Abstract: In this paper, a new Improved Bees Algorithm (IBA) is proposed for solving reactive power dispatch problem. The aim of this paper is to utilize an optimization algorithm called the improved Bees Algorithm, inspired from the natural foraging behaviour of honey bees, to solve the reactive power dispatch problem. The IBA algorithm executes both an exploitative neighbourhood search combined with arbitrary explorative search. The proposed Improved Imperialist Competitive Algorithm (IBA) algorithm has been tested on standard IEEE 57 bus test system and simulation results show clearly the high-quality performance of the projected algorithm in reducing the real power loss.

Abstract:Electricity is the world's fastest-growing form of end-use energy consumption. Net electricity generation worldwide will rise by 2.3 percent per year on average till 2035. Renewables are the fastest growing source of new electricity generation. Indian Solar PV Market enjoys its Place in the solar applications following the Infusion of tracking requirements. This paper focuses on the comparative study of maximum power point tracking (MPPT) techniques. It has been analysed with different MPPT methods following the same goal of maximizing the PV system output power by tracking the maximum power on every operating condition. In this paper maximum power point tracking techniques are reviewed on basis of simplicity, convergence speed, digital or analogical implementation, sensors required, cost, range of effectiveness, and in other aspects.

Keywords: MPPT, Tracking techniques, Convergence speed, Digital or analogical implementation.

Abstract: This paper presents hybrid particle swarm algorithm for solving the multi-objective reactive power dispatch problem. Modal analysis of the system is used for static voltage stability assessment. Loss minimization and maximization of voltage stability margin are taken as the objectives. Generator terminal voltages, reactive power generation of the capacitor banks and tap changing transformer setting are taken as the optimization variables. Evolutionary algorithm and Swarm Intelligence algorithm (EA, SI), a part of Bio inspired optimization algorithm, have been widely used to solve numerous optimization problem in various science and engineering domains. In this paper, a framework of hybrid particle swarm optimization algorithm, called Hybrid quantum genetic particle swarm optimization (HQGPSO), is proposed by reasonably combining the Q-bit evolutionary search of quantum particle swarm optimization (QPSO) algorithm and binary bit evolutionary search of genetic particle swarm optimization (GPSO) in order to achieve better optimization performances. The proposed HQGPSO also can be viewed as a kind of hybridization of micro-space based search and macro-space based search, which enriches the searching behavior to enhance and balance the exploration and exploitation abilities in the whole searching space. In order to evaluate the proposed algorithm, it has been tested on IEEE 30 bus system and compared to other algorithms.

Abstract:In this paper, we have suggested the spatial domain method for the digital video watermarking for both visible and invisible watermarks. The methods are used for the copyright protection as well as proof of ownership. In this paper we first extracted the frames from the video and then used spatial domain characteristics of the frames where we directly worked on the pixel value of the frame according to the watermark and calculated different parameters.

Abstract:In industrial control systems the liquid level is carrying its significance as the control action for level control in tanks containing different chemicals or mixtures is essential for further control linking set points. In this paper we will investigate the effect of PI and I controllers on a four tank process and will compare this controllers together. We want to know how much is the effect of, I and PI controllers on a process control. For more clarification we simulate the effect of PI and I controllers on this system.
