Abstract
At present, the voltage support capability of receiving-end power grid is decreasing, so it is urgent to optimize the dynamic reactive power configuration for the security of the transient voltage of the system. Firstly, the generation method for the scene and fault set of the receiving-end power grid for STATCOM configuration is provided. Secondly, a sensitivity index based on the transient voltage severity is constructed to optimize the location of the STATCOM. Thirdly, a capacity optimization model with configuration cost as the objective function and considering transient voltage stability constraints is constructed. Then, the optimal configuration scheme is obtained by using particle swarm optimization algorithm. Finally, through the simulation calculation of STATCOM optimization configuration of Guangdong power grid, the results show that the proposed method is effective.
