Outline of Research at the Start

The temporal and geographical variability of renewable energy have drawn increasing concerns on their potential shocks to the stability of the power system. This study is to quantitatively assess the impacts of renewable penetration in Japan, considering the connectivity of power grids. Firstly, a theoretical model will be built up to analyze the optimal power flows. Secondly, a simulation model will be adopted to find the relationships between renewable and fossil fuel generators. Lastly, spatial econometric models will be adopted to incorporate the impacts of transmission grids.
