14 INTEGRATING LARGE STORAGE CAPACITIES INTO LOCAL AND PUBLIC GRIDS A1. supports the growth of renewable energy A2. A3. A4. increases solar energy in diesel hybrid systems provides grid ancillary services optimizes load profile

15 RENEWABLE INTEGRATION SUPPORTS THE GROWTH OF RENEWABLE ENERGIES In this application the storage system complement the PV power plant to fulfill requirements that cannot naturally fulfilled with the renewable source alone Storage provides renewable energy with the same grid-stabilizing characteristics of conventional power plants through the comprehensive provision of ancillary services Title of presentation, Author 1) Total Cost of Ownership 15

16 LARGE-SCALE STORAGE INTEGRATION SUPPORTS THE GROWTH OF RENEWABLE ENERGIES Which features to be fulfiled by Storage System? Fullfillment of Regulations and Grid Requirements 1 IPP and/or EPC require a comprehensive solution to fulfill the requirements > Ramp-Rate Control of PV Plants: Batteries provide reserve power to firm the output of the PV system and ensure stable power supply. Makes PV power dispatchable > Frequency Control/Regulation: Batteries provide/absorb power to support frequency in the grid (Spinning Reserve) Title of presentation, Author 16

17 PV-DIESEL HYBRID SYSTEM Extend/Optimize PV DIESEL HYBRID SYSTEMS Increases PV penetration in of-grid diesel based electrification leads to more fuel saving Optimization of genset runtime and efficiency reduces O&M costs significantly Title of presentation, Author 1.Placeholder 17

18 A2. LARGE-SCALE STORAGE INTEGRATION COMPLETES PV DIESEL HYBRID SYSTEMS Which features to be fulfiled by Storage System? > Increase PV penetration: Increased intermittent PV power will be buffered by the storage system not curtailed A higher share of solar PV energy results in increasing fuel savings. > Ramp-Rate Control of PV Plants: Batteries provide reserve power to firm the output of the PV system and ensure stable power supply. Makes PV power dispatchable > Optimized Operation of Genset: Storage utilization to react on PV drop and load changes reduces the running reserve capacity of the generators. Improving operating point of gensets, increase efficiency, reduce O&M Title of presentation, Author 1.Placeholder 18

19 PV DIESEL HYBRID SYSTEMS WITH THE SMA FUEL SAVE SOLUTION..and why Storage System? Battery storage solution is very adequate for PV Diesel Hybrid System due to the following facts: Fast power response Comprehensive provision of ancillary services, all in one device Component modularity & Scalability Easiness of installation According to the system requirements and characteristics the storage business case is given..and by combining different use cases with the same device it can be improved Title of presentation, Author 1.Placeholder 19
