2. An Integrated Tool for Optimal Active Network Planning
has raised requirements for new planning methodologies
Evolution of Electric Power System and Electricity Supply Market
New planning tools should have the following characteristics:
deal with uncertainty
deal explicitly with risks
deal with multiple criteria
enable consideration of multiple and diverse solutions
use appropriate graphical and mathematical decision techniques
use appropriate time schedules and planning horizons
enable reuse of model, data and solutions

3. DECISION THEORY and RISK ANALYSIS APPLICATION
SPREAD
Optimal Siting and Sizing of EG considering production costs, energy prices, power quality and cost of grid upgrading.
PREDA
finds the optimal network evolution during a prefixed study period in given scenario.
PROLOCOGD finds the optimal EG arrangement in a fixed network structure.
TEODORA takes into account uncertainties, characterized by subjective probabilities, in the knowledge of some parameters and different scenarios.
DECISION THEORY and RISK ANALYSIS APPLICATION

4. An Integrated Tool for Optimal Active Network Planning
SPREAD
An Integrated Tool for Optimal Active Network Planning
able to deal with uncertainties related to a massive EG penetration
use of heuristic techniques developed by the authors
useful tool for medium and long term planning (real size distribution networks)
Integrated Planning Studies:
Optimal network evolution with optimal amount of EG placed in the most convenient points by iterating this procedure.

5. Conclusions: Active Networks: strongly interconnected
subdivided into small cells
locally managed by a power controller
enhances the service provided
Intentional islanding:
development of new control algorithms for a rapid network reconfiguration
new role as wiring companies
Discos:
how much EG to authorize or where to locate their own EG
