  3. 3. I. Motivations  At COP 21 in Paris, on 12 December 2015, Parties to the UNFCCC reached a landmark agreement, the Paris Agreement, to combat climate change.  The Paris Agreement aims to stabilise global average temperature well below 2.0 degree  Japan has a long term carbon mitigation target, 80% by 2050.  To achieve target, renewable energy, especially VRE (Variable Renewable Energy), is expected to paly a major role.  Existing energy infrastructure, especially electricity grid, has not been built to absorb high VRE share.  In this research, we have built TIMES-based Japan model which include grid features and GIS-based renewable energy potential information to identify the importance of grid capacity expansion and electricity storage under high carbon mitigation constraints.  But…node resolution simulation requires in-depth understanding on energy issue from system point of view.

  26. 26. V. Conclusions  Node level resolution of model reflects reality which is geological distribution of energy consumption and renewable energy potential and identify the burden of grid infrastructure under high VRE share.  4016electrity prices in one year  Suitable for carbon-free hydrogen and electricity grid storage project.  And EV project e,g, charging pattern management and identify grid restriction to popularize EV.  To make the most use of renewable energy potential, huge grid connections from Hokkaido to Tokyo via Tohoku is necessary to achieve 80% carbon mitigation target by 2050.  No grid connection expansion results in electricity price inequality by node.  Node level resolution simulation results require in-depth knowledge of energy from system views. Non-expert cannot understand the simulation results of node-level model. Copyright 2018 FUJITSU RESEACH INSTITUTE25
