Integrating Distributed Renewable Energy Sources into Smart Grids: A Comprehensive Analysis

This article gives a literature review of incorporating DRES into smart grids, and presents a novel more comprehensive investigation of the effects on the small signal stability of smart grids, economic aspects, and system performance. On the same note, it has been observed that as consumers continue to embrace DRES, there are benefits that come with this as well as challenges that come with it. Thus, our investigation for diverse integration approaches using simulation shows that DRES integration can improve the power system’s reliability and decrease fuel consumption, although they can destabilise the grid and so effective management schemes are needed. The findings show that while all major and minor investments are necessary for integration of DRES into electrical power systems at the first level, that beneficiary effects are significant in terms of costs and environmental impacts in the following long term. Frequency distributions using histograms and pie charts explored within the analysis offer valuable picture of the net benefits distribution and proportion of contribution from various types of renewable energy sources, which helps in understanding economic and operational implications. Consequently, the research highlights the need for more sophisticated methods of dealing with the spatial energy grid, including frequency regulation and demand response to cater for the fluctuating nature of renewable energy sources.
