Integration of SmartParks in a Power System with Utility-Scale PV Plant

Abstract

This paper demonstrates integration of aggregate Plug-in Electric Vehicle parking lots known as SmartParks, adjacent to a MW-scale Photovoltaic (PV) plant for mitigation of loading on synchronous generators during peak hours as well as enhancing the Available Transfer Capability of area tie-lines. Simulations are carried out in the real-time digital simulator, where the PV plant and aggregate SmartParks are connected to a benchmark two-area multi-machine power system, equipped with secondary frequency controllers i.e. Automatic Generation Controllers and benefiting from Phasor Measurement Units data. The results conclude that cost-effective energy storage technologies such as SmartParks bring the potential in coping with one of the open challenges impeding PV penetration growth.
