Abstract

Power electronic-Based FACTS devices such as STATCOMs are sometimes essential for voltage support in transmission networks. They can also be used for continuous operation of doubly fed induction generator-Based wind turbines during faults. However, these devices are quite expensive and therefore cannot be used extensively. This paper explores the potential of a low-cost solution that utilizes the reactive power and voltage support capabilities of plug-in vehicles parked in charging stations (SmartParks) so that they can behave as virtual STATCOMs. for this solution, a 12-bus multimachine power system is considered wherein one of the conventional units is replaced by a 400 MW wind farm. Twelve SmartParks are developed and integrated into the test system. First, they are connected to a weak bus in the system and used in voltage control mode. their performance is compared with a STATCOM of a similar rating. Next, the SmartParks are connected to the wind farm bus, and a coordinated reactive power control strategy is proposed to improve the fault-ride-through capability of the wind farm without exceeding the current limits of rotor and grid-side converters. the entire study is carried out in real time on a real-time digital simulator platform. © 2011 IEEE.
