From these measurements, there can be an infinite number of ways in which energy could have passed between the members of the energy community and the public electricity network if the number of measurements is less than the number of electrical flows. Certain energy transfer scenarios can be very advantageous for certain members, and much less for others.

- at least one renewable energy producing system such as at least one photovoltaic panel, at least one wind turbine, a hydraulic power plant, a biomass power plant
- any other power plant for example a nuclear power plant, a gas power plant, etc.
- An energy storage means may in particular be a battery, a compressed gas storage system, a fuel cell, or any similar means.
- the energy community is characterized by a topology, which defines nodes for each component and connections between said nodes.
- the energy community is represented by a network comprising nodes and links between the nodes, the nodes representing the components of the energy community and the links representing the connections between the components.

- This means of measurement is generally called a meter.
- This means of measurement can be certified (official, MID certified for billing) or not certified.
- a certified measuring means is a measuring means whose measurement is correct, and which can be used in particular by the electrical energy supplier for billing. This could, for example, be a Linky meter as deployed in France.
- a non-certified measuring means is a measuring means whose measurement may be subject to measurement inaccuracies. It can be an informal meter placed on a photovoltaic panel or any other component.
- the method according to the invention implements the following steps:
- the steps can be implemented by computer means, in particular a computer, a server or a calculator. Steps 1 and 2 can be implemented once offline, then steps 3 through 5 can be implemented in real time or for a past period. Steps 1 and 2 can be done in this order, in reverse order, or simultaneously. The steps will be detailed later in the description.
- Figure 1 illustrates, schematically and in a non-limiting manner, the steps of the method according to one embodiment of the invention.
- MCF flow conservation model From the TOP topology of the energy community, we construct an MCF flow conservation model and we assign a NIP priority level to each electrical flow in the topology. Electrical flows MES are measured by the measuring means.
- OPT 1 for the first priority level, to determine electrical flows Fe1 according to the MES measurements and the MCF flow conservation model.
- OPT 1 optimization method for the first priority level
- the storage means can be seen as a node that can be divided into a consumer node and a producer node.
- F Pi , cj an electrical flow going from a producer system Pi to a consumer system Cj.
- a priority level is assigned to each electrical flow in the topology.
- the priority level is determined within a classification which includes a first priority level and at least one higher priority level, each higher level being less priority than a lower level (the notions of higher and lower are linked to the number of priority: the first priority level is a level lower than the second priority level, which itself is lower than the third priority level).
- the priority level allows you to prioritize certain flows over others. In other words, the priority level reflects the fact that certain electrical flows can take electrical energy that is available while other electrical flows can make do with the surplus.
- the electrical energy produced by a producing system is intended initially to provide energy to a consuming system, and if all the energy is not consumed, to provide energy to a medium energy storage.
- the flow of energy from the producing system to the consuming system is of first priority level
- the flow of energy from the producing system to the means of energy storage is of second level of priority.
- the priority level can be predetermined, for example by means of an energy community control system, depending on a control strategy applied to the energy community.
- a control strategy may include maximizing the use of energy produced by a producing system within the energy community, maximizing the use of the energy storage system, maximization of the supply of energy to the distribution network, maximization of renewable energy consumption, maximization of a proximity criterion (a producing system will supply electrical energy first to the geographically closest components ), etc. or any combination of these strategies.
- At least one electrical flow is measured at a node by the electrical flow measuring means.
- the electrical flow measuring means we measure an electrical flow entering or leaving a component of the energy community.

- electrical flows belonging to the first priority level are determined by an optimization method which minimizes the electrical flows as a function of the electrical flow measurements from step 3 and by putting implement the flow conservation model built in step 1.
- the electrical flows belonging to the first priority level are determined by a minimization of a function obtained by the flow conservation model, the minimization being constrained by the measurements.
- the optimization method can implement a linear programming algorithm, and/or a quadratic programming algorithm. These algorithms allow electrical flows to be determined precisely, robustly and quickly.
- Linear programming also called linear optimization, is a method for obtaining the best result in a mathematical model whose requirements are represented by linear relationships.
- Linear programming is a special case of mathematical programming (also called mathematical optimization). More formally, linear programming is a technique for optimizing a linear objective function, subject to equality constraints and of linear inequalities. Its feasible region is a convex polytope, which is a set defined as the intersection of a finite number of half-spaces, each of which is defined by a linear inequality.
- Quadratic programming is a process of solving certain mathematical optimization problems involving quadratic functions. More precisely, we seek to optimize (minimize or maximize) a multivariate quadratic function subject to linear constraints on the variables. Quadratic programming is a type of nonlinear programming.
- the optimization method can implement a linear programming algorithm. Furthermore, in the case where the linear programming algorithm determines a plurality of solutions, the optimization method can implement a quadratic programming algorithm. Thus, the quadratic programming method is only applied to the most complex optimizations, which promotes speed, and limits the processors as well as the computer memory necessary to determine the electrical flows. Thus, the process can be applied in real time.
- this quadratic programming algorithm can be constrained by a predefined electrical flow distribution rule.
- a rule for distributing electrical flows translates for components of the same priority level how the electrical flows are distributed between these components.
- a rule can apply when the energy community includes a producer system and two consumer systems of the same priority level, it then involves distributing the energy produced by the producer system between the two consumer systems .
- the distribution rule can in particular be chosen from a weighted distribution, a distribution proportional to electricity consumption, or a combination of the two.
- the optimization method can be constrained by the measured electrical flow obtained by an official (certified) measuring means.
- an official (certified) measuring means In other words, when the measured electrical flow is certified, this measurement serves as a constraint for the optimization method. In this way, the determined electrical flows conform to the measurement at the measurement location.
- this measurement can serve as a constraint for the optimization method.
- this uncertified measurement serves as a constraint for the optimization method.
- the determined electrical flows conform to the measurement at the measurement location.
- this measurement can be adjusted by the optimization method.
- an additional degree of freedom can be left to the optimization method, while respecting as much as possible what has been measured, to maintain good representativeness of the determined electrical flows.
- This problem can be solved using a standard linear programming algorithm.
- the above problem may not have solutions if the measurements are inconsistent with each other, and this is something very likely if the measurements are all independent from each other, due to measurement errors.
- the measurements, denoted y correspond to sums of certain energy flows and can be linked to the electrical flow vector x by a matrix M in the following way:
- E (p) is an identity matrix cut so as to retain only the electrical flow lines determined at lower priority levels.
- z (p-1) a vector of electrical flows determined at lower priority levels.
- step 4 for the first priority level, no electrical flow has been determined beforehand.
- L (p)T x is the cost function in the linear problem
- x (p) the set of electrical flows of priority level p and p indicates the optimization problem that can be solved by a linear programming algorithm of the priority level p.
- This problem is solved using a linear programming algorithm. If this problem has a unique solution, in particular if there is a number of authorized flows in accordance with the number of measurements available, the unique solution defines the electrical flows of the priority level p and we move directly to the next step with a priority level p+1 (step 5). If this problem has an infinity of solutions, in particular if there are too many flows authorized in relation to the number of measurements available (the problem is underdefined), we then apply a quadratic programming algorithm.
- the quadratic programming algorithm makes it possible to determine a single solution which ensures the proper functioning of the energy community, that is to say without choosing a solution among the infinity of solutions which can benefit certain components of the energy community. and disadvantage others.
- a weighted distribution rule which distributes energy according to predetermined weightings for each electrical flow of a priority level p.
- e Pi cj the distribution weighting for the flow F Pi ,cj and we can write optimization constraints:
- a proportional distribution rule also called prorata
- prorata which distributes energy in proportion to the consumption of each of the consuming systems
- L (p)T x is the cost function in the linear problem and P indicates the optimization problem that can be solved by a linear programming algorithm of priority level p.
- the optimization method makes it possible to determine the electrical flows belonging to the first prioritization level.
- the optimization method takes into account the electrical flows determined for the lower priority level(s) (for example for the second priority level, the optimization method takes into account the electrical flows determined for the first priority level, and for the third priority level, the optimization method takes into account the electrical flows determined for the first priority level and the second priority level).
- the method implements an iterative method which determines the electrical flows by priority level.
- the application of an iterative method according to an order of priority allows simple and rapid convergence towards a determination of electrical flows (taking into account the different constraints), which allows the application of the process in real time.
- the problems f ⁇ can be solved iteratively by increasing the priority level p, the quadratic programming algorithm being able to be applied only if the linear programming algorithm determines infinitely many solutions.

- the steps identical to Figure 1 are not redescribed.
- the method further comprises a step of CON control of the energy community as a function of the determined FeN electrical flows. For example, if energy consumption exceeds demand, certain components can be started to increase one-time energy production. Conversely, if energy production exceeds consumption, the surplus energy produced can be used to store energy, for example in batteries or in means of energy storage by compressed air or in storing water in hydroelectric dams.
