How did we come to this day
Smart Grids;
Smart meters;
Energy Efficiency;
Demand Side Response;
DSM from distribution customers;
Business models for emerging energy applications (smart heat, electric vehicles, energy storage);
Barriers to market for the demand side.

How did we come to this day
Quotes
Smart Grids have a major contribution…
Will involve a variety of parties..
.. The critical key element will be the demand response of consumers..
..unclear how the benefits in the system will pass to the consumer

How did we come to this day
The DC alternative
DSM by simple voltage control;
Naturally congestion management;
More privacy, no big data;
More power over existing cables, less grid reinforcement;
Energy/material/space savings;
Higher lifespan/reliability;
Equipment often DC-ready;

How did we come to this day
The DC alternative
Could DC Grids have a even more major contribution…
Would it involve less parties..
Costs and benefits in the system more equally shared..
No critical demand response of consumers..

Why
Why?
For (macro - nano)grid planning and related investments, it is important to have an insight of the new technologies supporting different grid architecture and topology and to identify the related socio-economic costs and benefits.

Why
Key research question
‘what current carrier (AC, DC or Hybrid) on which level in the electricity network can accelerate the European Union (EU)’s Member States in achieving the ambitious security of supply, sustainability and competitiveness targets defined in the EU energy policies, with the most desirable socio-economic costs and benefits.’
