Under the net-zero carbon transition, lithium-ion batteries (LIB) plays a critical role in supporting the connection of more renewable power generation, increasing grid resiliency and creating more flexible energy systems. 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).
在净零碳转型下,锂离子电池(LIB)在支持连接更多可再生能源发电、提高电网弹性和创建更灵活的能源系统方面发挥着关键作用。然而,电池较短的使用寿命和相对较高的成本阻碍了电池技术的广泛采用,例如可再生资源存储。此外,电池的使用寿命受材料组成、系统设计和操作条件的影响很大,因此对电池系统的控制和管理更具挑战性。数字化和人工智能(AI)为建立电池数字孪生体提供了机会,该孪生体在提高电池管理系统的态势感知能力和实现电池存储单元的最佳运行方面具有巨大潜力。准确估计充电状态(SOC)可以指示电池的状态,为维护提供有价值的信息,并最大限度地延长其使用寿命。本文提出了一种基于LSTM(长短期记忆)和EKF(扩展卡尔曼滤波)相结合的混合模型的数字双驱动框架来估计锂离子电池的SOC。LSTM为EKF提供了更准确的初始SOC估计和阻抗模型数据。实验结果表明,与传统方法相比,所开发的电池数字孪生模型对初始SOC条件的依赖较小,并且具有更低的RMSE(均方根误差),具有更强的鲁棒性。

This paper explores variables for NILM dataset creation, focusing on the relationship between measurement frequency, dataset weight, micro and macro characteristics, and prepossessing. Measurements show that a frequency of 2 kHz allows micro analysis by FFT decomposition and high resolution macro analysis by 0.02 s resampling. Storing only features of interest such as events or harmonic frequencies show potential for diminishing the weight of the dataset while keeping insightful data.

The increased integration of distributed generation into the distribution grid poses technical and economic challenges for asset owners and grid operators. One possible solution to mitigate these issues is local energy communities (LEC). The authors provide an overview of the issues arising from increased distributed generation, a classification of the electric power systems (EPS) used in LECs and insight into actual research topics. The authors demonstrate the applicability of a universal prosumer modelling object for simulating the steady-state load-flow in LEC EPSs. The modelling framework enables the DSO to understand better the impacts of and requirements for LECs on the low voltage distribution network. The used approach provides a flexible and straightforward way to model power flow in LEC power systems, thus reducing the required resources for object modelling and control system integration.

A novel control strategy is proposed in this paper, which implements a Hierarchical Control (HC) and Space Vector Pulse Width Modulation (SVPWM). 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.

The further domination of converter-based generation in power systems comes along with the loss of conventional power plants. 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.
随着传统发电厂的消失,基于变流器的发电在电力系统中进一步占据主导地位。今天,大多数转换器使用基于电流的控制。然而,随着电力系统中变流器数量的不断增加,由于惯性的丧失,这会给网络稳定性带来问题。这个问题可以用变换器来解决,它可以适应电压源的行为。变流器以网格形成模式运行。模块化多电平转换器(MMC)与传统转换器相比具有许多优点,例如高电压质量和消除交流侧滤波器。未来的目标是一个具有高鲁棒性和稳定性的网格形成MMC。介绍了虚拟同步机(VSM)的控制概念。然后将实现的VSM控制的MMC与变分电网场景下的同步发电机的结果进行比较。

This paper demonstrates that when thermal part of thermoelectric generator (TEG) is reflected to electric load side, resulting circuit is similar to low frequency equivalent of photovoltaic (PV) generator. Derivation of equivalent circuit is presented and verified in simulation of example system. It may then be concluded that ambient energy sources exhibit similar characteristics even when different energy types are examined. Parallels can then be drawn between the two energy sources and known PV control methodologies can be utilized in TEG applications.

Development plans in the energy sector of European countries assume modifications almost in all fields of energy systems. 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. This article focuses on the reasonableness of conventional power plants in the energy systems of the Baltic countries in 2050.
欧洲国家能源部门的发展计划几乎在能源系统的所有领域都作了修改。全球利用可再生能源有望实现能源部门发展计划的主要目的——减少向大气中排放的温室气体。为了实现这一目标,国家能源发展计划打算实施大量可再生能源,并减少或关闭化石燃料发电厂的产能。然而,后一种行动的结果并没有得到很好的研究。为了及时应对,避免未来发生事故,需要从长远的角度对上述电厂对电力系统的影响进行综合评估。本文重点讨论了2050年波罗的海国家能源系统中常规发电厂的合理性。

Conventional navigational buoys are powered by solar panels which need to be maintained frequently, thereby increasing the cost of maintenance. Additionally, solar panels are dependent on the availability of sunlight which is limited to a certain time of the day. An alternative approach is to use wave energy based navigational buoys which depend on the energy generated by surface waves in the ocean. For large-scale exploitation of the offshore wave energy source, navigational buoys require turbines which should be able to withstand varying pressures while simultaneously react to the pressure difference of the waves, thereby generating electricity. In this paper, an optimized design for unidirectional impulse turbine previously used in a Backward Bent Ducted Buoy (BBDB) has been proposed. The proposed design has higher structural strength while maintaining the basic performance capabilities. It was observed that using aluminum alloy AlSi7 Mg0.6 instead of conventionally used polycarbonate material improves the structural strength of the designed turbine while maintaining it’s weight (~9 % increase) so that the problem of inertia while self initiating is kept at bay. The analysis of the rotor for the stresses was carried out using Ansys 18.2.
传统的导航浮标由太阳能电池板供电,需要经常维护,从而增加了维护成本。此外,太阳能电池板依赖于阳光的可用性,而阳光在一天中的特定时间是有限的。另一种方法是使用基于波浪能的导航浮标,这种浮标依靠海洋表面波浪产生的能量。为了大规模开发近海波浪能源,导航浮标需要能够承受不同压力的涡轮机,同时对波浪的压力差作出反应,从而发电。本文提出了一种用于后弯导管浮标(BBDB)的单向脉冲涡轮的优化设计方法。提出的设计方案在保持基本性能的同时,具有较高的结构强度。结果表明,采用铝合金AlSi7 Mg0.6代替传统的聚碳酸酯材料,提高了涡轮的结构强度,同时保持了涡轮的重量(增加了9%),从而解决了自启动时的惯性问题。利用Ansys 18.2软件对转子进行了应力分析。

It was observed that using aluminum alloy AlSi7 Mg0.6 instead of conventionally used polycarbonate material improves the structural strength of the designed turbine while maintaining it’s weight (~9 % increase) so that the problem of inertia while self initiating is kept at bay. The analysis of the rotor for the stresses was carried out using Ansys 18.2.","PeriodicalId":106388,"journal":{"name":"2022 IEEE 7th International Energy Conference (ENERGYCON)","volume":"41 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":"131008107","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}

SCADA is the abbreviation for “Administrative Control And Data Acquisition.” SCADA frameworks are generally utilized in industry for administrative control and information securing of modern cycles. Regular SCADA frameworks use PC, journal, slim client, and PDA as a client. In this paper, a Java-empowered cell phone has been utilized as a client in an example SCADA application to show and regulate the place of an example model crane. The paper presents a genuine execution of the on-line controlling of the model crane through cell phone. The remote correspondence between the cell phone and the SCADA server is performed through a base station by means of general parcel radio assistance GPRS and remote application convention WAP.This application can be used in industrial sites at areas that are likely to be exposed to a security emergency (like terrorist attacks) which causes the sudden exit of the operators, however, no time to perform the shut down procedures for the plant.Hence this application allows shutting down units and equipment remotely by mobile, and so avoids damage and losses.
SCADA是“行政控制和数据采集”的缩写。SCADA框架通常用于工业管理控制和现代循环的信息安全。常规SCADA框架使用PC、日志、瘦客户机和PDA作为客户机。本文在一个SCADA示例应用中,利用一个java支持的手机作为客户端,对示例模型起重机的位置进行显示和调节。本文介绍了一种通过手机对模型起重机进行在线控制的真实实现方法。手机与SCADA服务器之间的远程通信是通过基站通过通用包无线电辅助GPRS和远程应用协议WAP实现的。该应用程序可用于工业现场,在可能暴露于安全紧急情况(如恐怖袭击)的区域,导致操作员突然退出,但是没有时间执行工厂的关闭程序。因此,该应用程序允许通过移动设备远程关闭单元和设备,从而避免损坏和损失。
