed while considering system inertia or stability, short circuit characteristics and power system protection.","PeriodicalId":210548,"journal":{"name":"2023 23rd International Scientific Conference on Electric Power Engineering (EPE)","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114851984","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}
