Expansion Planning of Transmission Network and B-SMES Considering Wind Power Penetration

This paper presents a joint expansion robust planning approach for transmission network and battery-superconducting magnetic hybrid energy storage system (B-SMES) under the typical scenario set of wind power and loads. A two-stage robust optimization model is established and solved iteratively based on Benders decomposition algorithm. The suggested model obtains the planning scheme combining economy and security under the accident states of the power system, which optimize the structure of transmission network and the configuration of energy storage system. IEEE RTS-24 bus system is selected as an example for analysis and verification, and the results demonstrate the effectiveness of the proposed method.
