Storage: A Potential Solution
Capacity firming output from solar Power Plant can be maintained at a committed (firm) level for a period of time to eliminate rapid voltage and power swings on the electrical grid.
Load leveling store the power during low demand and use the stored energy when the demand increases
Voltage support An energy storage system can help to maintain thegrid voltage by injecting or absorbing both active and reactive power.
Peak shaving Peak shaving is similar to load leveling, but may be for thepurpose of reducing peak demand rather than for economy of operation.
Improve Power System Stability

Understanding Energy Performance
The fundamental metrics used to define a storage technology for most electricity grid systems include: Energy storage capacity [kWh or Ah]; Charge and discharge rates [kW or A]; Lifetime [cycles, years, kWhlife]; Roundtrip efficiency [%]; Initial capital costs Operating costs

Advantages and Constraints of Storage SolutionsStorage Technology Advantages Constraints
Lead-acid batteries Widely available, moderatecosts, modular
Limited lifetime, must be disposed of properly, must be maintained properly
Li-Ion batteries Rapid technological improvement,compact in size
Rupture risk, little experience with use in electric grids
Na-S batteries Can be used for ancillary services,high roundtrip effi ciency
Suitable only for larger electricity systems, corrosivechemicals
Flow batteries Can be fully discharged, somewhatmodular
Still under development, higher capital costs
Flywheels Modular, low maintenance Expensive
Pumped Hydro Technically proven, low costs Very large scale, significant environmental impacts of construction
CAES (compressed air energy storage) Moderate costs Very large scale, uses natural gas
Hydrogen Can be used as a transportationfuel, compatible with fuel cells Low roundtrip efficiency, expensive

Energy Drawn from different sources
Micro GenerationEnergy obtained on a small scale can reduce the demand on the grid
Larger NetworkCan generate own power through solar panels, wind turbine and in turn can supply energy back to grid
Energy StorageEnergy generated during Non Peak times can be stored for future use

Energy Storage Application :Rural electrificationOff Grid with Energy Storage
Rural electrification today
Power supply unit
GenSet replaced by a main Power Supply Unit
New distributed power sources
GenSet with decentral PV and storage
For small and medium system with concentrated resources
For large system with dispersed generation (example: big island )
Product Presentation 12
Off grid with PV, GenSet and storage
- Power supply unit integrating - PV+Wind+Hydro + Genset
Voltage fixed by Power Supply unit no control issue Reduced diesel consumption according to battery sizing GenSet is working only if low battery and no other resources
