01-Apr16 Improvement in power quality by Grid Interconnection of Renewable Energy Sources (Page No. 1-4)
AUTHORS : Nikita Kadwe , Rahul Gupta
ABSTRACT : Due to disperse nature of renewable energy resources (RES), electricity generation is often taking place in small scale but main drawback is power quality. So to improve power quality issues, integration of renewable energy into the utility grid can be done either at transmission level or the distribution level depending on the scale of generation. The renewable resources like solar energy, wind energy, fuel cells, biomass energy, etc. are interconnect using various power electronics converters. Generally voltage source inverters are used to interface the intermittent RES in distributed system.
This paper presents integration of solar energy and wind energy resources for distribution level using multi-level inverter and its control strategy to achieve the voltage profile of system. Usually, the photovoltaic energy sources generate power at variable low dc voltage, while the variable speed wind turbines generate power at variable ac voltage. Thus, the power generated from these renewable sources are interconnect using various converters before connecting on dc-link. The voltage source inverter is a key element of a distributed generation system as it interfaces the renewable energy source to the grid and delivers the generated power. This concept of interconnection of solar and wind energy is designed and simulated in MATLAB-Simulink for non-linear load.

02-Apr16 Design and Optimization technique for PV-Wind Hybrid Generation System Based on Fuzzy Logic Controller (Pg. no 5-10)
AUTHORS : Vikram Singh, Mr.Vivek Kumar Yadav, Mr. E .Vijay Kumar
Abstract — In this study, a new approach of optimum and Economical sizing of a Hybrid PV-Wind energy system is presenting in order to assist the Projector to take into contemplation, both of the economic and ecological aspects. This context presents the varied optimization techniques to circumvention the hybrid PV-wind Modal. The hybrid Modal implies the photovoltaic panels and wind turbines. Fuzzy logic Based Optimization techniques are employ to minimize the formulated substantial function, i.e. total cost which add the initial costs, yearly substitution cost, yearly labourer’s cost and sustenance costs with conduce value of the proposed hybrid Modal. It also exhibit the rehearsed and spectacle comparison between the modal with fuzzy and without fuzzy techniques for eminent sizing of spurious PV/Wind energy modal. One computer program and one Matlab model are designed, using MATLAB code to formulate the optimization issue by numerating the colligation of the objective task. Finally, the optimal annotation is achieved by fuzzy logic optimization method. Dynamic modelling, management and simulation have a glance at in the PV/wind electric technology system is dead in MATLAB/Simulink application. The simulation results obtained via various load things and precise analysis of this attached simulation model are given.
