  1. Hybrid power systems and renewable energy:Prospects from the IRENA point of viewRoland Roesch IRENA Innovation and Technology Centre (IITC)RRoesch@irena.org16. January 2013

  2. Content • The Challenge • Memory components of the hybrid systems • Structure of the hybrid systems • Combination of hybrid storage options (Example) • System Penetration • Integration Technology

  3. The Challenge • No technology (alone) solves the problem! • Combination of the most economical storage technologies, load- and generation management and additional producers / consumers to hybrid city store • Sources: • Adapted from: Fraunhofer UMSICHT, Hybrid urban energy storage, (May 2012)

  4. Memory componentsof the hybrid systems • Additive Generation: • Application: for rare short-term peak • Technology: For example. Emergency diesel generators (hospitals) • DispatchableGeneration: • Application: for frequent short, high peak • Technology: Power-/heat micro-CHP (Virtual Power Plants) • Energy Storage: • Application: daily cyclical balance of load and generation • Technology: For example. decentralized lithium battery or central redox flow battery • Dispatchable Load: • Application: compensate for frequent short, high production peaks • Technology: For example. Power-/heat pumps, hot water tank • Additive Load: • Application: compensate rare production peaks • Technology: For example. District and local Heating with current heat • Sources: • Adapted from: Fraunhofer UMSICHT, Hybrid urban energy storage, (May 2012)

  5. Combination of hybrid storage options CHP = emergency power unit DH = district heating Load [kW] • Example: • Emergency diesel CHP • Distributed lithium batteries • Micro-CHP with thermal memory • Central redox flow battery • Heat pump with thermal memory • Distributed lithium batteries • DHW • Current into the district heating network “Storage” -load Capacity[h] • Sources: • Adapted from: Fraunhofer UMSICHT, Hybrid urban energy storage, (May 2012)
