Power development planning considering regional constraints

Government imposes power development plan (PDP) to develop the national energy security and to promote the renewable energy and energy conservation programs. However, without considering regional conditions, it may cause generation-demand unbalanced in some areas that leads to system instability and unnecessary transmission expansion. This paper proposes a policy-based power development planning with consideration of regional constraints. An index based on multi-area reliability concept is used as a key indicator to determine a proper location for future power plants if needed. A simplified PDP algorithm with regional constraints is proposed. This method is suitable for policy-based planning. The proposed method has been tested with a modified Thailand generation system. Total costs from the conventional method and from the proposed method are investigated and then compared.
