Asset optimization with effective design and evaluation of Solar and Wind hybrid system: Technology for reliable grid operation with large renewable penetration

Abstract

The ever-increasing load demand and the raising global environmental concerns worldwide have created in increased interest in clean and sustainable renewable energy sources. Among all the renewable sources wind and solar energy are the two major sources that have great potential. One of the key advantages of wind and solar sources is their complementary nature. Due to this complementary nature, these sources make an effective combination to create a PV/Wind hybrid energy system. The optimal design of the renewable energy system can significantly improve the economic and technical performance of power supply. In this paper, the technical-economic optimization study of a Solar Wind Hybrid System (SWHS) in NTPC Kudgi plant in Bijapur Karnataka is presented. The primary objective of this study is to estimate the appropriate placement of solar and wind, appropriate technology and effective sizing of evacuation system of SWHS that guarantee the energy autonomy of a typical load profile with lowest levelized cost of Electricity (LCOE). The results indicate that the hybrid system is the best option for the site which gives maximum yield from a piece of land and also provide grid stability and other benefits.
