Benefit Based Transmission Expansion Planning for ASEAN Power Grid

This paper presents the cost-benefit assessment related to ASEAN Power Grid (APG) integration. This paper explores the benefit of investment in APG by means of cross-border electricity transmission investment in ASEAN region by 2030. The benefit of investing in the cross-border transmission is analyzed by considering the expected generation portfolio. The net market evaluation framework of APG interconnection is developed, including consumer, producer, and transmission owner benefit for APG interconnection. The impact of cross-border transmission capacity on the net market benefit is analyzed by considering the cross-border transmission capacity limit reported by the ASEAN Centre of Energy (ACE) and optimal transmission limits. The study has been conducted in Matlab/MATPOWER using the simulation model of APG.
