Chapter 30 - Optimal design and techno-socio-economic analysis of hybrid renewable system for gird-connected system

Abstract

In recent days the energy consumption is increasing very fast because of the extensive progress of modern linear and nonlinear loads within the industrial, residential, and commercial areas globally. In the context of smart microgrid, the high penetration of renewable sources offers technical and social benefits globally. Besides, the continuous growth of power consumption will affect the grid technical as well as economic performances. Due to said reason reduction in the quality of power, reliability, voltage stability and also increase in losses, harmonics and cost of energy are replicate in the grid. Therefore the effective control, analysis, and management of all these problems in the system are essential for reliable and accurate operation. In the proposed work, a case study of NIT Durgapur grid=connected system with photovoltaic, wind and battery-based hybrid renewable energy generation system is considered. Integration of renewable energy sources into the grid shows a considerable impact on distribution system performances, such as cost economy, losses, stability, reliability, pollutant emissions, and other technical social and economic parameters. In this work, the HOMER-grid and MATLAB software are utilized as simulation and optimization tools to perform the social, economic, and technical suitability of the proposed case study for hybrid renewable energy system (HRES). The best solution of presented hybrid renewable system is decided based on the minimization of cost of energy and net present cost with simultaneous decision of higher feasibility and reliability. Subsequently, the comparative analysis of the technical, social/environmental, and economic parameters for the proposed HRES is presented, showing that the overall performances of system are enhanced as compared to the base system of case study.
