D2-01_37WAN Network Communications Architectures for Smartgrids: Case Study comparisonAuthors: Arzuaga, A. Alvarez, M.A, Martinez, S. Arzuaga, T. Zamalloa, M. Rao, J. Hampesh, T. SC D2 2013 Colloquium in Mysore, Karnataka, India
Case Study A (Europe) DMVPN architecture with NHRP and IPSec
Case Study B (Europe) Cellular core network services architecture
Case Study C (India) Cellular based VPN
Special Report Questions • Q1-45. What are the reasons for implementing three different WAN communication architectures used in large scale Smartgrid projects presented in the paper, using cellular networks only? • Q1-46. Are those Utility Companies foreseeing cellular networks as the best option for implementing smart grids? • Q1-47. Which are the standards of cellular networks that have been selected?
S.R. Q1-45 • Q1-45. What are the reasons for implementing three different WAN communication architectures used in large scale Smartgrid projects presented in the paper, using cellular networks only? • A: Case study B onlyimplements WAN links withCellularnetworks as itismaking use of the core network services providedby the cellularoperator. However case studies A and C can use othertechnologiesbesidesCellular. Howeverdue to itsadvantages, cellularconsiston 50% (Case A) to 90+% (case C) of the WAN links.
S.R. Q1-46 • Q1-46. Are those Utility Companies foreseeing cellular networks as the best option for implementing smart grids? • A: Itis a simple and convenientoption to deploy a smartgridscommunicationnetworkable to connectwiththousands of fieldpointswith no infrastructure CAPEX and low operationalcosts. However, itdoesnotfulfillall the desiredrequirements in terms of performance, availability and dependability.
S.R. Q1-47 • Q1-47. Which are the standards of cellular networks that have been selected? • A: Currently in Europe and India GPRS/EDGE (2G) and UMTS/HSPA (3G) services are beingusedbyutilities to deploysmartgridnetworks. WCDMA networks are alsobeingused in India. TETRA basedtrunkingsolutions are alsobeingused in EMEA. WIMAX alsobeingused in selectedareas/marketsdependingonfrequencyavailability.
