Market based transmission expansion planning: stakeholders' desires

In unbundled power markets, stakeholders have different interests and expectations from performance and expansion of the system. This paper presents a new market based approach for transmission expansion planning with consideration given to the stakeholders' desires using fuzzy decision making. Five groups of stakeholders; power producers, demand customers, system operator, network owners, and regulator, are considered. Competition, reliability, flexibility, network charge and environmental impacts are evaluated from the viewpoint of different stakeholders for selecting the final plan. Some market based criteria are presented to measure stakeholders' desires. The approach is applied to IEEE 30 bus network.
