Grid applications for energy storage Grid connection of renewable generation When connecting large wind farms to the power grid, they will typically be connected to weak grids. Issues such as:  steep power changes  voltage control  grid stability during and after faults and  frequency regulations are areas where the new DynaPeaQ system supports the wind farm. © ABB Group October 1, 2016 | Slide 3

Grid applications for energy storage Backup power DynaPeaQ continuously supports the grid with reactive power and in case of generation loss DynaPeaQ will push active power into the grid until new generation is available. © ABB Group October 1, 2016 | Slide 4

Grid applications for energy storage Intermittent loads of a railway Accelerating a heavy train can expose the grid to a peak load that traditionally gave rise to extensive capacity build out investments. With DynaPeaQ the required acceleration power is literary taken from the train’s latest deceleration. © ABB Group October 1, 2016 | Slide 5

Grid applications for energy storage Emergency and short-time power In a distribution grid a compensator for reactive power would typically provide for power quality improvement. The energy storage adds a whole range of new functions.  In cases where local loading exceeds grid capacity DynaPeaQ provides load support  After black-out restoration, the Energy Storage might be the starting point  For sensitive loads, the Energy Storage can provide overbridging power between outage and backup power © ABB Group October 1, 2016 | Slide 6

Grid applications for energy storage Smart Grid Smart Grid applications with DynaPeaQ:  Provides possibilities for connection of renewables  Dynamic energy storage  Integration of electric vehicles  Peak-load shaving  Ancillary services © ABB Group October 1, 2016 | Slide 7

Grid applications for energy storage Economical models Deregulation provides new possibilities  Take advantage of electric energy price difference  Buy cheap – Store – Sell at higher price Industry electric supply  Reduce power peaks to cut costs (tariff issue)  Postpone investments in grid strengthening © ABB Group October 1, 2016 | Slide 8

DynaPeaQ Series connected battery rooms  Battery rooms combined with service corridors  Either containerized or site buildings © ABB Group October 1, 2016 | Slide 13

DynaPeaQ Grid interface  Energy storage connected to the DC side of ABB SVC Light ®  Storage size depending on power level and discharge time  Discharge followed by charge  Focus on “dynamic” properties:  Large number of charge and discharge cycles  High power during relatively long discharge time  ABB has selected a high performance battery as storage © ABB Group October 1, 2016 | Slide 14

DynaPeaQ Typical single line diagram Scalability Project depending number of battery strings is included. At a later stage, more battery strings can be added, for higher power and energy. Typically, converters have margins due to reactive power requirements. Flexibility Charging and discharging are fully flexible to the extent that, according to need, high power can be charged/discharged for a short time (power applications), or low(er) power for a long(er) time (energy applications) © ABB Group October 1, 2016 | Slide 15
