Problems solved by technology

Its advantage is to only necessitate few data, but it does not allow an optimum driving, that is a driving maximising consumption of the locally produced energy.
It is therefore based on predictions consisting of long data series throughout a production / consumption period (typically one day) which often have a significant error level resulting either in the consumer's dissatisfaction in terms of comfort and / or need, or in a sub-optimum driving.

Embodiment Construction

[0043]Unless otherwise indicated, a same element appearing on different figures has a single reference.

[0044]In the following, the notation hereinafter detailed will be used.

[0045]Each consumer is associated with an index i, said index being such that i∈[1,I] with I being the total number of consumers.

[0046]Each time range of the production / consumption period is associated with an index k, said index being such that k∈[1,K], with K being the total number of time ranges during the production / consumption period. Moreover, each time range has a time duration Δ so that K×Δ is equal to the duration of the production / consumption period. In the following, the term “instant k” will be used to refer to the time range k. For example, A can be equal to one minute and K equal to 1440, which corresponds to a 24 h production period. The instant k should be understood as the instant during which the state of the consumer is determined and during which the set point is established using a method ac...

Abstract

A method for determining a preferential minimum power set point by a consumer i, said consumer including an electric water heater, the method including determining the state of the consumer i at an instant k; determining a minimum power set point Pcmin(i,k) at the instant k as a function of the state of the consumer i determined during the determining of the state of the consumer i at an instant k; determining a minimum power set point Pcmin(i,k+1:K) at the instants k+1 to K as a function of the predicted state of the consumer i estimated from the state of the consumer i determined during the determining of the state of the consumer i at an instant k; determining a preferential minimum power set point Pcmin_pref(i,k) as a function of the minimum power set point Pcmin(i,k) at the instant k and of the minimum power set point Pcmin(i,k+1:K) at the instants k+1 to K.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The technical field of the invention is that of driving of hot water consumption for the purpose of maximising renewable energy self-consumption. More particularly, the invention relates to a method for determining a preferential minimum power set point as well as a method for driving a plurality of water heaters on a network including a plurality of consumers i. It also relates to a device implementing such methods.TECHNOLOGICAL BACKGROUND OF THE INVENTION[0002]In the context of renewable energy production, for example using a photovoltaic panel, it is known to individually drive each facility so as to satisfy each consumer's demand while maximising the consumption of locally produced energy. However, it may be advantageous to manage production, no longer individually, but collectively by distributing locally produced energy between different consumers depending on needs. To do so, it is possible to complete the facility with batteries or any o...
