Solar power generation is highly intermittent, nonlinear, and variable in nature. The increase in penetration level of solar energy resources poses technical challenges. An accurate forecasting model is crucial to minimizing these technical issues. Therefore, choosing the right forecasting technique for the right forecasting horizon is vital. In this study, the performance analysis of machine learning and time series forecasting techniques for various forecasting horizons has been investigated. Its accuracy, root mean square error (RMSE), and mean absolute error (MAE) have been compared to other techniques.

Numerous data analytic techniques have been employed by the United States Navy for air conditioning (AC) plant condition-based maintenance. The developed diagnosis models include physics-based and data-driven approaches, particularly regression models have shown that AC plants operating conditions could be correctly diagnosed for poor conditions or faults. However, building effective condition-based maintenance models for AC plants faults prognosis based on classification has not been explored in-depth. This paper presents a comparative study of machine learning classification techniques that produces solutions that are as effective and better than solutions produced by the physics-based and regression approaches.

In this paper, a Three-Dimensional (3D) Computational Fluid Dynamic (CFD) simulation of a biomimetic robot fish is studied. The OpenFOAM software is used to define the movement of the robot fish and the dynamic mesh is used to mimic the fish swimming in water. Hydrodynamic analysis has been done to analyze the motion of the robot in water. Furthermore, this paper provides comparative data about hydrodynamic properties to improve the design, remote control, and flexibility of the underwater robot fish. In addition, it discusses how the fish oscillates the tail and the caudal fin to push water away behind it and get the thrust pushing it forward.

Sustainability is a vast subject involving various research areas. Emerging technologies, through their development and the possibilities they offer, impact sustainability. In particular, Artificial Intelligence and Machine Learning have been trendy research subjects for almost a decade now. They offer a wide range of potential applications, including energy efficiency and Intelligent Transportation Systems, two key elements for Smart Cities. All these developments seem to put AI in a favorable position to build Sustainability. However, AI’s own ecological impact and carbon footprint is disastrous and drastic changes must be done if this technology is to be used in a sustainable future. This paper offers a short overview of AI potential for sustainability, in the context of Smart cities. Then the drawbacks of AI energy consumption are highlighted. New ways and methodologies are proposed to create greener AI.

Decentralized Peer-to-Peer Energy Trading Model for Networked Microgrids 网络化微电网分散式点对点能源交易模型

Energy trading among networked microgrids can be an effective tool to achieve reliability and economic benefits. This paper proposes a two stage Peer-to-Peer (P2P) energy trading model consisting of a local scheduling optimization problem in stage one and an energy trading price adjustment mechanism in stage two. In this study, it was assumed that all networked microgrids are connected to the utility grid and to each other. However, the amount of power that can be exchanged with the utility grid is limited by the tie-line maximum capacity; hence, the trading scheme is developed for energy trading between the networked microgrids to satisfy their deficit and surplus power that cannot be exchanged with the utility grid due to tie-line limit. Simulation is conducted to validate the proposed model using a 24-hour forecasted net load data for seven networked microgrids.
网络化微电网之间的能源交易是实现可靠性和经济效益的有效手段。本文提出了一个两阶段的P2P能源交易模型,该模型包括第一阶段的局部调度优化问题和第二阶段的能源交易价格调整机制。在本研究中,假设所有联网微电网都连接到公用电网并相互连接。然而,可以与公用电网交换的电量受到联络线最大容量的限制;为此,本文提出了一种用于联网微电网之间能源交易的交易方案,以满足微电网因联络线限制而无法与公用电网交换的亏余电力。利用7个联网微电网的24小时预测净负荷数据进行了仿真,以验证所提出的模型。

There is a general consensus that the future of green jobs looks bright. High schoolers interested in pursuing careers in the field, especially the energy sector, will enhance their candidacy through opportunities that augment classroom learning and combine theory with practical application. One such program is "Create a Spark" offered by Chicago-based Commonwealth Edison (ComEd). This program is designed to encourage an energy mindset, which involves prioritizing energy stewardship and serving as an energy ambassador for the community. The capstone experience in Create a Spark is a sustainable home design challenge that teaches high school students the fundamentals of residential energy efficiency and how to maximize efficiency. Create a Spark, and the Energy House Challenge in particular, have been well-received by high school participants. The Energy House Challenge was rated among the most interesting components of Create a Spark programming. There were statistically significant post-program increases on two dimensions of the energy mindset: knowing how to educate others to make informed energy decisions, and self-reported education of family and community members on how to make informed energy decisions. These results indicate the potential for future success in building energy mindset through short-term out-of-school programming that focuses on hands-on learning and mentorship.
人们普遍认为,绿色工作的未来看起来很光明。有兴趣从事该领域职业的高中生,特别是能源部门,将通过增加课堂学习和将理论与实际应用相结合的机会提高他们的候选人资格。芝加哥联邦爱迪生公司(ComEd)提供的“创造火花”就是这样一个项目。该项目旨在鼓励一种能源心态,其中包括优先考虑能源管理,并担任社区的能源大使。Create a Spark的顶点体验是一个可持续的家居设计挑战,教给高中生住宅能源效率的基础知识以及如何最大限度地提高效率。“创造火花”,尤其是“能源之家挑战”,受到了高中参与者的好评。能源屋挑战赛被评为Create a Spark编程中最有趣的部分之一。在统计上,项目结束后,在能源心态的两个维度上有了显著的提高:知道如何教育他人做出明智的能源决策,以及自我报告的家庭和社区成员如何做出明智的能源决策的教育。这些结果表明,通过注重实践学习和指导的短期校外项目,未来在建立能源思维方面有可能取得成功。

High-Endurance UAV Via Parasitic Weight Minimization and Wireless Energy Harvesting 基于寄生重量最小化和无线能量收集的高续航无人机

This paper discusses the on-going investigation of novel technologies for increasing the endurance of UAVs, mainly by increasing power-to-weight ratio through parasitic weight reduction of structural and power systems and generating/harvesting energy mid-flight. Electrically-powered UAVs are typically limited in range and mission time due to the limited capacity of existing technologies. The benefit of increased endurance is the ability to provide virtually nonstop surveillance over an area, which has both commercial and military applications. The student engineering team at the California State Polytechnic University, Pomona have been working on this multi-year, multidisciplinary project to integrate a variety of technologies into an existing RC aircraft. Flexible solar panels that double as wing skin, vibrational kinetic energy generators, in-flight induction wireless recharging and thermoelectric generators are the four main methods of generating power during flight. To store the power, the wing spars double as the main batteries and structural supercapacitors could replace the lower wing skin. These storage devices reduce parasitic weight by doubling as aircraft structural components, therefore forming a "flying battery". An intelligent power management system was developed to accept the AC and DC power sources and maximize re-charge rate by alternating which battery is charged at a given time.
本文讨论了正在进行的增加无人机续航力的新技术研究,主要是通过减少结构和动力系统的寄生重量以及在飞行中产生/收集能量来提高功率重量比。由于现有技术的能力有限,电动无人机通常在航程和任务时间上受到限制。续航时间增加的好处是能够在一个区域内提供几乎不间断的监视,这在商业和军事上都有应用。加州州立理工大学波莫纳分校的学生工程团队一直致力于这个多年的多学科项目,将各种技术集成到现有的RC飞机中。柔性太阳能板兼作翼皮、振动动能发电机、飞行中感应无线充电和热电发电机是飞行中发电的四种主要方法。为了储存能量,翼梁兼作主电池,结构超级电容器可以取代下翼表皮。这些存储设备通过充当飞机结构部件来减少寄生重量,从而形成“飞行电池”。开发了一种智能电源管理系统,可以接受交流电源和直流电源,并通过在给定时间交替充电来最大化再充电率。

Electric power system operators can manage distribution system reliability by coordinating end customer usage of distributed energy resources. The end customers in this regard are Service Provisioning Customers, who provide their energy resources to a Grid Service Provider, which in turn dispatches large aggregations of distributed energy resources to provide reliable service to the power system.The security of this system relies upon information protection mechanisms, as described in IEEE 2030.5. However, in addition to preventive security measures, a monitoring function is required to ensure trustworthiness. Trust models are a method to detect and respond to both expected and unexpected behavior. Different trust models are required for various types and characteristics of each situation. This paper will describe the topics that must be considered when developing a trust model as it applies to distributed energy resources. The major contribution of this paper is the creation and application of a Distributed Trust Model applied to distributed energy resources.
电力系统运营商可以通过协调终端用户对分布式能源的使用来管理配电系统的可靠性。最终客户是业务发放客户,将自己的能源提供给电网服务提供商,由电网服务提供商调度大量的分布式能源,为电力系统提供可靠的服务。该系统的安全性依赖于IEEE 2030.5中描述的信息保护机制。但是,除了预防性安全措施之外,还需要监控功能来确保可靠性。信任模型是一种检测和响应预期和意外行为的方法。每种情况的不同类型和特征需要不同的信任模型。本文将描述在开发适用于分布式能源的信任模型时必须考虑的主题。本文的主要贡献是建立并应用了分布式能源的分布式信任模型。

Some of the recent reports show that Power Grid is a target of attack and gradually the need for understanding the security of Grid network is getting a prime focus. The Department of Homeland Security has imposed focus on Cyber Threats on Power Grid in their "Cyber Security Strategy,2018" [1] . DHS has focused on innovations to manage risk attacks on Power System based national resources. Power Grid is a cyber physical system which consists of power flow and data transmission. The important part of a microgrid is the two-way power flow which makes the system complex on monitoring and control. In this paper, we have tried to study different types of attacks which change the data propagation of Synchrophasor, network communication interruption behavior and find the data propagation scenario due to attack. The focus of the paper is to develop a platform for Synchrophasor based data network attack study which is a part of Microgrid design. Different types of intrusion models were studied to observe change in Synchrophasor data pattern which will help for further prediction to improve Microgrid resiliency for different types of cyber-attack.
最近的一些报告表明,电网是攻击的目标,对电网网络安全性的认识逐渐成为人们关注的焦点。国土安全部在其“2018年网络安全战略”中重点关注电网的网络威胁[1]。国土安全部专注于创新,以管理基于国家资源的电力系统风险攻击。电网是一个由潮流和数据传输组成的网络物理系统。微电网的重要组成部分是双向潮流,这使得系统的监测和控制变得复杂。在本文中,我们试图研究不同类型的攻击,这些攻击改变了同步量的数据传播,网络通信中断行为,并找到了由于攻击而导致的数据传播场景。本文的重点是开发一个基于同步相量的数据网络攻击研究平台,这是微电网设计的一部分。研究不同类型的入侵模型,观察同步量数据模式的变化,有助于进一步预测,提高微电网对不同类型网络攻击的弹性。

Different types of intrusion models were studied to observe change in Synchrophasor data pattern which will help for further prediction to improve Microgrid resiliency for different types of cyber-attack.","PeriodicalId":127126,"journal":{"name":"2021 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125033355","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 Smart grid technology uses the integration of communication, automation, and power sources to assure a safe and reliable electric grid. Integrating new technologies to the electric grid will result a grid with more efficient and reduce the down time for a distribution line due to single or multiple faults. Our proposed automated system will work to monitor and control a real-world like model of a smart grid for AC distribution lines. A microcontroller will be reading the information derived by the current sensors to continuously detect sudden changes in current. When fault occurs in the system it will be detected by the sensor and communication mechanism. The computing station will automatically communicate with relays to isolate the fault. Once the fault has been isolated, the fault indicator will be triggered and a notification about detection and localization of fault will be issued.
智能电网技术利用通信、自动化和电源的集成来保证电网的安全可靠。将新技术集成到电网中将使电网效率更高,并减少由于单个或多个故障导致的配电线路停机时间。我们提出的自动化系统将用于监测和控制与现实世界类似的交流配电线路智能电网模型。微控制器将读取由电流传感器导出的信息,以连续检测电流的突然变化。当系统发生故障时,通过传感器和通信机制进行检测。计算站将自动与继电器通信以隔离故障。故障被隔离后,将触发故障指示灯,并发出故障检测和定位通知。
