| Summary/Abstract |
The new energy requirements that will be necessary in the coming years will demand a change in the current paradigm of electricity grids. The need to integrate a higher level of renewable resources to achieve the objectives set by the EU (the famous 20-20-20), flattening the load curve, the imminent arrival of electric vehicles, and the possibility of actively controlling all devices connected to a grid, are some examples of these new challenges. In order to maintain the stability of the distribution network, all medium-voltage lines in the city of Malaga (Spain) have been analyzed and modeled over the past five years, to optimize electric-vehicle charging with the use of available energy during the night valley using pricing signal, control of the electric vehicle charging manager and signals from the Distribution Company, with regard to grid availability (vehicle-charging posts) and available energy. The project has developed new management, control and integration systems for all elements of consumption, production and energy storage over the distribution network. All deployment within the SmartCity Málaga Project of ENDESA includes smartmeters for all customers and new automation and communication systems over the grid connected by a broadband Power Line Communication network.

| Summary/Abstract |
This paper defines and compares two strategies for integrating intermittent renewables: SuperGrid and SmartGrid. While conventional energy policy suggests that these strategies may be implemented alongside each other, the paper identifies significant technological and socio-economic conflicts of interest between the two.
The article identifies differences between a domestic strategy for the integration of intermittent renewables, vis-à-vis the SmartGrid, and a cross-system strategy, vis-à-vis the SuperGrid. Policy makers and transmission system operators must understand the need for both strategies to evolve in parallel, but in different territories, or with strategic integration, avoiding for one strategy to undermine the feasibility of the other. A strategic zoning strategy is introduced from which attentive societies as well as the global community stand to benefit.
The analysis includes a paradigmatic case study from West Denmark which supports the hypothesis that these strategies are mutually exclusive. The case study shows that increasing cross-system transmission capacity jeopardizes the feasibility of SmartGrid technology investments.
A political effort is required for establishing dedicated SmartGrid innovation zones, while also redefining infrastructure to avoid the narrow focus on grids and cables. SmartGrid Investment Trusts could be supported from reallocation of planned transmission grid investments to provide for the equitable development of SmartGrid strategies.
