PV module integration with STATCOM for reactive power compensation 光伏模块集成STATCOM无功补偿
K. Tharani, R. Dahiya
Generation and Transmission of power is a complex process, which requires the working of many components of the power system so as to deliver the maximum power output. We need to manage the flow of Active and Reactive power in an efficient and economic way so as to improvise the performance of power systems. Thus, a Static synchronous compensator (STATCOM) integrated with Photovoltaic (PV) module can be used to optimize the reactive power flow by varying the level of voltage for the Voltage Source Converter with respect to source bus voltage. By connecting PV modules directly to STATCOM, the requirement of DC-DC Converter can be completely overcome as STATCOM regulates DC voltage at optimal value. In the present integrated study system using PV and STATCOM simulated in Simulink software, the effect of varying solar irradiance and changing the number of solar cell modules on the reactive power have been studied.
电力的产生和输送是一个复杂的过程,需要电力系统的许多部件共同工作,才能提供最大的功率输出。我们需要对有功和无功功率的流动进行有效和经济的管理,以提高电力系统的性能。因此,与光伏(PV)模块集成的静态同步补偿器(STATCOM)可以通过改变电压源变换器相对于源母线电压的电压水平来优化无功潮流。通过将光伏组件直接连接到STATCOM,可以完全克服DC-DC转换器的要求,因为STATCOM可以将直流电压调节到最优值。本文在Simulink软件中模拟了PV和STATCOM的集成研究系统,研究了不同太阳辐照度和不同太阳能电池组件数量对无功功率的影响。

Outlier detection: A survey on techniques of WSNs involving event and error based outliers 异常点检测:基于事件异常点和误差异常点的无线传感器网络技术综述
D. Shukla, A. Pandey, Ankur Kulhari
In the recent few years, many wireless sensor networks have been distributed systematically in the real world to collect valuable raw sensed data. However, the crucial point of challenge is to extract high level knowledge from this raw sensed data. In the application of data analysis, a necessary preprocessing step is anomaly detection, also known as deviation detection or data cleansing. Outliers in wireless sensor networks (WSNs) are those measures that deviate from a defined pattern. Outlier detection can be used to remove noisy data, detect faulty nodes and discover interesting events. Numerous small and low cost nodes loaded with capabilities of integrated sensing and computation are involved in a WSN structure. Due to high density WSNs are exposed to faults and nasty attacks causing inaccurate and unreliable sensors reading, making Wireless sensor networks prone to outliers. This survey provides an outline of outlier detection techniques and approaches focusing on event and error based outliers.
近年来,许多无线传感器网络已经系统地分布在现实世界中,以收集有价值的原始传感数据。然而,关键的挑战在于如何从这些原始的感知数据中提取高层次的知识。在数据分析的应用中,一个必要的预处理步骤是异常检测,也称为偏差检测或数据清洗。在无线传感器网络(WSNs)中,异常值是指那些偏离定义模式的测量值。异常值检测可用于去除噪声数据,检测故障节点和发现有趣的事件。WSN结构中包含许多具有集成传感和计算能力的小节点和低成本节点。由于高密度的传感器网络容易受到故障和恶意攻击,导致传感器读数不准确和不可靠,使无线传感器网络容易出现异常值。本调查提供了一个轮廓的异常点检测技术和方法,重点是基于事件和错误的异常点。

Unfolding various security brawls and concerns of cloud computing 展开云计算的各种安全争论和关注
Navdeep Singh, Abhinav Hans, Ashish Sharma, Kapil Kumar
The cloud computing is a discreet system which provides a lade system for the users in which a user can surf the online software facility. The cloud system is considered as the hosted service in which a particular user can access the cloud system remotely by using mobile applications or by using the browsers. Though the cloud computing provides so many utilities but there are also some holes in the service. Amongst all the security issues of the service come on the top. The security is the most important thing whenever you design any hardware or software. If the system is not secure then it will not be worth to use it. So this paper is emphasising on some security issues and their solutions to make the cloud system better.

NONACK in wireless ad hoc network 无线自组网中的NONACK
Trisha Mittal, B. Kumar
A wireless ad hoc sensor network (WSN) is made up of a number of geographically spread apart sensors each with a reasonable amount of signal processing and data networking ability coupled with wireless communication. One of the major challenges wireless sensor networks face today is security. Denial of service (DoS) attack is meant not only for the adversary's attempt to subvert, disrupt, or destroy a network, but also for any event that diminishes a network's capability to provide a service. This paper explores resource depletion attack in a cooperative manner and increasing traffic on the routing layer protocol. The ease of carrying out a NONACK (Noose Noose attack) and the difficulty in its detection makes all examined protocols very susceptible to it. The worst case scenarios can see an upsurge in the network-wide usage by a factor of O(N2), N being the number of network nodes.
无线自组织传感器网络(WSN)由多个地理位置分散的传感器组成,每个传感器具有合理数量的信号处理和数据网络能力,并具有无线通信能力。当今无线传感器网络面临的主要挑战之一是安全性。拒绝服务(DoS)攻击不仅意味着对手试图颠覆、破坏或摧毁网络,而且还意味着任何削弱网络提供服务能力的事件。本文探讨了在路由层协议上采用协作方式和增加流量的资源耗尽攻击。执行NONACK(套索攻击)的便便性和其检测的难度使得所有被检查的协议都非常容易受到它的影响。在最坏的情况下,整个网络的使用率会以0 (N2)的倍数激增,N是网络节点的数量。

A. Q. Ansari, Ibraheem, Sapna Katiyar
To achieve good performance from the system, performance index plays vital role in the objective function. In this paper various performance indices are used as the objective functions. The choice of the objective function is the most crucial and complicated step in applying any optimizing algorithm for an adaptive control system. They are used to evaluate fitness of items for iterations. The various objective functions like Mean of the Squared Error (MSE), Integral of Time multiplied by Absolute Error (ITAE), Integral of Absolute Magnitude of the Error (IAE), Integral of the Squared Error (ISE) and Integral of Time multiplied by the Squared Error (ITSE) have been analyzed and compared to find the most suitable one. Ant Colony Optimization algorithm is applied to tune a PID controller to find out best solution and to study the behavior of different performance indices.

M. Khan
In this paper, a simple voltage modulation technique is described for a quasi six-phase voltage source inverter (VSI). The proposed modulation is based on the sampled reference voltages and effective time concept. In the proposed technique the actual switching times for each inverter legs are obtained directly in simple form. The execution time in real time application can be reduced significantly compared to the conventional space vector pulse width modulation (SVPWM). Simulation and experimental results are provided to validate the proposed theory.
