Present state and future plan of standard model development for smart grid simulations

The government of Japan assumes that a large portion of renewable energy in the near future will be provided by photovoltaic generation systems installed at end consumers. Thus, smart grids in Japan will be established mainly at the distribution and the end-consumer level of power systems. Considering this situation, the Smart Grid Working Group, created inside the Cooperative Study Group on Applications of Power Electronic Simulations of IEEJ (Institute of Electrical Engineers of Japan), is currently discussing and developing standard simulation models for components of the distributionand the end-consumer-level power systems. These components include distribution substations, distribution lines, voltage regulation equipment, pole-mounted transformers, photovoltaic panels, power conditioning systems, Li-ion batteries, and small and micro wind power generation systems. The purpose of developing the standard models is to use in transient simulations related to smart grids. This paper describes the present state and the future plan of the development of the standard models.
