Abstract

Investigating flexibility and stability boosting transmission expansion planning (TEP) methods can increase the renewable energy (RE) consumption of the power systems. In this study, we propose a bi-level TEP method for voltage-source-converter-based direct current (VSC-DC), focusing on flexibility and stability enhancement. First, we established the TEP framework of VSC-DC, by introducing the evaluation indices to quantify the power system flexibility and stability. Subsequently, we propose a bi-level VSC-DC TEP model: the upper-level model acquires the optimal VSC-DC planning scheme by using the improved moth flame optimization (IMFO) algorithm, and the lower-level model evaluates the flexibility through time-series production simulation. Finally, we applied the proposed VSC-DC TEP method to the modified IEEE-24 and IEEE-39 test systems, and obtained the optimal VSC-DC planning schemes. The results verified that the proposed method can achieve excellent RE curtailment with high flexibility and stability. Furthermore, the well-designed IMFO algorithm outperformed the traditional particle swarm optimization (PSO) and moth flame optimization (MFO) algorithms, confirming the effectiveness of the proposed approach.
