However, poor useful life and relatively high cost of batteries result in barriers that hinder the wider adoption of battery technologies e.g., renewable resources storage. Furthermore, the useful life of a battery is significantly affected by the materials composition, system design and operating conditions, hence, made the control and management of battery systems more challenging. Digitalisation and artificial intelligence (AI) offer an opportunity to establish a battery digital twin that has great potentials to improve the situational awareness of battery management systems and enable the optimal operation of battery storage units. An accurate estimation of the state of charge (SOC) can indicate the battery's status, provide valuable information for maintenance and maximise its useful life. In this paper, a digital twin-driven framework based on a hybrid model that connects LSTM (long short-term memory) and EKF (extended Kalman filter) has been proposed to estimate the SOC of a li-ion battery. LSTM provides more accurate initial SOC estimations and impedance model data to EKF. According to experimental results, the developed battery digital twin is considered less dependent on the initial SOC conditions and is deemed more robust compared to traditional means with a lower RMSE (root mean squared error).","PeriodicalId":106388,"journal":{"name":"2022 IEEE 7th International Energy Conference (ENERGYCON)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130505507","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}

Global use of renewable energy sources is expected to achieve the primary purpose of energy sector development plan — reduction of greenhouse gas emissions into the atmosphere. Towards that goal, national energy development plans intend to implement a huge number of renewable energy sources and to reduce the capacity of, or shut down, fossil fuel power plants. However, the results of the latter action are not well researched. For timely reaction to avoid any accidents in the future, there is a need for comprehensive assessment of the impact of the above power plants on the power system in a long-term perspective.

Today, most of the converters use a current based control. However, due to the loss of inertia, this creates problems in network stability with an increasing number of converters in the power systems. This problem can be solved with converters, which adapt the behavior of a voltage source. The converters are operating in grid-forming mode. The Modular Multilevel Converter (MMC) provides many advantages over conventional converters, such as a high voltage quality and the elimination of filters on the ac-side. The future goal is a grid-forming MMC with a high robustness and stability. This paper provides an introduction to the controlling concept Virtual Synchronous Machine (VSM). It then compares the results of an implemented VSM controlled MMC to a synchronous generator in variational grid scenarios.","PeriodicalId":106388,"journal":{"name":"2022 IEEE 7th International Energy Conference (ENERGYCON)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116755342","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 authors demonstrate the applicability of a universal prosumer modelling object for simulating the steady-state load-flow in LEC EPSs.

The paper outline includes the method design and its micro-grid performance, which has three parallel-connected inverters. Thus, the HC implements inner, primary, and secondary control. The first, inner control loop, regulates the inverter output voltage using the stationary reference frame. On one hand, the primary control implements the universal droop control, which is in charge of active and reactive power share between inverters. On the other hand, the secondary control restores the voltage and frequency deviations because of the primary control. Finally, the results validate the advantages strategy in power inverters. The proposed control scheme effectiveness has an excellent performance, as it applied in micro-grids in the event of abrupt changes or parameter variations.","PeriodicalId":106388,"journal":{"name":"2022 IEEE 7th International Energy Conference (ENERGYCON)","volume":"253 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122091402","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}

To this end, numerous schemes have been presented based on a myriad of techniques such as public key cryptography, bilinear pairing operations, device identities and elliptic curve cryptography among others. However, many security loopholes still lurk in these protocols. In addition, performance is another serious issue that needs to be solved especially for smart gas meters. In this paper, a symmetric key based message verification protocol is presented. Extensive security evaluation is executed to show that the proposed protocol offers mutual authentication, key agreement and untraceability. It is also resilient against man-in-the-middle, verifier leakage, message replay, impersonation and known session key attacks. In terms of performance, the proposed protocol has the least communication costs and lower computation overheads compared with its peers.","PeriodicalId":106388,"journal":{"name":"2022 IEEE 7th International Energy Conference (ENERGYCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129511089","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}
