Of Smart Grid Paul Johnson Standards are the “Chromosomes” of Smart Grid Paul Johnson (TC 57) and Roland Hill (TC 13) SA National Committee of the IEC Presenter Paul Johnson Standards are the “Chromosomes” of Smart Grid • Smart Grid is not a thing, but a vision – it is and will be a never ending evolution • Only a smart grid vision built from strong “Chromosomes” [Standards] will adapt, survive, and grow, thus delivering value up to the expectation • Suitably engineered portfolio of standards will make it happen and sustain it 22 Summary • Smart grids in the context of Africa • The standardization challenge -globally • The challenges for Africa • What is happening internationally • IEC’s strategic approach • How is Africa engaging in this work • Role of AFSEC and national electrotechnical committees • Recommendations 3 Smart grids in the context of Africa • As with other developing economies, the technologies now available to the electricity supply industry offer Africa the opportunity to ‘leapfrog’ technology: in many cases from a “no-grid” status to a vastly improved electricity infrastructure. • The decision to ‘smarten the grid’ will depend on the business goals of each individual utility or country. • To manage the balance between demand and supply, • For better manage revenue management • To manage technical losses • Environmental management implications, • Smarter management of scarce resources • For integration of distributed generation • To achieve increased reliability 4 The standardization challenge - globally • However we choose to define ‘smart’ , or ‘smarter’ grids, fundamentally there will be an ever increasing application of ICT to manage the electricity grid. • The need for a systems approach is evident, with the breaking down of traditional organizational and technical ‘silos’. A evolution away from specifying functions of equipment in isolation, towards specifying the interfaces between components and subsystems that make up the electricity supply chain –from central generator to the end customers’ equipment • Thus the standards development bodies (SDOs) and user groups are challenged to also cooperate more closely 5 The standardization challenges - globally • Lack of awareness • Many standards developing organizations • Nature of electricity networks –many nodes ; tightly coupled; operating in real time • Integration of ‘short life span’ ICT with ‘long life-time’ electricity network assets • Interoperability required at all levels 6 The standardization challenge –for Africa • All the above AND • Many countries have a fragmented and incomplete electricity grid • Islands of customers supplied remotely and independently • Majority of population yet to be connected to a grid • Development of regional power pool networks and their interconnection are priorities to help balance demand/load 7 The challenge for Africa Some 75% (500million and growing) waiting for The size access to implies electricity and massive needs electrical and appliances opportunities conforming to for appropriate infrastructure standards development – requiring appropriate standards Acknowledgement Map - Spoor & Fischer Electricity consumption in Africa 1800 1600 1400 Southern 1200 North 1000 West Central 800 East 600 400 200 0 kWh/YEAR kWh/year one 8 W CFL running for a year!

These will not integrate easily into a smart grid. Think long term • Do allocate resources to understand how the technology you are investing in today will interoperate with other systems • The business case for the initial building blocks (e.g. smart metering systems) needed will require a strategic motivation • The real return will be realised when these are integrated with other system (outage management, network optimization etc, etc) • Participate in AFSEC to share information about the standards available and how they can be implemented in African • Know what you have already – can it migrate/ be adapted to/integrate with the systems you are going to invest in 2424 FINAL MESSAGE Direct participation in Standards standardisation activities committee is not a ‘nice to have’ or something to be left to be done by others. It is a growing necessity that Africans need to embrace for successful evolution of a smart grid vision Thank you ! 25.

    Cyber Security Practical considerations for implementing IEC 62351 Frank Hohlbaum, Markus Braendle, Fernando Alvarez ABB [email protected] Switzerland 1. Introduction Two trends are currently changing substation automation systems: IEC 61850 and the need for increased cyber security. IEC 61850 has gained global acceptance by both vendors as well as customers. Cyber security on the other hand has quickly become one of the most dominant topics for control systems in general and electrical utilities in particular. The combination of the two, securing IEC 61850 based communications, has been one of the goals of the recently published technical specification IEC 62351. In the authors‟ view IEC 62351 is overall a good starting point and will be the future standard to help secure IEC 61850 communication. However, there are some shortcomings of the current standard and some challenges that need to be addressed before IEC 62351 can be implemented and gain wide acceptance. This paper will highlight the challenge of addressing secure communication in the substation real-time environment, complying with the IEC 61850 real-time specifications. The major difficulties are to reach the performance defined in IEC 61850 for GOOSE and SV data with today‟s proposed technical specification defined for IEC 62351 part 6. In chapter 2, we will give a short overview about the structure of IEC 61850 as well as the detailed performance requirements for the various data types. Chapter 3 will present an introduction of the IEC 62351 standard including the used methods to secure the IEC 61850 communication. Chapter 4 will then show the major implementation issues of IEC 62351 part 6.
