Synchronous Condenser Configuration Method for Power Grid Voltage Support Strength Improvement
With the integration of large-scale renewable energy, the weak support of renewable energy power generation equipment makes the grid voltage support strength difficult to meet the needs of safe and stable operation. By configuring synchronous condensers, the voltage strength of the power grid can be effectively increased, but in power transmission channel planning and building, there is a lack of feasible synchronous condenser configuration methods. Based on the evaluation effect of multiple renewable energy stations short circuit ratio (MRSCR) on grid voltage support strength, considering the the limits of curtailment rate, this paper proposed a distributed hybrid optimal configuration method based on the quantitative index of grid voltage support strength. This method can significantly increase the grid voltage support strength after the renewable energy is connected by configuring synchronous condensers with a smaller total capacity. Combined with the calculation results of full electromagnetic simulation and electromechanical transient simulation of typical examples, it can be seen that the synchronous condenser configuration method proposed in this paper can effectively increase the grid voltage support strength and ensure the curtailment rate of the renewable energy transmission channel meeting the need of national requirement.
