Robust transmission network expansion planning method with Taguchi's orthogonal array testing

摘要

This paper proposes a robust transmission network expansion planning (RTNEP) method with Taguchi's orthogonal array testing (TOAT) which considers generation dispatch and operating uncertainties caused by load demand and renewable energy output. TOAT is a method which has been proven to be optimal to select representative scenarios for testing from all the possible combinations. This paper employs TOAT to determine testing scenarios in transmission network expansion planning (TNEP). A new RTNEP formulation is then proposed based on the multiple testing scenarios. The simulation results have demonstrated the effectiveness of the proposed RTNEP.
