Renewable energy resources are highly dynamic and somewhat intermittent compared to more traditional generation sources. Hence, they pose a challenge to the electrical network operator in terms of effectively managing their resources to maximize energy transfer while maintaining a stable interconnected network. Further, there is an increasing percentage of electrical energy generation that is connected at the utilization end of the electrical power network which poses challenges for energy flow, voltage stability and protection systems. This paper will initially discuss the concept of a grid forming system that forms the reference point of future embedded electrical power systems. The role that grid forming converters could have in future very weak system is discussed A traditional synchronous compensator forms part of the grid forming system and provides some limited energy input during energy transients, some reactive VAr capability, but importantly, high transient fault currents, which will strengthen the system and help it maintain stability.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116198385","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 particular, the issue of the intermittence in power generation of renewable energy sources make it necessary their implementation in such plants. It is very important to take into account the aging phenomena of LIBs to optimize their usage and extend their lifetime. The aging is usually decomposed into calendar aging and cycle aging. In general, the factors that affect it are the temperature, the state of charge, the voltage limits, and the current rate. Several works analysed also the effect of the current ripple on the battery aging. Nevertheless, a rigorous analysis of the effect of the current frequency seems to be missing. Indeed, almost all the aging analyses relating current ripple do not take into account the higher temperatures due to the current ripple losses. Therefore, the effects of increased temperature and current ripple are never separated. Moreover, different frequency components in the same current ripple may lead to different aging. In this paper, a method to separate the temperature by the current frequency effect is proposed and the analysis of the aging LIBs due to the 100 Hz current harmonic is carried out.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129026606","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}

Using batteries for this purpose in grid-level systems are highly recommended due to the flexibility in installation, modularization and fast response. Comparing to the other types, Lithium-ion batteries (LIBs) are a more common choice in industry because of their higher energy efficiency and density, inexpensive manufacturing cost and long life cycle. To use the batteries optimally, reliable state of health (SoH) monitoring solutions are required to be included in the battery management system (BMS). This paper proposes a simulation assisted electrode and electrolyte current density monitoring for lithium-ion batteries that can considerably increase the SoH estimation accuracy. The proposed method is realized through the fusion of the information from the magnetic field sensors together with the online simulation of the battery dynamic model, in real-time. The battery model of an electric vehicle is developed in COMSOL modelling software and the data fusion is implemented on dSPACE Microlabbox real-time simulator. The results confirm that the proposed monitoring solution can be potentially used to provide a highly accurate estimation system for a Lithium-ion cell.","PeriodicalId":223615,"journal":{"name":"The 9th Renewable Power Generation Conference (RPG Dublin Online 2021)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127574573","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}
