Recent work on developing a framework to predict remaining useful life (RUL) has primarily focused on the traditional empirical degradation model due to its simplicity. Although this model works well under specific operational conditions, for online RUL prediction it may lack the ability to describe capacity degradation, given the variability in decline between cells and others under different operational conditions. As such, this can result in inaccurate RUL prediction. Therefore, this work proposes a hybrid approach to improve the accuracy of online forecasting in the existing framework by integrating data-driven and model-based approaches. The proposed framework utilises the neural network (NN) to model and track battery degradation trends, and it also degrades the initial values of the degradation model’s transactions under different operating conditions. Furthermore, the proposed hybrid framework includes smooth particle filter (SPF) algorithm, which continuously updates the degradation NN model. Lithium-ion battery capacity degradation datasets from the Centre for Advanced Life Cycle Engineering (CALCE) were used to evaluate the proposed paradigm. The results show that the proposed hybrid framework is more accurate and improves the convergence rate compared to the traditional capacity prognostic framework","PeriodicalId":371561,"journal":{"name":"2022 57th International Universities Power Engineering Conference (UPEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123588760","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}

In a typical application the over voltage relay is used for over voltage protection, which is connected to a potential transformer, and calibrated to operate at or above a specific voltage level. An “Under Voltage Relay” and an “Over Current Relay” are also protective relays which operate when the voltage is reduced, or the current is increased below or above a preset value. In a typical application these relays are connected to potential transformers, and calibrated to operate at, above or below a specific voltage or current levels. The emulator used in paper simulated experiments of all three types of relays mentioned above. The transmission line emulator used in this paper is an HVAC transmission line of length of 180 km. The transmission line of the emulator can be used as a 3-phase transmission line of 180 km length or as a single-phase transmission line of 540 km long. This transmission line in the emulator is divided into 6 $pi$ sections and each $pi$ section is 30 km long. The line inductance of the transmission line of the emulator is examined for every 30 km and the line capacitance is examined for every 15 km.

Among other reasons, the integration of renewable energy sources (RES) and increasing electromobility make safe and reliable grid operation in conventional structures more difficult. More monitoring devices are increasingly being installed to better track grid conditions and make them available for analysis functions. A powerful grid automation system is becoming a key factor in the operation of distribution grids. Novel automation functions as well as decision support capabilities are required to cope with adverse network conditions and the massive amount of data. Complementing classical monitoring systems, this paper shows an approach and use cases of a real-time simulation (RT) parallel to the grid based on measured data, system identification and state estimation of the real grid. The system extends the monitoring functionalities to an influence reactive system that can reproduce the network operation in a realistic environment. As with hardware-in-the-loop (HiL) simulations, this approach provides a platform for testing and monitoring the automation functions of distribution networks.","PeriodicalId":371561,"journal":{"name":"2022 57th International Universities Power Engineering Conference (UPEC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133207005","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}
