Comparative Analysis of WAN Communication Architectures for Smart Grids in Europe and India

This study presents a detailed comparison of three different WAN communication architectures utilized in large-scale Smart Grid projects across Europe and India. It evaluates the implementation of DMVPN with NHRP and IPSec, a cellular core network, and a cellular-based VPN. The findings highlight the advantages of cellular networks, such as low CAPEX and OPEX, alongside their limitations in meeting performance and reliability requirements. The paper also discusses the selection of cellular standards, including GPRS, EDGE, UMTS, and HSPA, and their suitability for Smart Grid deployments.

  1. 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

  2. Case Study A (Europe) DMVPN architecture with NHRP and IPSec

  3. Case Study B (Europe) Cellular core network services architecture

  4. Case Study C (India) Cellular based VPN

  7. 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?

  8. 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.

  9. 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.

  10. 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.
