Title
Stability of Fast Q(U) Voltage Droop Control of Wind Parks in High Voltage Distribution Grids
Abstract
In order to allow for the participation of wind parks in primary voltage control of the network, fast controller dynamics
are required in the order of one second. An appropriate type of voltage control is the droop control applying a Q(U)
characteristic. As the droop control is potentially oscillatory, it has to be designed carefully, considering system stability.
In order to identify the influence of controller characteristics on stability, a stability analysis has been carried out for
Q(U)-controlled wind parks. This paper presents the results and derives an analytic relation between stability and basic
parameters of the control system. Decentralised wind park control is proposed as an advantageous general structure for
fast control dynamics.
