Transmission Expansion Planning with Economic Dispatch and N-1Constraints

Authors: A. Charlangsut, M. Boonthienthong, N. Rugthaicharoencheep


This paper proposes a mathematical model for transmission expansion employing optimization method with scenario analysis approach. Economic transmission planning, on the other hand, seeks investment opportunities so that network expansions can generate more economic benefits than the costs. This approach can be used as a decision model for building new transmission lines added to the existing transmission system minimizing costs of the entire system subject to various system’s constraints and consider of loss value of transmission system and N-1 checking. The results show that the proposed model is efficient to be applied for the larger scale of power system topology.

Keywords: Contingency, economic dispatch, scenario analysis, transmission expansion planning
