Abstract

The random variation of wind speed causes active power and reactive power injection of large-scale wind base to fluctuate constantly, this in turn leads to voltage fluctuation and unqualified voltage amplitudes of this area. This article proposes quantitative voltage control to solve this problem. Firstly, analyze the reason and characteristic of voltage fluctuation in large-scale wind base. Then apply sensitivity method to derive voltage/reactive power sensitivity coefficient matrix; this matrix is the product of two special matrices, one is symmetric and the other is diagonal. It can be demonstrated that the symmetric one has a relatively bigger value at the diagonal line; combined with the diagonal one, several simple conclusions can be obtained. According to the conclusions, quantitative voltage control flow can be established. In addition, operating mode of wind turbine generator is taken into account in the simulation process. Simulation results of IEEE 9 nodes system and an actual system demonstrate the validity of proposed measures.
