摘要：

A new reactive power control strategy is presented in this paper for voltage stability and improvement of low voltage ride through (LVRT) capability. Both rotor side converter (RSC) and grid side converter (GSC) are taken into account for the purpose of voltage stability and improvement of system's robustness. In this algorithm, the required reactive power is optimally managed at an individual point of common coupling (PCC) by using linear matrix inequality (LMI) technique. Jacobian matrix (JR) is also employed to have better accuracy and realize the required bound of injected reactive power. To minimize the system's conservative nature, dynamic couplings of the system are considered, unlike the existing methods. Results and simulations are discussed in more details to illustrate the effectiveness of the proposed method.
