Optimal Controller for Single Phase Island Photovoltaic Systems
Increasing of word demand load caused a new Distributed Generation (DG) to enter to powersystem. One of the most renewable energy is the Photovoltaic System. It is beneficial to use thissystem in both separately as well as connected to power system using power electronics interface.In this paper an optimal PID controller for Photovoltaic System systems has been developed. Theoptimization technique is applied to PID optimal controller in order to control the voltage ofPhotovoltaic System against load variation, is presents. Nonlinear characteristics of loadvariations as plant input, Photovoltaic System operational behavior demand for high qualityoptimal controller to ensure both stability and safe performance. Thus, Honey Bee MatingOptimization (HBMO) is used for optimal tuning of PID coefficients in order to enhance closedloop system performance. In order to use this algorithm, at first, problem is written as anoptimization problem which includes the objective function and constraints, and then to achievethe most desirable controller, HBMO algorithm is applied to solve the problem. In this study, theproposed controller is applied to the closed loop photovoltaic system behavior. Simulation resultsare done for various loads in time domain, and the results show the efficiency of the proposedcontroller in contrast to the previous controllers.

Digital Watermarking Technology in Different Domains
Due to high speed computer networks, the use of digitally formatted data has increased many folds.The digital data can be duplicated and edited with great ease which has led to a need for effectivecopyright protection tools. Digital Watermarking is a technology of embedding watermark withintellectual property rights into images, videos, audios and other multimedia data by a certainalgorithm .Digital watermarking is a well-known technique used for copy rights protection ofmultimedia data. A number of watermarking techniques have been proposed in literature. DigitalWatermarking is the process that embeds data called a watermark into a multimedia object such thatwatermark can be detected or extracted later to make an assertion about the object. A variety oftechniques in different domains have been suggested by different authors to achieve above mentionedconflicting requirements. All the watermarking techniques are different from each other and are usedfor differing applications.

Load Frequency Control in Power Systems Using Improved Particle Swarm Optimization Algorithm
The purpose of load frequency control is to reduce transient oscillation frequencies than its nominal valueand achieve zero steady-state error for it.A common technique used in real applications is to use theproportional integral controller (PI). But this controller has a longer settling time and a lot of Extramutation in output response of system so it required that the parameters be adjusted as appropriate . In thispaper, we aim to design a system based on PI controllers using improved particle swarm optimizationalgorithm for load frequency control .Multi-population approach and local search to improve theoptimization algorithms is used and displayed. That this approach will lead to accelerating the achievementof results, preventing entrapment in a local minimum, and get better system output compared with similarmethods.

FPGA Can be Implemented Using Advanced Encryption Standard Algorithm
This paper mainly focused on implementation of AES encryption and decryption standard AES-128. All the transformations of both Encryption and Decryption are simulated using an iterativedesign approach in order to minimize the hardware consumption. This method can make it avery low-complex architecture, especially in saving the hardware resource in implementing theAES InverseSub Bytes module and Inverse Mix columns module. As the S -box is implemented bylook-up-table in this design, the chip area and power can still be optimized. The new MixColumn transformation improves the performance of the inverse cipher and also reduces thecomplexity of the system that supports the inverse cipher. As a result this transformation hasrelatively low relevant diffusion power .This allows for scaling of the architecture towardsvulnerable portable and cost-sensitive communications devices in consumer and militaryapplications.

Sliding-Mode Control of the DC-DC Ćuk Converter in Discontinuous Conduction Mode
In this paper, a novel approach for two-loop control of the DC-DC Ćuk converter in discontinuousconduction mode is presented using a sliding mode controller. The proposed controller can regulatethe output of the converter in a wide range of input voltage and load resistance. Controllerparameters are selected using PSO algorithms. In order to verify the accuracy and efficiency of thedeveloped sliding mode controller, the proposed method is simulated in MATLAB/Simulink. It isshown that the developed controller has, the faster dynamic response compared with standardintegrated circuit (MIC38C42-5) based regulators.

Efficient Short-Term Electricity Load Forecasting Using Recurrent Neural Networks
Short term load forecasting (STLF) plays an important role in the economic and reliable operation ofpower systems. Electric load demand has a complex profile with many multivariable and nonlineardependencies. In this study, recurrent neural network (RNN) architecture is presented for STLF. Theproposed model is capable of forecasting next 24-hour load profile. The main feature in this networkis internal feedback to highlight the effect of past load data for efficient load forecasting results.Testing results on the three year demand profile shows higher performance with respect to commonfeed forward back propagation architecture.
