In recent years, renewable energy sources have been introduced rapidly, and the enhancement of power grid facilities, including tie lines, is under consideration. In addition, the Energy Supply Strengthening Act, which passed in 2020, suggests the possibility of introducing a scheme in which each area shares the cost of the grid enhancement. However, which and how much tie line should be augmented on the economical point of view are under discussion now. Also, how to determine the cost allocation of each area is not completely decided. In this study, a basic analysis of supply and demand operation in multi areas and cost allocation of grid augmentation was conducted by using cooperative game theory concepts. In this study, an annual power supply and demand model was constructed. Simulations were conducted in the current scenario and the 2030 scenario, respectively. Based on the simulation results, the amount of tie lines augmentation was decided. The concept of cooperative game theory, nucleolus, was used to allocate the construction cost.
