Power System Flexibility Improvement and Loss Reduction Using Optimal Restructuring of Transmission Network 利用输电网络优化重构提高电力系统灵活性和降低损耗
Ekata Kaushik, Vivek Prakash, O. Mahela
Power system flexibility (PSF) indicates the ability of a power network to reliably and cost-effectively manage the variability and uncertainty of demand and supply across all relevant time-scales. PSF has become a main topic of research due to increased penetration of renewable energy (RE) in the utility networks. Different methods and techniques have been explored for PSF improvement in the recent years. This paper is focussed to design an optimal restructuring of the practical transmission system to improve PSF. A power system restructuring flexibility index (PSRFI) is designed using the voltage deviations of all buses and fractional network loss to assess the flexibility level of the transmission system to feed quality power to the consumers. Study is performed for the base year 2021, projected 2031, and two proposals for network restructuring. Load projections have been carried out using least square approximation method. Cost benefit analysis is carried out to assess the payback period for investment incurred on the network restructuring. It is established that PSF has been improved significantly by optimal network restructuring.
电力系统灵活性(PSF)是指电网在所有相关时间尺度上可靠且经济有效地管理需求和供应的可变性和不确定性的能力。由于可再生能源(RE)在公用事业网络中的渗透增加,PSF已成为一个主要的研究课题。近年来,人们探索了不同的方法和技术来改善PSF。本文的重点是设计一种实际传动系统的优化结构,以提高PSF。利用各母线电压偏差和网损分值,设计了电力系统重构灵活性指数(PSRFI),以评估输电系统向用户提供优质电力的灵活性水平。研究以2021年为基准年,预计为2031年,并提出了两项网络重组建议。采用最小二乘逼近法进行了负荷预测。通过成本效益分析,对网络改造投资的回收期进行评估。结果表明,最优网络重构显著提高了PSF。

Nadeem Akram, V. Ilango
The Evolution of Web over the years has made a significant progress on how the information is organized and stored, as the complexity of the data stored and retrieved increases it becomes mandatory to upgrade the methodology involved in achieving them. During web Access it becomes essential to determine the nature of the user so as to understand his preferences in order to generate a customized look and feel of the website and there by offering him a Personalized web surfing experience. The primary Stage of a customized web access is in determining what the user wants from the web via a proper semantic Query Methodology which represents what user need rather than content prevailing in the web for request Query. When the user request is understood, the next task would to categorize the possible results in response to the query depending upon relevance. Furthermore, the process would be to categorize user data according different aspects to create web personalization. This takes the web to next level with web usage prediction using Web log files there by creating a New Customized web for every one with the major focus to represent what matters to the users.
多年来,Web的发展在如何组织和存储信息方面取得了重大进展,随着存储和检索数据的复杂性的增加,升级实现这些信息所涉及的方法变得势在必行。在网络访问过程中,确定用户的性质以了解他的偏好变得至关重要,以便生成定制的网站外观和感觉,并为他提供个性化的网络冲浪体验。定制化web访问的初级阶段是通过适当的语义查询方法来确定用户想要从web获得什么,这种方法代表了用户需要什么,而不是在请求查询的web中流行的内容。理解用户请求后,下一个任务将根据相关性对响应查询的可能结果进行分类。此外,这个过程将根据不同的方面对用户数据进行分类,以创建web个性化。这将网络带入了一个新的水平,通过使用网络日志文件来预测网络使用情况,为每个人创建一个新的定制网络,主要关注的是代表什么对用户重要。

Research on Zero and Low Speed Startup of Synchronous Reluctance Motor Based on High Frequency Injection Method 基于高频注入法的同步磁阻电机零、低速启动研究
Dengke Li
For synchronous reluctance motors, there are more and more researches on position sensorless vector control. However, when starting at zero speed or low speed, some problems are often encountered. These problems often affect the overall control effect of the synchronous reluctance motor. To improve the control effect, this paper studies the starting effect of the synchronous reluctance motors. Using the salient pole characteristics of the synchronous reluctance motors, the method used in this article is the rotation high-frequency voltage signal injection method. The high-frequency sine (cosine) signal is injected into two-phase stationary coordinate system of the motor at the same time. The actual rotor position angle will be obtained from the response current. Simulation uses this method and the simulation results respectively show the zero-speed and low-speed startup effects. This method can accurately estimate the rotor angle and realize zero-speed and low-speed starting. These results verify the correctness of the method.
对于同步磁阻电机,无位置传感器矢量控制的研究越来越多。但在零速或低速起动时,往往会遇到一些问题。这些问题往往会影响同步磁阻电动机的整体控制效果。为了提高同步磁阻电动机的控制效果,本文对同步磁阻电动机的起动效果进行了研究。利用同步磁阻电动机的凸极特性,本文采用的方法是旋转高频电压信号注入法。同时将高频正弦(余弦)信号注入电机的两相静止坐标系。实际转子位置角由响应电流得到。采用该方法进行了仿真,仿真结果分别显示了零速和低速启动效果。该方法可以准确估计转子角度,实现零速和低速起动。这些结果验证了该方法的正确性。

S. Prabha, K. Chandu, Anusha Sairam, M. V. Ratna kumar, K. Sankaran
Abnormal cell growth in brain causes brain tumor which may be a cancerous or non-cancerous one. Tumors can start in the brain, or cancer elsewhere in the body can spread to the brain. This tumor has to be detected at an early stage when it is small. Tumor can be detected easily with the help of MRI modality as the resolution and quality of an image is superior in MRI liken with other imagining techniques and also it is not harmful for the tissues that are present in the brain. In our proposed methodology, three sections have been implemented which includes segmentation, feature extraction and classification. Employment of region based active contour algorithm is used to identify the type of tumors as malignant and benign. Thus, proposed system classifies tumor with an accuracy of 93.34 %.

Optimal Conserve Inventory from One Outturn Gizmos to Two Intake Gizmos When Inter-Arrival Breakdown is a Random Variable 当到达间故障是一个随机变量时,从一个输出装置到两个输入装置的最优保存库存
M. Paul, S. Tamilselvan, T. Venkatesan
In inventory control theory the one of the important model is to estimate the conserve inventory when the stations are in series. In this model a system with two nodes are suggested. In the first phase it is assumed that there is only machine A1 and the second phase as two machines say $B_{2}^{1}$ and $B_{2}^{11}$. The machines in the second stage may have same or different process types. During the breakdown time of the machine in the first stage a reserve inventory is maintained to ensure uninterrupted production in the next stage. This conserve inventory is needed as otherwise; the machines in the second stage may become idle which will impact not only the profits but also bring loss due to non-functioning of machines. Mathematical models has been derived for obtaining conserve inventory by treating repair time and inter arrival time as random variables
在库存控制理论中,一个重要的模型是对库存的估计。在该模型中,提出了一个具有两个节点的系统。在第一阶段,假设只有机器A1,第二阶段有两台机器,分别是$B_{2}^{1}$和$B_{2}^{11}$。第二阶段的机器可能具有相同或不同的工艺类型。在第一阶段的机器故障期间,保持储备库存,以确保下一阶段的生产不间断。这样节约库存是必要的;第二阶段的机器可能会闲置,这不仅会影响利润,还会因为机器不能运行而带来损失。将维修时间和间隔到达时间作为随机变量,建立了库存守恒的数学模型

Charging and Discharging of Battery in a PV System using Fuzzy Logic Controller 利用模糊逻辑控制器为光伏系统中的电池充电和放电
Atul Nayan, O. P. Rahi
Microgrids are the major component of the future smart grid, as these open up new possibilities for aggregating loads and sources. As a result, it is considered to be the next-generation power system arrangement, capable of operating in both standalone and grid-connected modes. This work describes a novel fuzzy logic controller for controlling the charging and discharging of a PV battery storage system. The battery is charged and discharged based on the power difference between generation and demand. There are numerous strategies for controlling the performance of battery, however these controlling techniques have issues in terms of limiting overcharging, complexity in control and slow charging. The paper compares the performance of battery, simulated in MATLAB Simulink using PID controller and fuzzy logic controller. A fuzzy logic controller is less complex to design and provides fast charging.

A Time-Series Based Yield Forecasting Model Using Stacked Lstm To Predict The Yield Of Paddy In Cauvery Delta Zone In Tamilnadu 基于时间序列的层叠Lstm水稻产量预测模型在泰米尔纳德邦Cauvery三角洲地区的应用
M. Geetha, R. Suganthe, S Roselin Nivetha, R. Anju, R. Anuradha, J. Haripriya
Cauvery delta zone in Tamilnadu is called as “Nerkazhanchiyam” (the land of Paddy) of the state, as it has the potential to produce paddy in huge quantity that can be suffice the need of the state. This zone includes the districts such as Thanjavur, Tiruvarur, Nagapattinam, Trichy and Cuddalore. These districts account for about 53% of production of paddy in the state. Increasing the production of paddy in Cauvery Delta Zone would satisfy the requirement of rice in the state on the whole. This will also have a substantial influence on both the farmer's and the nation's economy. Forecasting the production of crops beforehand could assist the farmers in improving their productivity. This necessitates the design of a precise crop yield prediction model. Crop production in agriculture is primarily determined by a variety of factors that falls under three categories: technological (agricultural techniques, managerial decisions, etc.), biological (diseases, insects, pests, etc.), and environmental (climate change, etc.). Among these factors environmental factors pose a great challenge to the decision makers in developing a precise prediction model. Hence, it is proposed to develop a suitable yield prediction model to predict the yield of paddy in Cauvery delta region considering the environmental factors along with the supplied nutrients. The proposed prediction model makes use of Long Short Term Memory (LSTM) algorithm which is a popular deep learning algorithm, to forecast the yield of paddy. LSTM is well known for its better prediction using time series data. Performance of the proposed prediction model is measured using the training loss and validation loss.
泰米尔纳德邦的Cauvery三角洲地区被称为“Nerkazhanchiyam”(水稻之乡),因为它有潜力生产大量的水稻,可以满足该邦的需求。该地区包括Thanjavur、Tiruvarur、Nagapattinam、Trichy和Cuddalore等地区。这些地区的水稻产量约占该邦总产量的53%。在高韦里三角洲地区增加水稻产量,总体上可以满足国家对水稻的需求。这也将对农民和国家的经济产生重大影响。提前预测作物产量可以帮助农民提高生产力。这就需要设计一种精确的作物产量预测模型。农业作物生产主要由各种因素决定,这些因素可分为三类:技术(农业技术、管理决策等)、生物(疾病、昆虫、害虫等)和环境(气候变化等)。在这些因素中,环境因素对决策者如何建立精确的预测模型提出了很大的挑战。因此,建议建立一种适合高韦里三角洲地区的水稻产量预测模型,考虑环境因素和供给养分。该预测模型利用一种流行的深度学习算法——长短期记忆(LSTM)算法对水稻产量进行预测。LSTM以使用时间序列数据进行更好的预测而闻名。利用训练损失和验证损失来衡量所提出的预测模型的性能。

Analysis of Capacity and Outage Probability for NOMA based Cellular Communication over Rician Fading Channel 基于NOMA的蜂窝式衰落信道通信容量和中断概率分析
Veeraiyah Thangasamy, I. Singh, Karishma, Yaswanth, Jathin Sai
Non-Orthogonal multiple access (NOMA) scheme serves as a favorable technology for 5G and beyond cellular networks as compared to orthogonal multiple access (OMA) scheme. Multipath fading also affects the performance of wireless communication system. So as to exploit the features of NOMA technique, it is vital to identify and analyze its performance over various fading channels. This paper provides the performance analysis of NOMA based cellular system over two key parameters named as channel capacity and outage probability. Rician fading distribution has been considered for multipath fading. Rician fading channel is much suitable when at least one communication link fallow a line-of-sight (LoS) path and the signal strength is much stronger than other paths. An analytical expression for channel capacity and outage probability has been derived for considered system model.

与正交多址(OMA)方案相比,非正交多址(NOMA)方案是5G及以上蜂窝网络的有利技术。多径衰落也影响着无线通信系统的性能。为了充分利用NOMA技术的特点,对其在各种衰落信道下的性能进行识别和分析至关重要。本文通过信道容量和中断概率两个关键参数对基于NOMA的蜂窝系统进行了性能分析。在多径衰落中考虑了梯度衰落分布。当至少有一条通信链路处于视距路径下,且信号强度比其他路径强得多时,采用线性衰落信道是非常合适的。针对所考虑的系统模型,导出了信道容量和中断概率的解析表达式。通过曼特卡罗仿真,得到了使用该衰落信道的信道容量和中断概率的仿真结果。给出了近端和远端用户信道容量和中断概率的仿真结果比较。

This paper provides the performance analysis of NOMA based cellular system over two key parameters named as channel capacity and outage probability. Rician fading distribution has been considered for multipath fading.

数据共享是CC提供的一种有益的经济援助,信息实质安全也由此产生,因为信息被转移到一些云工作者手中。确保敏感和重要的数据;使用不同的程序来改进对集体信息的访问管理。在这里,基于密码文本-策略属性的加密(CP-ABE)可能会使它非常有用和安全。传统的cp - abe只关注信息隐私;鉴于客户的人身安全保护目前是一个重大问题。CP-ABE通过隐藏访问(HA)策略确保了信息的隐私性,也确保了客户端的保护不被暴露。然而,由于通信开销和计算成本的原因,目前绝大多数的方案都是无效的。此外,该机制的绝大部分都没有考虑能力验证或能力验证阶段的安全溢出问题。为了解决上述问题,本文提出了一种安全保护scp - abe的方法,该方法采用熟练影响认证。此外,它的私钥实现了一致的大小。同时,建议方案完成了具体的安全决策中的n-BDHE问题和决策直接推定。计算结果证实了所引入方法的有效性。
