BESS RECC for the solution to India network Shinichiro KENGAKU Managing Executive Officer Tokyo Electric Power Company Holdings, Inc. 2016/08/17
1 TEPCO: who are we? (1) 29mil; costumers in the Tokyo metropolitan area. Fukushima nuclear accident and nationalized. World highest reliability. Technical expertise to all over the world. 600 pjts for 70 countries Outage: 4min p.a. (2014,SAIDI)
2 TEPCO: who are we? (2) Paradigm shifting to: the Green & Innovation (G&I) Key techs & applications Utility Scale Battery Energy Storage System (BESS) Renewable Energy Control Centre (RECC) Distributed Generations Big data O&M
3 TEPCO: who are we? (3) We know you; 28 projects in India. 2 year analysis in Rajasthan.
4 Knowledge through analysis in Rajasthan Solar is smaller but wind is higher fluctuation to cause imbalance. How to harness capricious wind generations is the key. Rajasthan s total daily Wind power summary in 2014 (MW) 900MW 72MW
5 Proposing Solutions in Rajasthan BESS RECC Make electricity to be storable Make renewable energy to be tame
6 Proposing Solutions in Rajasthan: BESS X RECC Absorb fluctuation in a gentle way. Suitable capacity size, shorter term construction period. Reduce fuel cost & CO2. BESS Actual generation Reserve Capacity Predicted generation Standby Capacity Dispatch Standby Capacity
7 Proposing Solution in Rajasthan : BESS X RECC Supervises and aggregates the RE resources. Meets suitable supply and demand balance by utilizing BESS. Nuclear power generation plant SCADA or TSC PCS Solar power generation Thermal power generation plant System linkage apparatus Electric power company system Hydro power/ pumped hydro generation plant PCS RECC Power grid Communication grid BESS Supervisory control system (Renewable Energy Control Centre) PCS PCS Wind power generation BESS PCS PCS Solar power generation Wind power generation
8 Proposing Solutions in Rajasthan : BESS X RECC TEPCO has already a concreate proposal of the demo project, based on 2 year analysis. <Assumed Specifications> Power Type Battery(Lithium-ion Battery) - Output : 2MW - Capacity: 1MWh Capacity Type Battery(NAS Battery) - Output : 0.8MW - Capacity: 4.8MWh BESS 3m SLDC/RECC Capacity Type Battery PCS (for Capacity Type Battery) 6m 10m 6m Monitoring, Controlling 3m Auxiliary Facilities (Step-up Transfor mer, etc.) Power Type Battery 2.4m PCS (for Power Type Battery) 3m Substation Power Type Battery 2.4m 3m 4m 3m 12m 7m 3m 3m 3m 35m
9 Proposing Solution in Rajasthan: BESS X RECC TEPCO also has an overall system configuration diagram of RECC for the demo project. SLDC RECC RECC Server SLDC Server RECC Server HMI-1 HMI-2 HMI-1 HMI-2 - Actual wind generation output - Wind generation s prediction data Network - State of charge (SOC) System Image of RECC Site- N Site-A Site-B Trans., etc Trans., etc Trans., etc Local Controller Local Controller Local Controller Battery Storage Battery Storage Battery Storage PCS PCS PCS Battery charging/discharging control
10 Great potential of BESS Also contribute to a future ancillary market. BESS More flexible and cost-effective power source
11 TEPCO Rajasthan aur Bharat ke bijali kshetra ki safalta mei yogdaan karna chaahta hain. Dhanyawaad
