Advanced Metering Infrastructure (AMI) is an important subsystem within the smart grid. Smart meters (SMs) in AMI play crucial role in establishing communication with outside world such as utility servers. They report real time power consumption data which aids in demand side management. Security of this link is an indispensable for cybersecurity. Authentication between SMs and utility servers is of prime importance for secure transmission of metering data, yet it increases the computational burden on operations. This paper proposes a light-weight Elliptic Curve Digital Signature Algorithm (ECDSA) certificate based authentication mechanism by utilizing different elliptic curves. Furthermore, computational times of authentication scheme with different ECDSA curves were compared with RSA digital signature algorithm. For this purpose, algorithms have been implemented using openSSL library. Results show that ECDSA authentication scheme has much better timing performance when compared to RSA; and can be safely used for authentication in AMI communication systems.
高级计量基础设施(AMI)是智能电网中的一个重要子系统。AMI中的智能电表(SMs)在与外部世界(如公用事业服务器)建立通信方面起着至关重要的作用。他们报告实时的电力消耗数据,这有助于需求侧管理。这一环节的安全是网络安全不可或缺的一部分。SMs和公用事业服务器之间的身份验证对于计量数据的安全传输至关重要,但它增加了操作的计算负担。本文利用不同的椭圆曲线,提出了一种基于证书的轻量级椭圆曲线数字签名算法(ECDSA)认证机制。此外,还比较了不同ECDSA曲线认证方案与RSA数字签名算法的计算次数。为此,使用openSSL库实现了算法。结果表明,与RSA相比,ECDSA认证方案具有更好的定时性能;并且可以安全地用于AMI通信系统中的身份验证。

As recent devices are growing in potentiality and accessibility, they offer more necessities in terms of security. With the extensively documented inadequate use of PINs, Continuous Authentication System (CAS) is constructed to overcome the vital issue of secure authentication and usability through biometric-based techniques to seamlessly authenticate the user identity. This work presents a multimodal biometric approach which includes the user information from iris and face. Human face and iris involve rich textural data that is the decisive information for biometric verification. It is very unique and one amongst the foremost precise biometric modalities. However, spoofing methods can be used to imitate or occult user identities and increase the possibility of FRR or FAR. Mostly, the print attack is employed as the impersonate user identities. It is noticed that print attack, independently and in conjunction, can crucially vary the interpersonal and intrapersonal distributions and thus improve the possibility to deceive the CAS. The system is assessed to investigate the performance of providing security and usability. The final outcomes illustrated that the system is capable to supply a 92% lessening in the number of invasive authentication requests needed for high-security applications.
随着最近的设备在潜力和可访问性方面的增长,它们在安全性方面提供了更多的必需品。随着广泛记录的pin使用不足,持续认证系统(CAS)的构建是为了克服安全认证和可用性的重要问题,通过基于生物特征的技术来无缝地验证用户身份。这项工作提出了一种多模态生物识别方法,其中包括来自虹膜和面部的用户信息。人脸和虹膜包含丰富的纹理数据,是生物识别验证的决定性信息。它是非常独特的,也是最精确的生物识别模式之一。然而,欺骗方法可以用来模仿或隐藏用户身份,增加FRR或FAR的可能性。大多数情况下,打印攻击是用来冒充用户身份的。值得注意的是,打印攻击,无论是独立的还是联合的,都可以极大地改变人际和内部的分布,从而提高欺骗CAS的可能性。对系统进行评估,以调查其提供安全性和可用性的性能。最终结果表明,该系统能够将高安全性应用程序所需的侵入性身份验证请求数量减少92%。

The proposed work intends to design a single channel boost power factor correction (PFC) AC to DC converter for wide range of power applications. Unlike the traditional approaches of PFC this topology manages to eliminate the ripple in input as well as in output current and voltage waveforms, reduces peak current and switching losses. Conventional controllers cannot obtain a good current shaping because of non-linear characteristics of converter at light loads and inaccurate average current samples in DCM mode. This inappropriate current profile also causes poor efficiency. A new digital hybrid control scheme which includes the sampling correction during reference current generation is employed for shaping the good input current in both CCM/DCM mode and also allows the smooth transition between two modes as the load changes. The proposed scheme also improves the reference current tracking at low load conditions. A satisfactory performance of 1KW PFC converter working at 50 KHz switching frequency with hybrid CCM/DCM control scheme is validated by simulation results at various load conditions. The obtained results of power indices comply with IEEE 519-1992 and IEC 61000-3-2 standards.
提出的工作旨在设计一种单通道升压功率因数校正(PFC)交流到直流转换器,用于广泛的功率应用。与传统的PFC方法不同,该拓扑设法消除了输入以及输出电流和电压波形中的纹波,降低了峰值电流和开关损耗。由于变换器在轻载时的非线性特性和DCM模式下平均电流采样不准确,传统的控制器无法获得良好的电流整形。这种不适当的电流分布也会导致效率低下。采用了一种新的数字混合控制方案,该方案包括参考电流产生时的采样校正,用于在CCM/DCM模式下塑造良好的输入电流,并允许在负载变化时在两种模式之间平滑过渡。该方案还改善了低负载条件下的参考电流跟踪。在各种负载条件下的仿真结果验证了采用CCM/DCM混合控制方案的开关频率为50 KHz的1KW PFC变换器的良好性能。所得功率指标符合IEEE 519-1992和IEC 61000-3-2标准。

The output power of solar photovoltaic modules at uniform irradiance are more as compared to non-uniform irradiance due to partial shading caused by passing clouds, the shadow of nearby buildings, dust etc,. The effect of partial shading, reduces the performance of PV system by minimizing output power and also its creates hotspots in the shaded PV modules that can damage the PV cells in solar PV modules connected in that PV array. To enhance the maximum output power of PV arrays under different partial shading cases with reconfiguration methods by interconnection of PV modules in different topologies, these are solar PV configurations or topologies. The main objective of this paper is modeling of different 4x4 size solar PV array topologies mainly Total-Cross-Tied, Series-Parallel, Honey-Comb and Bridge-Linked types under different partial shading cases and discuss the power loss analysis of these PV topologies. For this analysis, total 12 shading cases are considered and compare the power loss with one unshaded case. The parameters of LG Electronics LG215P1W PV module are considered for modeling and simulation of different types of topologies for a 4x4 size PV array in MATLAB/Simulink. Keywords- Solar PV output power, Power enhancement, solar Irradiances, PV modules, PV array configurations, Partial shading effect, power losses.
均匀辐照度下的太阳能光伏组件的输出功率要大于非均匀辐照度下的输出功率,因为通过的云层、附近建筑物的阴影、灰尘等会造成部分遮阳。部分遮阳的影响通过最小化输出功率来降低光伏系统的性能,并且在遮阳的光伏组件中产生热点,从而损坏光伏阵列中连接的太阳能光伏组件中的光伏电池。通过不同拓扑结构的光伏组件互连,通过重构方法提高不同部分遮阳情况下光伏阵列的最大输出功率,这些是太阳能光伏配置或拓扑。本文的主要目的是在不同的部分遮阳情况下,对不同4x4尺寸的太阳能光伏阵列拓扑进行建模,主要是全交系、串并联、蜂窝式和桥联式,并讨论这些光伏拓扑的功率损耗分析。在这个分析中,总共考虑了12个遮阳的情况,并将功率损失与一个未遮阳的情况进行比较。考虑LG电子LG215P1W光伏模块的参数,在MATLAB/Simulink中对4x4尺寸光伏阵列的不同类型拓扑进行建模和仿真。关键词:太阳能光伏输出功率,功率增强,太阳辐照度,光伏组件,光伏阵列配置,部分遮阳效应,功率损耗

Today’s emerging trends in the applications of wearable healthcare devices integrated with clouds and cloudlets technologies which strengthen the delivery of cost effective and high quality healthcare services. The Internet of Things (IoT), wearable devices, medical devices and healthcare systems provides the facilities to health care centers and doctors to monitor patient’s health at their homes using patient’s health data which is stored on cloud. Public area network is used to send data to cloud from healthcare devices, which is not secure. Opponent could read and change the data in the network during transmission. However, due to the heterogeneity, different characteristics and small size of smart wearable devices, specific method for the data protection with wearable device has not been yet established. Therefore to protect the privacy of patient’s data it needed access control mechanism based on encryption and cryptography. In this article, we review the different models, schemes as well as implementation related to data encryption and cryptography algorithms proposed by different researchers to secure smart wearable medical health care devices. To prevent the unauthorized access and securing the wireless communication as well as protect device integrity and data confidentiality Cryptography is the best approach.
当今的新兴趋势是,可穿戴医疗保健设备的应用与云和cloudlets技术集成,这些技术可加强提供具有成本效益和高质量的医疗保健服务。物联网(IoT)、可穿戴设备、医疗设备和医疗保健系统为医疗保健中心和医生提供了使用存储在云上的患者健康数据在家中监测患者健康状况的设施。公共局域网用于将数据从医疗保健设备发送到云,这是不安全的。对手可以在传输过程中读取和修改网络中的数据。然而,由于智能可穿戴设备具有异构性、不同特性和体积小等特点,目前还没有建立起针对可穿戴设备数据保护的具体方法。因此,为了保护患者数据的隐私,需要基于加密和密码学的访问控制机制。在本文中,我们回顾了不同研究人员提出的不同模型、方案以及与数据加密和加密算法相关的实现,以确保智能可穿戴医疗保健设备的安全。为了防止未经授权的访问和保护无线通信,以及保护设备的完整性和数据的机密性,加密是最好的方法。

This paper presents, the SSR characteristic analysis of the system with combined active and passive series compensation methods to increase secure loading, stability and fast control of power in the transmission line. The hybrid compensation is done by considering SSSC (an active FACTS device) and fixed series capacitor (passive compensation) method. Also, the Flower Pollination Algorithm is adopted in designing of the SSSC with Type-1 controller based on the damping torque analysis. The SSR analysis is carried out using damping torque, eigenvalue and transient simulation methods which show the effectiveness of SSSC in the elimination of torsional interaction at the operating point. The SSSC with Type-1 controller shows better performance in reducing the network resonant frequency along with improved power transfer capability of line.

Load Compensation using DSTATCOM 使用DSTATCOM进行负载补偿
Pub Date : 2019-03-01 DOI: 10.1109/i-PACT44901.2019.8960046
R. Venkateswari, S. Sreejith
This paper investigates the performance of DSTAT-COM as a load compensator. It is employed to mitigate the sag on load side. The sag is mainly due to the increase in the usage of the non-linear loads by the consumers. The DSTATCOM regulates the bus voltage by absorbing or generating reactive power. Depending on the system voltage, the DSTATCOM works on inductive or capacitive mode. In this paper, the analysis on the distribution side issues is performed with DSTATCOM compensation.
