Techno-economic assessment and environmental analysis of an optimal hybrid system under novel demand response scheme for a remote region of India

Abstract

This paper presents a novel framework of demand response (DR) scheme in order to get the optimum design and operation of Solar PV/Diesel Generator/Grid based hybrid system. Hybrid system economic model has been developed incorporating different decision variables of each system component. Further, a shifting based DR scheme is proposed in the paper to reduce the peak load demand of a remote region of India. HOMER software is used to simulate and optimization of hybrid system with and without shifting based DR scheme. Furthermore, a comparison of system sizes, economic metrics and environmental metrics has been made. It has been found that system economic parameters and system component sizes have been significantly reduced with DR. Amount of emissions generated from the system such carbon dioxide, carbon monoxide and nitrogen oxides are also reduced with DR. Finally, a sensitivity analysis of hybrid system has been performed for various system parameters to recognize the most sensitive parameter.
