Abstract

Wind generated power is one of the most promising forms of renewable energy and its penetration into power grids is expected to increase in future. For the large-scale penetration of wind farms, it is important to build transmission networks dedicated to wind power generation at low costs and assess the impacts of wind power on the existing transmission networks. For solving these challenges, it is necessary to determine the appropriate capacities of the power lines to be built, and to estimate the additional power flow in the existing lines. In this paper, we propose a current flow analysis method using stochastic power flow calculations and we apply this method to a model system that simulates the power system of Tohoku (the northeast region of Japan). First, we calculate the stochastic maximum current values of the transmission lines of the model system using this method. Next, we calculate the actual current values of the transmission lines of the model system using the measured data of the wind farms in Tohoku. Additionally, we evaluate the effectiveness of the proposed method by comparing the stochastic maximum current values with the actual current values.
