“The optimization of reactive power voltage coordination control in offshore wind farms faces the challenge of traditional methods relying on detailed parameters and time-consuming solutions. A Chinese research team proposes an optimization method based on an improved depth deterministic policy gradient, establishes a reactive power voltage coordination optimization operation model, transforms the multi constraint optimization problem into a Markov decision process, and uses iDDPG for solving. It has significant advantages in model solving accuracy and real-time response speed, providing a new solution for improving voltage stability in offshore wind farms.”
