Why will energy storage solutions be so important?
• Grid stability and power reserve
• Wind Power & PV connect via power electronics to the grid are very different to sync. generators
• RE are causing significant fluctuations in generation, which require control power reserve (to be provided
by energy stored from renewables) -
• Supply security and energy reserve
• Seasonal characteristics of RE (less PV during cold seasons, less Wind during hot seasons)
