Calculation of nodal gas prices using a game theory method

The paper proposes different approaches to the determination of a nodal gas price component that corresponds to the cost of transportation constraints. To this end the research focuses on such methods for calculation of nodal prices as traditional, contribution factor, average prices and the Aumann-Shapley method given in the game theory for allocation of total costs. These methods were applied to calculate the cost of transportation constraints for a test and real gas supply systems. In the paper the discussed methods are compared to the Aumann-Shapley method.
