Transmission Fixed Cost Allocation Using Game Theory in Multilateral Transactions of Restructured Electricity Market

Abstract

In deregulated electricity markets there is a strong need for effective allocation of fixed costs to market participants. The conventional usage based methods currently employed in market scenario may fail to send right economic signals. Hence in this paper, cooperative game theory is applied for power system fixed cost allocation. Increasing competition in the energy market can help maximize customers’ payoffs. This can be achieved by applying game theory. In this regard, two solution methodologies such as Nucleolus and Shapley value are adopted in a Multi-lateral market. Both the methods have their pros and cons, while it can be inferred that Shapley value is a more preferable method when the solution is in the core of the game. In this paper, these methods are applied in case of IEEE 14 bus, New England 39 bus and Indian 75 bus power system and the results obtained are compared with the conventional usage based methods
