Application of Crow Search Algorithm to solve Real Time Optimal Power Flow Problem 乌鸦搜索算法在实时最优潮流问题中的应用
P. Bamane
This paper presents the application of a metaheuristic optimization method called Crow Search Algorithm (CSA) to solve real time Optimal Power Flow (OPF) problem. CSA is the population based algorithm which mimics the behavior of food foraging process of crows. To show the effectiveness of the algorithm it is first applied to benchmark function. Optimal Power Flow is the power system optimization problem. The CSA algorithm is applied to solve Optimal Power Flow considering different source such as thermal, wind and solar. The IEEE 30 bus system is taken for consideration. The results obtained are compared with other algorithm for defined optimization problem as well as benchmark functions. The result shows that CSA gives best solution as compared other algorithms.

Sentiment Analysis On Product Review: A Survey 产品评论的情感分析:一项调查
M. Ezhilarasan, V. Govindasamy, V. Akila, K. Vadivelan
Online reviews are considered as one of the most essential sources of client opinion. In current scenario, consumers can learn about the products and services using online review resources to make decisions. The customer reviews for numerous products plays a very vital role not only for purchasers, But also for the firms. Consumer reviews are used by companies as feedback in their product development strategies and in the management of consumer relations. Due to their disorganized nature, consumer reviews with valuable information still face difficulties in navigating information. Driven by a need for profit, some organizations may generate spam reviews regarding different products or their own product which may mislead customers to buying unworthy product. Because of its promising commercial benefits, Sentiment Analysis has become one of the most interesting subjects in text analysis. One of its main problem is the detection of false negate reviews. In addition, the user reviews can be classified as positive or negative reviews so that a consumer can use the false review to select a product. In this paper, we examine various levels of Sentiment Analysis and compare different existing techniques.
在线评论被认为是客户意见最重要的来源之一。在当前的场景中,消费者可以使用在线评论资源来了解产品和服务,从而做出决策。消费者对众多产品的评价不仅对购买者,而且对企业都起着至关重要的作用。消费者评论被公司用作产品开发策略和管理消费者关系的反馈。由于有价值信息的消费者评论的无序性,它们在导航信息时仍然面临困难。在利润需求的驱使下,一些组织可能会对不同的产品或自己的产品产生垃圾评论,这可能会误导客户购买不值得的产品。情感分析由于具有良好的商业效益,已成为文本分析领域的研究热点之一。它的一个主要问题是检测假阴性评论。此外,用户评论可以分为正面或负面评论,以便消费者可以使用错误的评论来选择产品。在本文中,我们研究了不同层次的情感分析,并比较了不同的现有技术。

Resistive Capacitive Switching Technique for the Mitigation of Power Capacitor Switching Transients 缓解电力电容器开关瞬变的阻容开关技术
Yuvraj J Gaikwad, A. Thorat
This paper presents an elimination of transients during switching of power capacitor with resistive capacitive switching technique. During the power capacitor switching large spikes of voltage and current appears which exists for less time in the system. A magnitude of such spikes is much greater than that of the ordinary current and voltage in the steady state system. During the switching of capacitor bank such spikes will occurs which tends to damage the equipments and reduces the lifespan of capacitor banks. Therefore to mitigate these spikes from the system a resistive capacitive switching technique is used. In this paper resistive capacitive switching technique is implemented in MATLAB and switching spikes are eliminated.
本文提出了一种用阻容开关技术消除电力电容器开关过程中瞬态的方法。在功率电容器的开关过程中,会出现较大的电压和电流尖峰,且尖峰在系统中存在的时间较短。这种尖峰的幅度远远大于稳态系统中普通电流和电压的幅度。在电容器组的开关过程中,会产生尖峰,容易损坏设备,降低电容器组的使用寿命。因此,为了减轻系统中的这些尖峰,采用了阻容开关技术。本文在MATLAB中实现了阻容开关技术,消除了开关尖峰。

R. Devi, P. Vyshnavi, V. Devi
This paper introduces a topology which depends on flying capacitor (FC) model reasonable for staggered converters. The arranged topology utilizes the prospect of segment moved bearer beat width balance (PSC-PWM) with changed adjusting signs to create suitable PWM signals. The balance of the system along-side all conceivable exchanging stages are clarified. The outcome of the proposed PWM strategy is appeared with the help of representing waveforms. For demonstrating the upsides of the desired structure, a diverse execution criterion has been contrasted and other FCM (Flying Capacitor Multi cell) structures are included. Reenactment results are utilized to extra quantify the potential merits of the arranged system. It is said that the proposed arranged structure is better than other FCM based structures from various points of view. In particular, it diminishes the quantity of high recurrence switches, the quantity of flying capacitors, and in the meantime improves the characteristics of yield voltage. The research center sort exploratory setup is utilized to approve the adjustment procedure and other hypothetical discoveries.

An Improved GMPPT Technique Under Partial Shading Conditions for PV Array 光伏阵列部分遮阳条件下改进的GMPPT技术
Purva Nagvekar, R. Metri
PV solar is widely establishing technology which is considered as a promising source to replace the conventional technologies. But it has limited usage due to its limitations such as low efficiency, invariable nature etc. The efficiency of PV array is affected by one such factor that is called as partial shading condition. This partial shading condition is a state in which all the PV panels do not receive uniform irradiation and this leads to complex P-V characteristics. In such characteristics, there is only one global power peak and other are local power peaks. The presence of multiple peaks in partial shading condition on P-V curve make the conventional MPPT techniques such as Perturb and Observe, Incremental conductance etc ineffective. Thus, an improved global maximum power point tracking (GMPPT) technique is proposed which is used for detecting the global peak. This uses the hill climbing technique in modified form. This proposed technique will detect the global peak and thus will deliver maximum possible output during partial shading condition.
光伏太阳能是一种被广泛应用的技术,被认为是一种有希望取代传统技术的能源。但由于其效率低、性质不变性等局限性,其应用受到了限制。光伏阵列的效率受到其中一个因素的影响,即部分遮阳条件。这种部分遮阳条件是一种状态,在这种状态下,所有PV板都没有受到均匀的照射,这导致了复杂的P-V特性。在这种特性中,只有一个全局功率峰值,其他都是局部功率峰值。在部分遮阳条件下,P-V曲线上存在多峰现象,使得Perturb和Observe、Incremental conductivity等传统的MPPT技术失效。为此,提出了一种改进的全局最大功率点跟踪(GMPPT)技术,用于检测全局峰值。这是一种改良形式的爬山技术。这种提出的技术将检测全局峰值,从而在部分遮阳条件下提供最大可能的输出。
