What is a Smart Grid?“Smart Grid means that you fill up your car with hydrogen but can not drive it the next day because your teenage daughter has sold the hydrogen as electricity at peak tariff over the internet and used the proceeds to charge her mobile phone card” (Hans de Keulenaer)Source: Transmission and Distribution October / November 2009
“A Smart Grid is like a brain which is a society of very small, simple modules that cannot be said to be thinking, that are not smart in themselves. But when you have a network of them together, out of that arises a kind of smartness.”Source: Kevin Kelly

European Technology Platform Smart Grids
• A Smart Grid employs innovative products and services together with intelligent monitoring, control, communication, and self-healing technologies in order to:– Facilitate connection and operation of generators of all sizes and
technologies– Allow consumers to play a part in optimizing system operation– Provide consumers with greater information and options for choice
of supply– Significantly reduce the environmental impact of the whole electricity
supply system– Maintain or even improve the existing high levels of system
reliability, quality and security of supply– Maintain and improve the existing services efficiently– Foster market integration towards an integrated market

Drivers and Benefits
• The smart grid plan offers the hope that it “will save us money, protect our power sources from blackout or attack, and deliver clean, alternative forms of energy to every corner of our nation.” - Barack Obama

Smart Grid The Drivers in General
• Utility Operational Improvement• Regulatory• Legislative• Consumer Advocacy• Environmental • Depletion of Resources• Costs• Technology – because we can• …

WHAT IS NEEDED?Smart Grid

Smart Grid – What is Needed?
1. End user acceptance and participation– Tell the user what you are planning and doing– Ask users for input, feedback and ideas AND LISTEN!– Clear and tangible benefits – no false promises!
2. Definition and participation of self producing consumers (prosumers) that play an active role in balancing their own, local and regional demand and supply
3. Better information about the electrical system status, its usage, its efficiency and its balance more control!
4. Regulation– Clear and well defined regulation allows for the justification of utility
investments as well as end user participation

POSSIBLE DIRECTIONS FOR CURACAO
Smart Grid
© 2012
Substation and Distribution Automation
• Better information regarding the high, medium and low voltage infrastructure
• More control faster response to unbalances in the system
• Goes together with making the grid smarter, distributed generation and renewable energy
© 2012
Smart Homes
• Smart Meters? - the smarter the meter, the sooner it will be old fashioned!
• A normal meter with a smart gateway by its side (integrated with possible home automation) that exchanges information with the utility can be sufficient
• Facilitate different generation types from PV to Fuel Cell
• Prosumer has control acceptance! but… the utility has the possibility to curtail load and shed generation to maintain network stability and change distributed generation output

Power to the People…• Accuracy such that (in combination with a revenue meter)
it can be used for billing
• System can operate stand alone - user shall have access to both data and visualization
• System data is stored locally such that the user can access and control his measurements
• Owner/user chooses if and with whom data is shared
• Data flow to the outside world (e.g. a service provider) is standardized so that it can be used for multiple purposes

CONSEQUENCES FOR CURAÇAOSmart Grid
© 2012
Consequences for Curaçao
• Current base load is 100 MW, peak 130 MW (maybe more)
• Short term 30 MW wind is expected online with an average supply of 15 MW
• Predictions for end 2012 show 8 MW of solar to be installed (and growing…)
• More prosumers will emerge both domestic and industrial
• Regulation is needed
© 2012
Consequences for Curaçao
• Strong(er) distribution grid needed to support prosumers
• Future oriented island wide communication infrastructure
• Support from politics and leading public figures is a must
• (Standardized) Solutions are needed for– Control centers and substations– Customer service– Smart homes– Distributed generation– Remuneration of the utility for the use of the grid

LESSONS LEARNED SO FARSmart Grid

Lessons Learned
• Smart Grid is a hype money and developments are a available but many people still have their heads in the clouds
• Only a few new/revolutionary solutions developed so far
• Still a lot of learning on the job think before you act!
• Nevertheless… there are several trends that can prove to lead to useful solutions
© 2012
The Trend: Smart Homes
Plug-in hybrid electric cars
Distributed Power Sources
Smart thermostats, appliances and in-home control devices
Smart Gateways and Meters Real-time and green pricing Signals
High-speed, networked connections
Customer interaction with utility

The Trend: Smart Meters?
• Have Smart Meters provided what is needed in the long run?
• What about the risk of investments being obsolete before they are recuperated
• Discussions based on first experiences lean towards a smart gateway instead of smart meters
© 2012
The Trend: Distributed Generation
• Yes! – From consumer to prosumer but…
– Transparent regulation is required
– (Future) Prosumers shall be engaged
– Clear benefits shall be identified
– Technologies shall become cheaper and easier to use
– Virtual Power Plants are to be built to support network balancing and continuity of supply
– There must be a Business Case for everyone

CONCLUSIONSSmart Grid

Conclusions• The Smart Grid hype has provoked a waterfall of
discussions, developments and projects - engineers are challenged to make it all work!
• The future is bright with Smart Grids – but – we live a conservative world! – a society wide paradigm shift is needed
• Politicians shall focus on politics by creating a platform for Smart Grid within society and leave the engineering to the engineers…
© 2012
Conclusions
• Prosumers shall be in control of their own systems but with a clear interaction with the utility allowing dynamic and efficient balancing of supply and demand
• A framework shall be in place that allows for remuneration of the utility for the use of its network but that also justifies investing in renewable energy and Smart Grids
• And finally…Let’s stop talking and start doing!
