An Overview on Structural Advancements in Conventional Power System with Renewable Energy Integration and Role of Smart Grids in Future Power Corridors

Abstract

Renewable energy (RE) sources are gaining popularity in mainstream power system. A conventional vertical power system is being seen as in need of modification to meet the strong requirements of uninterruptible power, growing consumption of electricity in rural and urban areas, mitigating voltage fluctuation problems for far-end loads and overall cost reduction of erecting huge long power transmission networks for feeding remote areas. The concept of one-way power transmission is slowly being replaced in renewable energy sources connected to power system. The renewable energy sources are generally low inertia small machines, driven by renewable sources like solar, water, hydro and waves. These are preferred to be connected near to load points to fulfill local load demands. Nowadays, the power system is a distributed network energy system, with several renewable energy sources along with communication and automatic control, in practice. In this chapter, the evolution of modern power system, various renewable energy sources and their interconnection in the proposed future power system is discussed with schematic diagrams.
