Abstract

A method of controlling an electricity production station including at least one renewable energy source and an energy accumulation system, allowing an operator to commit, at an electrical distribution network manager, to a power profile PG that the station will be able to deliver over a forthcoming time period. The declared power profile must, furthermore, comply with constraints imposed by the manager of the electricity distribution network. Non-compliance with this commitment may be subject to penalties. It is then incumbent on the operator to best optimize the method of controlling the electricity production station so as to maximize the electrical power fed into the network, while complying, in so far as possible, over a certain tolerance range, with the power profile commitment PG.

Dependent claims

A method of controlling an electrical energy production station comprising at least one renewable energy source, and at least one energy accumulation system, the method comprising:

a step of determining, via an optimal module, a power profile PG to be declared, the power profile PG being a profile of a power intended to be delivered over a time period T, starting at an instant t0, by the electrical energy production station, the power profile PG being determined with respect to a power profile production forecast PRP for at least one renewable energy source, and corresponding to a power profile P(t) for maximizing an objective function F of the form:

P(t) being a power at an instant t of the period T, SOC(t) a state of charge, which is adjustable, of the energy accumulation system at an instant t of the period T, ρ is a weighting factor, and Cbat being the capacity of the energy accumulation system,
the power profile PG being subjected to a constraint of the form:
PG≤θ2·PR−Pbat
Pbat being the power consumed by the energy accumulation system,
the quantities θ1 and θ2 corresponding to components of a design predetermined vector θ.
