Energy challenges for the 21st century30 Oct., 20132

Geopolitics tensionsGlobal warmingIncrease in pricesGovernments want to secure their reserves and achieve energy independence. The EC 20-20-20 package aims to increase the share of renewable energies to 20% in the European energy mix by 2020. 2013 eStorage

NGrid operators & the constraint ofintermittent renewables30 Oct., 2013

Grid operatorsBalance the supply & demand of electricityConstantly control grid parameters (voltage, frequency) to avoid outages.Solar & wind powerIntermittentNo direct storage solutionImpact grid stabilityNot optimized, often a loss of a free GHG-free powerGRID CHALLENGESFaster plant regulationIncrease regulation capacityStore renewable power produced when not enough demand 2013 eStorage

N Improving PSPs: Variable speed technology30 Oct., 2013

Benefits:Additional flexibility: frequency regulation possible in both modesIncreased performance: increased turbine life, higher operation mode

Fixed speedVariable speed 2013 eStorage

NConclusionThe integration of renewable power generation requires large investments for further development of the transmission and distribution infrastructureNew facilities for production, storage, distribution and consumption must support a higher flexibility of the entire electrical energy systemCommon and clear market rules and associated incentive schemes have to be developed to enable the necessary investmentsIn the eStorage project the feasibility of a flexible large-scale energy storage in combination with an innovative market approach will be demonstrated
