This paper presents the use of multi-line flexible alternating current transmission systems (FACTS) device which is interline power flow controller(IPFC) for power system security enhancement by reducing number of overloaded lines and voltage violation buses. The security constrained optimal power flow (SCOPF) problem with IPFC is solved using proposed algorithm known as intelligent search evolution algorithm (ISEA). In the proposed algorithm, a two step initialization process have been adopted, the mutation operation is not used and also it gives optimal solution with less number of generations which results in the reduction of the computation time. Numerical results are carried out on a standard IEEE 14-bus system to demonstrate the effectiveness of proposed algorithm with IPFC.

In this paper a high performance improved three-phase power converter in modular approach for telecom power systems is proposed. The proposed system is formed by three single-phase modules with series connected dc outputs. The series connection of converter yields balanced dc link currents and galvanic isolation with the use of a high frequency transformer. Further it also and provides 6-pulse rectification, both together resulting in a small output filter components. The design methodology of the proposed converter is illustrated with an example. The design concepts are verified by the digital simulation of the proposed converter.

This paper presents the decoupled power control for a DFIG (doubly-fed induction generator) system using PI Control and FeedBack Linearization Control (FBLC). Further the controller performances are verified for the parameter variation also. Using the parameters of the laboratory machine, simulations are carried out to verify the effectiveness of the two control schems viz., PI and FBLC in the MATLAB Simulink. Based on the simulation results it is found that the FBLC performs better than PI for the decoupled control of DFIG.

LED based Solar Lanterns have evolved as a promising alternative to conventional rural lighting solutions. However, with the commencement of several Solar Lighting programs and the wide variety of products being introduced in the market, there is a lack of data characterizing the quality and performance of this wide range of products. This affects their long term, reliable performance towards ensuring sustainability, cost-effectiveness and user acceptance within the rural community. This paper proposes a `laboratory and field based integrated approach' leading to a holistic assessment of the technological gaps in the evaluation and dissemination chain of LED based Solar Lanterns. Basic laboratory tests, comparative performance evaluation, capturing of field usage parameters and fault assessment were carried out for 6 models of solar lanterns disseminated in 8 villages in India. Incorporation of additional features, design enhancements as well as improvements in systematic laboratory based evaluation mechanism have also been recommended in the paper. The findings are potentially applicable to the development of comprehensive benchmarks for performance specifications of LED solar lanterns, effective designing of such products for rural areas and ultimately resulting in greater impact of the several Solar Lighting programs on the rural society.

This paper proposes a maximum power point tracking scheme using neural networks for a grid connected photovoltaic system. The system is composed of a photovoltaic array, a boost converter, a three phase inverter and grid. The neural network proposed can predict the required terminal voltage of the array in order to obtain maximum power. The duty cycle is calculated and the boost converter switches are controlled. Hysteresis current technique is applied on the three phase inverter so that the output voltage of the converter remains constant at any required set point. The complete system is simulated using MATLAB/SIMULINK software under sudden weather conditions changes. Results show accurate and fast response of the converter and inverter control and which leads to fast maximum power point tracking.

An interval type-2 fuzzy logic controller (IT2FLC) is proposed in this paper for the design of power system stabilizer (PSS) applied for both single machine infinite bus (SMIB) and multi machine system incorporated with an AC1A exciter. For controller design, membership functions of system variables are represented using interval value fuzzy sets. Fuzzy logic based on interval value sets is capable of modeling the uncertainty and imprecision in a better way. The proposed controller performance is compared with the optimal lead lag and optimal type-1 fuzzy logic controller respectively reference to damp the oscillations of the system. Simulation results show not only the improve performance of the proposed controller but also it is robust with respect to system parameter variations and applied disturbances. This electronic document is a “live” template. The various components of your paper [title, text, heads, etc.] are already defined on the style sheet, as illustrated by the portions given in this document.
