ABSTRACT
To reduce the environmental impact caused by the life cycles of various industries and technologies, small-scale power generation systems, such as solar power plants, are being increasingly connected to distribution equipment. These distributed power resources are expected to help reduce power supply interruptions caused by accidents or natural disasters. This paper aims to provide insights that contribute to the formulation of effective and efficient deployment plans for distributed power resources across the entire electrical distribution network. First, we evaluate the expected Power Outage Recovery Time Expectancy (PORTE) for users during an earthquake using probabilistic methods, based on a hypothetical distribution network model as a case study. Then, we evaluate the power supply curve of the electrical distribution network during an earthquake when distributed power resources are preferentially deployed to users who PORTE is predicted to be prolonged, and show its improvement effect.
