Electric arc furnaces used in the smelting process are non-linear loads that consume large amounts of power and change very quickly over time. The characteristics of electric arc furnaces that fluctuate rapidly may cause several problems such as system frequency instability. To compensate the intermittency of an electric arc furnace, a Static Watt Compensator (SWC) or Battery Energy Storage System (BESS) can be used. This paper discusses the comparison between the Static Watt Compensator and Battery Energy Storage System in terms of performance, sizing, and cost. The modeling and the simulation will be carried out with DIgSILENT PowerFactory, a power system analysis software. The performance of SWC and BESS will be compared by using the Integral Square Error (ISE) method. The results show that SWC maintains system frequency by absorbing active power and can only overcome the system's over-frequency condition, whereas BESS maintains system frequency by supplying or absorbing active power so that it can overcome both over-frequency and under-frequency conditions. However, the use of SWC increases system losses, which causes the total cost of SWC slightly higher than BESS.","PeriodicalId":6768,"journal":{"name":"2020 IEEE International Conference on Power and Energy (PECon)","volume":"43 1","pages":"409-414"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74675187","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}

However, the operation of DGs can also lead to complexity in the protection of distribution networks. As a case study, this paper will consider the effects of two DG types on the protection system of DNs through analyzing a proposed Fault Location, Isolation, and Service Restoration (FLISR) approach. This FLISR approach can achieve fast total fault processing time and meanwhile consider DGs as ancillary services for post-fault restoration planning of the DN to minimize the number of outage customers and the amount of lost power. Specifically, tripping-threshold currents of overcurrent relays are combined with the status of switching devices and the loss of voltage to detect and locate different faults in a distribution network with DGs. Isolation of faulted sections and post-fault service restoration in the DN are implemented by solving an objective function with two constraints. Six performance indices are selected for the post-fault SR process. By using E-Terra software for a distribution management system (DMS), simulation results of a 22kV distribution network with DGs are used to validate the proposed FLISR approach. Consequently, the developed FLISR approach could be effectively adaptable to high penetration of DGs into the distribution network and able to properly indicate risks of protection mis-coordination, quickly detect and locate various faults as well as rank all possible post-fault SR plans in DG-integrated distribution networks within a total time of two minutes.","PeriodicalId":6768,"journal":{"name":"2020 IEEE International Conference on Power and Energy (PECon)","volume":"2 1","pages":"125-130"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75005791","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}

Transformer is one of these critical assets and its failure can cause major downtime in the electrical supply and result in the revenue losses to the utilities or plant operator. Over the last decade, condition-based maintenance has been actively engaged as the maintenance regime for the maintenance of in-service power transformer. As such, the basic and advance diagnostic testing has been used to diagnose and assess the condition of the transformers. A large utility typically has in excess of a thousand power transformers and prioritizing the maintenance of the transformer is important to optimize the operational cost and at the same time avoid the unplanned outages.

The change in the resistive leakage current and particularly its third harmonic component is considered as an excellent indication of arrester’s ageing. The presence of third harmonic in the grid’s voltage affects the extraction of third harmonic resistive current. Therefore, it can lead to incorrect condition assessment of MOSA. This paper aims to introduce a new ageing indicator for MOSA, which is independent of voltage harmonics. This analysis is performed experimentally on three aged samples of 120kV rated polymeric MOSAs manufactured by ABB. Fast fourier transform (FFT) is applied to the acquired resistive leakage current to extract its harmonic parameters. It is found that the fifth harmonic resistive current exhibits similar sensitivity towards ageing as compared to the third harmonic resistive current. Results have shown that the condition assessment based on third harmonic current can easily be replaced with the fifth harmonic current.","PeriodicalId":6768,"journal":{"name":"2020 IEEE International Conference on Power and Energy (PECon)","volume":"5 1","pages":"382-385"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81671908","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}
