摘要：In modern power system, plugged in electric vehicle plays a very vital role inregulation of system frequency as it is a form of battery energy storage system. This paperpresents an aggregate model consisting of a three area system embedded with electricvehicle (EV) in all the three control areas along with Dish-Stirling solar thermal system(DSTS) in only Area-1. The thermal systems are provided with single reheat turbine,governor dead band and generation rate constraint of 3% per minute to give a more realisticview to the designed system. Two degree of freedom Proportional-Integral-Derivative(2DOF-PID) controller with filter is applied as secondary controller in all the three controlareas. Maiden application of a new nature inspired optimization technique called WindDriven Optimization technique in load frequency control is made in this paper. Acomparison is done between 2DOF-PID and Proportional-Integral-Derivative (PID)controller to verify the effectiveness of the former. Analysis reveals the advantage ofincluding DSTS in the aggregate model which proves the role of renewable energy sourcesin overcoming the fluctuations in frequency and tie-line power in a power system underboth nominal 1% step load perturbation and random load perturbation. An attempt has alsobeen made to show the impact of incorporating EVs under nominal system condition intothe system, and it has been observed that the number and magnitude of oscillations aredecreased to great extent with its incorporation.
