A novel strategy for determination of optimal sizing of PV-wind hybrid system

Abstract

A novel methodology for strategic selection of different components of PV-wind hybrid system is presented here. The optimal sizing determination is a key factor for pre-feasibility and feasibility analysis of hybrid system for any specific site. The capacity of battery, diesel generator (DG) and converter is determined with this novel approach ensuring a low cost reliable system with zero load rejection. Here, instead of taking maximum value of surplus or deficit energy or predefined rated components for obtaining size of battery, DG and converter, a random number between minimum and maximum values are considered as the criteria for selection. A detailed flow chart describing the approach and operational energy flow is presented. The system total net present cost (TNPC) and levelized unit electricity cost (LUEC) are obtained of the optimal configuration of hybrid system yielding system feasibility and approach adoptability.
