Functional Requirements§ Reliability function-Islanded operation§ Battery charging from network§ System frequency supporthttps//www.youtube.com/watchv1_p3TtG326s 27-Apr-19Page 23 Strengths§ Liquid Cooled Inverters that provide removal of approx. 95 of heat losses to externally mounted heat exchanger greater efficiency. This results in low HVAC requirements within outdoor enclosure, as compared to air cooled inverter configuration. § Fully enclosed dust proof enclosures. § Siemens Service Support, local Centre in Perth.§ Voltage regulation in unbalanced network § Strong application know-how. Reference CasePerenjori – BESS – 2.4MW/1.1MWh Siemens AG 2019 § End User Territory Generation§ Location Alice Springs, Northern TerritoryProject DetailsThe battery array, 5MW with 40 minutes of storage is designed to cover the variability of solar generation, particularly as clouds pass over the solar arrays. It a response to some of the grid management issues that Territory Generation was experiencing in Alice Springs, which has the highest solar penetration in AustraliaFunctional Requirements§ Provide frequency control ancillary services FCAS§ Enable reduction of spinning reserve from gas generators§ Smooth the impact of variable solar generation, thereby also enabling further penetration of solar PV on the network§ Provide peak shaving in order to defer transmission system upgrades§ Provide reactive power and voltage control at the local bushttps//player.vimeo.com/video/210792675title0byline0portrait0 27-Apr-19Page 24 Strengths§ System designed to have ability to augment the storage capacity with further batteries in the future§ Sized to provide reactive power balance capability§ Voltage regulation in unbalanced network § Energy dense design in rugged containerised solution with small footprint in harsh conditions “That will mean a significant reduction in the amount of gas burned for electricity, and will mean significantly less “spinning reserve” is needed. That will also mean a big reduction in Co2 emissions.” –Tim Duignan TG CEO Reference CaseTerritory Generation– BESS – 6MW/2MWh Siemens AG 2019 Thanks Prepared by Mr Dinesh KathriarachchiHead PCI APC ASIA PACMs Yi LiuPCD Product Manager, LD P China 4/27/2019 PCI Business for APAC MarketPage 25
