 Combined Active and Reactive Power Compensation
Can we be more creative in using Electric Vehicles? Probably - some recent studies have shown that the power electronics AC-DC inverter circuits used for charging PEVs can potentially contribute in to reactive power compensation using appropriate P-Q control. 
The common solution to provide reactive power compensation is to install a combination of shunt capacitors, switchable capacitors, and static var compensators (SVCs) to be constantly adjusted according to the reactive power compensation needs of the wind DG unit. However, with the increasing penetration rate of wind power generation, the amount of reactive power to be compensated is growing. In most cases, such amount is a fluctuating stochastic variable. Since the response time for SVCs is relatively slow, engineers are investigating the use of static synchronous compensators (STATCOMs), which have faster response time. However, STATCOM devices are usually expensive and may not be a feasible solution for large-scale deployment of wind DG units.
Thus, our approach can be very promising!
