| Abstract |
In order to minimize transmission constraints when delivering electric power from non-metropolitan areas to metropolitan area through the seven metropolitan tie-lines, it is necessary to construct eco-friendly power plants and transmission networks. This paper proposes the introduction of distributed pumped storage power generation utilizing the upper reservoir of an existing multipurpose hydroelectric power plant. First, based on the power system data of the 10th Basic Plan for Supply and Demand of Power, we analyze the northward current by assuming that 3GW of distributed pumped storage power generation is connected to the metropolitan area using PSS/E. We propose a congestion control method using the PTDF and GSF based on the change in the active power. Finally, we calculate the congestion of the seven metropolitan tie-lines and evaluate the effectiveness of the proposed distributed pumped storage power plant using PTDF and GSF. |
