Economic Integration of Renewable Energy Sources for Optimal Operation of Smart Grid

摘要

Integration of renewable energy sources (RES) into modern power networks is a difficult task for system operators considering their intermittency of generation, effect on the operating condition and ability to disorganize the daily operation of electric grid. This paper presents an efficient integration algorithm and methodology of solar and wind energy sources with modern power system to revamp the standard of electric power supply at minimum price and highest reliability in smart grid infrastructure. The costing characteristics of solar and wind unit have been modelled in this work suitably by the data collected from NASA Surface Metrology and Solar Energy to incorporate these clean energy sources into the optimal power flow programme (OPF) with a pareto optimal objective function substantiating the welfare of all the individual participants. In the presence of renewable energy sources, this methodology has been demonstrated to be able to sustain reliable and standard operating condition. The algorithm has been examined in IEEE 30-bus system to demonstrate its efficacy.
