Communication based on SNMP

Exchanged data specified into a MIB

Monitoring data updated every 10 minutes

… critical periods

+ CO2 + load

In PREMIO, upstream operators are simulated:

Critical periods based on CO2 emissions from the national electricity generators

Critical periods based on load peak constraints at local level


PREMIO’s platform can integrate other types of upstream operators:

French TSO (RTE) will send to the control unit critical periodsbased on regional constraints (load peaks and fire threats)

Focus on…



… request for load reduction

Two types of request:

Day-ahead requests are sent one day before the application. They cover the 24 hours of the following with a time step of 30 minutes

Day-of requests are sent the same day of the application. They cover a period up to 4 hours with a time step of 10 minutes

Focus on…



… dispatching

Minimization of the load reduction costs

Consideration of:

Upstream operator request

Distributed resources’ technical constraints

Customers’ comfort

Use of Mixed Linear Programming to solve the optimizationproblem

Very large problem that can take many hours to be solved

Approximation through time limitation during the tree explorationApproximation through time limitation during the tree exploration

Most of time, the observed gap to the optimal solution is low (< 5%)
