The aim of the paper is to investigate the effect of electricity conservation nudge on the system cost and revenue of prosumers in local electricity market. To motivate the prosumers for energy conservation, a socio economic aspect is considered in terms of social nudge. The mixed integer linear programming problem is modeled considering economics at the center of objective function. The experiment is carried out for 40 prosumers in four different cases including base case. These cases are created based on the empirical reaction of prosumers on receiving the social nudge for electricity saving. The system cost and revenue generated by prosumers are compared for various cases. The highest cost saving of 14.92% is obtained. The results reveal that inclusion of socio economic aspect in local electricity market has tremendous potential to enhance the system operation. Moreover, the propose approach could be very helpful in increasing the willingness of consumers to become a prosumer by participating in local electricity market, and hence improve environmental ecology.

Over a decade, significant increase in generation of electricity from wind has been seen. Efficient increase in the integration of wind energy can be achieved by utilizing highly efficient and reliable wind turbines. Amid the various turbine available for wind extraction PMSG is one of the most promising technologies used nowadays. It allows variable speed operation with high efficiency. To achieve this, various control techniques are used for optimal power extraction. This paper proposes control techniques of pitch angle control (PAC) on the generator side and voltage-oriented control (VOC) on the grid side to achieve optimal power extraction for variable wind speed operation. In this paper, the study is carried out using simulation in MATLAB/SIMULINK and the effectiveness of the proposed control techniques is validated in real-time using the OPAL-RT simulator.

As climatic crisis increasing in the world due to the increasing pollution day by day, in which one of the important contributor is the increasing demand for energy,it has been found that 25 percent of the global energy consumption is only due to transportation sector, so in order to minimize the effect due to transportation sector we have to shift from Internal Combustion Engine (ICE) to battery based Electric Vehicle (EVs), there are several issues that need to be addressed to encourage the adoption of EVs on large scale, one of the severe effect due to large scale adoption of EVs is on the grid, large scale deployment of EVs causes overloading on the power grid due to the unscheduled charging of the EVs, in order to reduce this overloading of the grid proper scheduling algorithm are needed by which we can scheduled the charging of EVs and growing public charging demand for EVs. For this data-driven tools can be utilized which can predict the various parameters like energy consumption, time of charging, whether the EVs use charging stationtomorrow, use of DC fast charging etc, in this paper we are focusing on the prediction of energy consumption by using the historical charging data of the EVs by using various popular machine learning (ML) algorithm such as Random Forest, XGboost, linear Regression, ANN and DNN. The best predictive results are obtained by Random Forest and XGboost, and various result of past work is also discussed.
由于污染日益增加,世界气候危机日益严重,其中一个重要因素是对能源的需求不断增加,已经发现全球能源消耗的25%仅来自交通运输部门,因此为了最大限度地减少交通运输部门的影响,我们必须从内燃机(ICE)转向基于电池的电动汽车(ev)。有几个问题需要解决,鼓励采用大规模电动汽车,严重的影响由于电动汽车大规模采用网格,大规模部署的电动汽车超载对电网造成由于计划外充电的电动汽车,以减少这个重载的网格需要适当的调度算法,我们可以将电动汽车的充电和不断增长的公共收费对电动汽车的需求。为此,可以利用数据驱动的工具来预测各种参数,如能耗、充电时间、电动汽车明天是否使用充电站、使用直流快速充电等,在本文中,我们重点利用各种流行的机器学习(ML)算法,如随机森林、XGboost、线性回归、ANN和DNN,利用电动汽车的历史充电数据来预测能耗。随机森林和XGboost的预测效果最好,并对以往工作的各种结果进行了讨论。

For reliable operation, the detection of fault as well as its location are two important challenges to power engineers. This paper presents an approach to focus on judging the location of buses in a power network where faults occurred. A network having radial busfeeder combinations was considered and data are collected from different buses. Then, wavelet decomposition was done. Different coefficients obtained from the results of signal decomposition were scrutinized by their nature of distribution in terms of Kurtosis and Skewness. Then, different machine learning topologies were applied to network signals for discrimination. They are tested with unknown data sets having a different percentage of randomness and compared. One method is found best that shows a high level of accuracy suitable for judgement of the location where faults occurs.

This paper presents a high-gain DC-DC converter for a rooftop solar photovoltaic (SPV) system with a multifunctional grid-tied inverter. In order to achieve a smooth integration of roof-top SPV with the utility grid, a high gain DCDC converter is required to boost up to a higher voltage gain, to reduce ripple voltage, and switching stress at the DC bus. Further, this higher gain DC voltage is converted into a three-phase AC voltage of the demanded utility grid by a multifunctionality grid-tied inverter (MFGTI). Hence for integrating the SPV with the utility grid, there are challenges to overcome, such as keeping the grid synchronized, and power quality issues under nonlinear load, & solar irradiation conditions. A modified synchronous reference frame (SRF) control technique is proposed to make the MFGTI capable to inject the active power from SPV into the utility grid. Simultaneously compensate the reactive power, and the current harmonics to improve the PF within the IEEE standard 519-2022. The proposed system is implemented using MATLAB®/Simulink software, and it is evaluated under various solar irradiation, and nonlinear load conditions.
提出了一种用于屋顶太阳能光伏(SPV)系统的高增益DC-DC变换器,该变换器具有多功能并网逆变器。为了实现屋顶SPV与公用电网的平滑集成,需要一个高增益的DCDC转换器来升压到更高的电压增益,以降低纹波电压和直流母线的开关应力。此外,这种高增益的直流电压通过多功能并网逆变器(MFGTI)转换成所需公用电网的三相交流电压。因此,为了将SPV与公用电网集成,需要克服一些挑战,例如保持电网同步,以及非线性负载和太阳辐照条件下的电能质量问题。提出了一种改进的同步参考框架控制技术,使MFGTI能够将SPV的有功功率注入公用电网。同时补偿无功功率和电流谐波,提高PF在IEEE标准519-2022内。利用MATLAB®/Simulink软件实现了该系统,并在各种太阳辐照和非线性载荷条件下对其进行了评估。

Renewable energy sources have emerged as a viable option to meet the rising energy demand, slow down climate change, and promote sustainable development. This paper offers a collection of unique solutions that permit information interchange between the consumers and the distributed generating center, which state that they need to be managed effectively. The integration of these systems is performed in a distributed manner using microgrid systems. In microgrids, the energy management system should be able to guide and provide efficient control to ensure power supply reliability by both the generation and distribution systems at the lowest possible operating cost. The application of renewable energy sources for energy management in a microgrid system is discussed in this paper, along with performance analysis and a look at the impact of load variation on system performance.

Diabetes is a disorder of the metabolism caused by high glucose levels in the body. Diabetes causes eye deficiency, also known as Diabetic Retinopathy (DR), which causes significant vision loss over time. Diabetes patients’ vision can be saved if DR is detected and diagnosed early. Microaneurysms, haemorrhages, and exudates are prior signs of DR that emerge on the surface of retina. Nevertheless, diagnosing DR is a challenging problem that necessitates the services of an experienced ophthalmologist. Using an automated classifier, an artificial intelligence based deep learning can assist the ophthalmologist in providing an expert advice related to the assessment of the DR. A large volume of data is required to effectively train the model for the classification of DR, that is a major constraint in the DR area. Transfer learning is a methodwhich could assist in combating image limitation. The central idea behind transfer learning approach is that, this framework was already trained on large set of images which could be fine-tuned to fit for the required set of data. This paper applied transfer learning based VGG16 and InceptionV3 model for the DR classification on a public benchmark IDRiD dataset (Indian Diabetic Retinopathy Image Dataset). These models are used to address the problem and to maximize the results.
糖尿病是一种由体内高血糖引起的代谢紊乱。糖尿病会导致视力不足,也被称为糖尿病视网膜病变(DR),随着时间的推移会导致严重的视力丧失。如果早期发现和诊断DR,可以挽救糖尿病患者的视力。视网膜表面出现的微动脉瘤、出血和渗出物是DR的前兆。然而,诊断DR是一个具有挑战性的问题,需要有经验的眼科医生的服务。使用自动分类器,基于人工智能的深度学习可以帮助眼科医生提供与DR评估相关的专家建议。DR分类需要大量的数据来有效训练模型,这是DR领域的主要制约因素。迁移学习是一种可以帮助克服图像限制的方法。迁移学习方法背后的核心思想是,该框架已经在大量图像上进行了训练,这些图像可以进行微调以适应所需的数据集。本文将基于迁移学习的VGG16和InceptionV3模型应用于公共基准IDRiD数据集(印度糖尿病视网膜病变图像数据集)的DR分类。这些模型用于解决问题并最大化结果。

Torque Ripple Reduction in Six-phase Induction Motor Drive using DTC Technique 直接转矩控制技术在六相感应电动机驱动中的转矩脉动抑制

This work presents a Direct Torque Control (DTC) technique for a six-phase asymmetrical induction motor fed with a two-level six-phase inverter for torque ripple minimization. By increasing the levels in conventional torque hysteresis controller, high torque ripples (which is a major problem in basic DTC) can be minimized and dynamic torque response can be improved. But in practice, the inevitable delay existing in the implementation of hysteresis controllers will cause undesirable overshoot and undershoot in the torque response resulting in high ripples. Also, the torque decreasing rate is comparatively higher than that of torque increase which further boosts the torque ripples and degrades the steady-state performance. A five-level torque controller with modified output status is presented here by taking into account the above two limitations. The auxiliary subspace which is inherently present in a six-phase machine causing stator current distortion is also controlled by generating virtual voltage vectors. The resulting DTC drive is validated using MATLAB/Simulink software.
本文提出了一种用于六相非对称异步电动机的直接转矩控制(DTC)技术,该技术采用双电平六相逆变器来实现转矩脉动最小化。通过提高传统转矩滞后控制器的水平,可以最大限度地减少高转矩波动(这是基本直接转矩控制的主要问题),并改善动态转矩响应。但在实际应用中,迟滞控制器实施过程中不可避免的延迟会导致转矩响应的超调和欠调,从而产生高波纹。同时,转矩减少率高于转矩增增率,进一步加剧了转矩脉动,降低了稳态性能。考虑到上述两个限制,本文提出了一种具有修改输出状态的五级转矩控制器。通过产生虚电压矢量来控制六相电机中固有的引起定子电流畸变的辅助子空间。使用MATLAB/Simulink软件对所得到的DTC驱动器进行了验证。
