| description | In response to energy security concerns, distributed generations such as wind turbines, photovoltaic systems, and diesel generators have been increasingly utilized in many countries. However, the integration of these systems can result in challenges such as supply–demand imbalances, voltage rise, and protection issues in the utility grid. To address these challenges, various methods for accommodating renewable energy sources using self-employed power lines have been proposed. This paper presents a model for quantitatively analyzing the reliability of the power system and the associated economic impact of multiplexing power supplies in a power-sharing network, referred to as a digital grid. A case study of the electrical power system on Okinawa Island is presented, which demonstrates that the reliability of the power system can be improved through multiplexing the power supply using a triple-line, with an acceptable economic impact. |
