【DBJ Research No.429】Securing Grid Flexibility for Renewable Energy Integration

Because the expansion of the share of solar and wind power generation towards carbon neutrality causes variability and uncertainty in electricity supply, it is necessary to ensure flexibility by utilizing not only demand response (DR) as mentioned in DBJ Research No. 427, but also battery storage and long-duration energy storage (LDES).　In this paper, we examined the overall picture of flexibility and promising technologies.
