STATCOM with braking resistor [12] or battery energy storage system (BESS) [13] have also been proposed for the stability enhancement of a large wind farm. To have short-term active and reactive power exchange ability during disturbance, power electronics based energy capacitor system (ECS) has also been proposed recently [14], [15].
Capacitor
Electronic symbol. In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone.

Energy Stored on a Capacitor
The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is ...
