Abstract

Future power networks will feature high penetration of renewable energy to mitigate global climate change. Due to reduced dispatchablility of generation based on variable renewable energy, the effectiveness of generation-side regulation is being degraded. In this context, regulation mechanisms that leverage the feasibility of network topology are expected to be more widely and actively engaged in operations of future power networks. This talk will give an overview of our recent works on topology optimization of power networks. Firstly, a set of linear connectedness constraints and a reduction scheme will be introduced. These constraints are compatible with existing optimal transmission switching models to ensure topology connectedness strictly, and the reduced version further improves computational efficiency. Secondly, some results on leveraging topological feasibility to improve synchronization performance of low-inertia power networks will be presented. A transmission switching approach has been developed here by analysing the sensitivity of synchronization performance to perturbation of network susceptance. Finally, a learning-based solution approach for topology optimization will be introduced. This approach is based on the identified common pattern behind existing heuristic algorithms and is capable of tackling some complicated cases of topology optimization efficiently.
