Valsamma K.M · IOSR Journal of Engineering · 2012
Rural and Remote electrification is now-a day's an important market for renewable energy production and since the last decade, off-grid rural electrification with renewable energy sources has become a cost-effective option.This study presents an analysis for choosing the best hybrid Renewable Energy Technology system & estimates systematically the dynamics of electrical power generation from a mix of renewable energy, to satisfy the needs of the rural area Kuttumpuzha in India, using multi-scaling analysis.In order to demonstrate the capability of fractal approach on electrical power demand, we choose Wavelet Transform Modulus maxima (WTMM) technology and results imply that this method is powerful in studying the singularities of time series signals.We show that the WTMM, the so called multi-resolution analysis, can determine the singularity spectrum of multi-fractal measures from the scaling behavior of the partition function, and account for the multi-fractal nature of the time series obtained from the chaotic phenomena.Applying the WTMM we will be able to verify that the time series of micro grid incorporated with renewable energy resources is a persistent series and this method can be used to compare the quality of the process using different mix of renewable resources.The correlation dimensions found tells us that the series obtained is long-range correlated with long term memory.This lays that a hybrid renewable energy technology system with a combination of solar, & wind, energy system, converter, and batteries, for the rural village from the different perspective combinations for power generating system is cost effective even in areas where the grid connection would be possible and better suited to satisfy oscillations in the demands .
