Conversely , a frequency higher than the nominal frequency, for example equal to 51, 52 or 53 Hz in Europe, is representative of an offer greater than the demand addressed to the network.
- the difference between the value of the current frequency and the nominal frequency quantifies the imbalance between supply and demand relative to the network.
- a difference of 2 Hz on an ilien network may represent an imbalance greater than 10 MW, or even 15 MW.
- An excessively large difference between the current frequency and the nominal frequency can also cause the collapse of the network.
- the DETEC detection module is also configured to count the electrical energy drawn by the EQi equipment for its operation over time. For example, it is configured to measure the electrical energy drawn by the equipment EQi for each time step of predetermined duration.
- the DETEC detection module is coupled to the planning module for the supply of data to the latter, in particular the electrical consumption of the EQi equipment.
- the planning module PLAN is configured to construct a planning of the operation of the cyclic electrical equipment defining for said cyclic electrical equipment at least an altered cycle phase with respect to the corresponding nominal phase. In addition, it is configured to trigger and / or implement this schedule.
- planning is meant here an operating diagram of the equipment EQi which diverges the equipment from its nominal operation.
- This planning is constructed from an estimate of the value of the characteristic quantity GCi of the cyclic electrical equipment relative to its setpoint value determined by the planning module. As described in more detail below, this estimate is made on the basis of a state variable representative of the progress of the current cycle phase and which constitutes an estimate of the relative value of the magnitude. characteristic with respect to the corresponding setpoint.
- the schedule is associated with an initial time corresponding to the planned start time for the implementation of the schedule.
- it comprises triggering (that is to say causing) the switching from the current nominal phase of the operating cycle to the next, or to a phase similar to this next phase, that is to say ie, corresponding to the same type of behavior with respect to the characteristic quantity of a freewheeling phase of the characteristic quantity and an active regulation phase of the characteristic quantity.
- phase similar to a second phase may differ from a second cycle phase as such in that the equipment does not draw electrical energy for its operation.
- the active control phase may correspond to a first nominal cycle phase.
- the nominal phase during which the implementation of the planning takes place is altered, particularly in terms of duration.
- the current phase is a first phase
- the planning results in an erasure of the equipment. It is noted that in the second phase thus triggered, the power supply of the equipment EQi in electrical energy is advantageously completely cut off.
- erasure is meant here a temporary regulation of the power supply of the EQi equipment considered to reduce consumption, this regulation corresponding here advantageously to an interruption of the power supply of the electrical power equipment.
- the scheduling module is configured to build and implement the schedule according to the value of a connection function denoted L (t).
- This function j (t) depends on the current phase and a state variable denoted E 0N (Î) for a first phase and E 0FF (Î) for a second phase.
- the state variables are representative of the progress of the corresponding phase as estimated by the planning module, for example expressed in percentages. They are representative of an estimate of the value of the characteristic quantity with respect to the corresponding reference value.
- the state variable is advantageously estimated at least from the end of the previous phase, the instant of which is determined by the DETEC detection module via the measurement of the electrical power drawn off by the equipment, as well as from T 0N for the first phase and T 0FF for the second phase.
- the beginning of a first phase is detectable by a sudden substantial increase in the consumption of the equipment.
- a sharp drop in consumption indicates the beginning of a second phase.
- T 0N and T 0FF are determined by learning the operation of the equipment operated by the learning module, as described below.
- the dependence of the state variable with respect to time is constructed to model the variation of the characteristic quantity with respect to the corresponding reference value during the phase considered.
- the variable E 0N (1) is advantageously increasing.
- it varies from a minimum value, for example 0%, to the instant 1 ⁇ 23 ⁇ 4 to a maximum value, for example 100%, at time t 0 FFj (which is equal to or substantially equal to t 0 Nj + ToN, for example on average).
- the variation between these values is, for example, linear.
- This configuration is particularly advantageous in terms of computing power required.
- other configurations of variation of this variable with respect to t are possible.
- the variation of the state variable is of exponential configuration, the values taken at the initial and final instants remaining for example the same.
- the variable E OFF (Î) is advantageously increasing. It varies from a minimum value, for example 0%, at time t 0 FFj to a maximum value, for example 100%, at the moment toNj + i (which is equal to or substantially equal to Î OFFJ + T OFF , for example on average).
- the variation between these values is, for example, linear.
- other configurations of variation of this variable with respect to t are possible.
- the variation of the state variable is of exponential configuration, the values taken at the initial and final instants remaining for example the same.
- the function j (t) has two configurations respectively associated with one and the other of the nominal phases. In other words, its variation vis-à-vis E 0N is distinct from its variation with respect to E 0FF -
- the function f has a minimum value fi, m mi and a maximum value fi, max i different from each other. They are preferably strictly lower than the nominal frequency of the network.
- These minimum and maximum values are, for example, predefined. They are for example predefined as a function of the network R, a given network being capable of having a frequency having a variation amplitude very different from that of another network. For example, these values are respectively 46 Hz and 49 Hz for a nominal frequency of 50 Hz. In other configurations, these values are closer to the nominal frequency, and differ from the nominal frequency of a magnitude of the order. tenth of a hertz rather than hertz.
- the function fi is for example increasing for the first phase. For example, is the minimum value fi, m mi for the minimum value of E ON (Î), and the maximum value fi, max i for the maximum value of E 0N (t).
- i (t) has the minimum value for E 0 N (t) ranging from its minimum value (for example 0%>) to a predetermined value greater than this minimum value.
- This predetermined value is for example of the order of 20%> as in FIG. 5A.
- fi (t) varies for example linearly between this predetermined value of EQ N (Î) and the maximum value of E 0N (for example 100%). Note that alternatively, the minimum value of fi is taken only for a single value of E 0N (t).
- fi has, for the second phase, a minimum value fi, m m2 and a maximum value f1, max2 different from each other.
- These minimum and maximum values are preferably strictly greater than the nominal frequency. They are for example predefined according to the network. For example, they respectively correspond to 51 Hz and 55 Hz for a nominal frequency of 50 Hz. As before, however, they are alternatively closer to this nominal frequency, and deviate from a magnitude of the order of one tenth of hertz.
- the function f it) is advantageously decreasing for the second phase.
- the maximum value fi, maX 2 is for example taken for minimal EOFFO.
- the minimum value fi, m m2 is advantageously taken for EOFF (Î) maximal.
- fi (t) has (for the second phase) the maximum value for EOFF allant ranging from its minimum value (for example 0%) to a predetermined value greater than this minimum value (for example 20% as in FIG. 5B).
- This predetermined value is a priori decorrelated from the predetermined value of E 0 N (1) until fi is the minimum value in first phase.
- fi (t) varies for example linearly between this predetermined value of EOFF (Î) and the maximum value (for example 100%).
- Î EOFF
- f it is advantageously configured to take one of two values, high for one and low for the other. These values are for example 1 and 0.
- One of the values is taken when a given condition relating to a magnitude representative of the difference between fi (t) and f gr id (t) is satisfied, and the other value is taken. if this condition is not verified.
- This condition is advantageously defined from the difference between the values fi (t) and f gr id (t) at the instant considered and advantageously corresponds to the comparison between the difference itself and 0.
- condition itself or the criterion determining whether this condition is considered verified may differ depending on the current phase. For example, in the example of the Figures, if f is constructed to take the high value if the difference between fi (t) and f gr id (t) is negative regardless of the current phase and its low value. conversely, then, at nominal network frequency, L will take the high value in the first phase and its low value in the second phase without this being detected as meaning that a planning is required.
- construction of f can be adjusted according to the current phase so that a given value is associated with a lack of planning, and the other value is the opposite trigger of a planning.
- the planning module Based on at least the value of L and the nature of the current phase, the planning module detects that a planning is to be implemented at a given moment and determines the nature of this planning (which is in practice a erasure in case of first phase in progress, and an early start in case of second phase in progress).
- this detection that a planning is to implement optionally includes an additional condition relating to the retention in time of L to a given value, for example over a predetermined period of time of a chosen duration.
- the given instant is for example the moment corresponding to the moment of the detection of the change in the value of L indicative of the fact that a planning is required.
- this moment is deported in time, for example of a predetermined duration.
- the MODi module and in particular the scheduling module, is configured to trigger the implementation of the schedule defined at the associated time.
- the modalities of this trigger vary according to the nature of the planning envisaged.
- the module MODi is configured to control the disconnection of the equipment EQi from the network via the disconnection module REL.
- the module MODi is advantageously configured to send to the equipment EQi a corresponding signal whose reception by the equipment EQi results in the start of the active regulation of the characteristic quantity via a power consumption.
- the module MODi is integrated with the equipment EQi and is adapted to communicate with a control device of the components configured to regulate the characteristic quantity (for example in particular of the compressor COMP in the case of 'cold generating equipment).
- a MODi module according to the first configuration is also possible, in which case it is further configured to send signals of this type to this control device (for example via a wired communication means or not).
- this switch is triggered in response to the changeover of the value of L (t) from its current value to its other value in a two-valued configuration. For example, if the schedule is configured to be triggered in response to the fact that L (t) is set to its high value, and the schedule corresponds to an erasure, then the erasure ends when L (t) returns to its low value. , which is for example the case if the frequency of the network returns to the nominal value.
- This return to nominal operation is optionally triggered by the MODi module, which sends a signal to this effect to the equipment and / or connects or disconnects the equipment to the network via the REL module.
- this switchover is triggered after a predetermined period of time.
- this time is for example determined as a function of the value of T 0FF and the state variable E OEF (Î) at the time of implementation of the planning.
- this time is determined randomly, for example under the constraint of intervening in a given time interval.
- this tripping of the nominal operation is advantageously implemented by the module MODi, for example according to the same modalities as above.
- this switchover is made in response to crossing or reaching by the characteristic quantity of a threshold value (which may correspond to a setpoint value implemented during a nominal phase).
- this modality is implemented by the equipment itself, which spontaneously returns to its nominal operation.
- this return is authorized by the MODi module, in particular via the reconnection of the equipment to the network R by the REL disconnection module.
- this switchover is made in response to crossing or reaching by the state variable associated with the nominal phase or the analogous phase defined by the planning of a threshold value.
- the MODi module tracks the state variable E OFF (Î) as if a second phase was in progress taking into account the value of the state variable E ON (Î) in the first phase during which the erasure occurred.
- E 0N (Î) is performed at early start taking into account the value of E 0FF (Î) at the time of early start.
- these conditions are used in a combined manner, and each form one of the conditions jointly employed.
- the switching is for example performed on verification of any number of these conditions, between one and the number of conditions used. For example, this switch is made in response when a number is verified.
- one or more are defined as critical and must then be checked for the switchover to be made.
- the MODi module is configured to reconnect the equipment to the network via the disconnection module, which is controlled for closing the conductors.
- the equipment then returns in a first phase in response to the achievement of the corresponding instruction by the characteristic quantity.
- the MODi module forces the start of a first phase by sending a command adapted for this purpose to the EQI equipment, or to the control device of the chain of equipment in charge of the regulation of the magnitude feature.
- the module MODi is adapted to control the electrical connection of the equipment EQi to a backup electrical energy storage device coupled to the equipment EQi and to the module MODi, for example via the control of the REL disconnection module which is then adapted to perform this selective connection / disconnection.
- This connection is made in conjunction with that of the equipment to the network, or instead of it.
- the equipment For an early start (that is to say if a phase of regulation of the characteristic quantity is in progress due to an anticipated start), the equipment returns to the second phase once the characteristic quantity has reached the value of setpoint of the corresponding phase.
- the MODi module causes the end of the active regulation of the characteristic quantity by disconnecting the equipment from the network via the REL disconnection module.
- the module prohibits this end of regulation for a predetermined period of time after starting the compressor COMP.
- this lapse of time presents a duration corresponding to the duration over which the function f has a zero value for the first phase (which corresponds for example to 20% of the value of T ON ) -
- the APP training module is configured to generate training data based on the nominal operation of the EQi equipment.
- This learning data includes the quantities T 0N and T 0FF -
- these data also include a characterization of the variation of the characteristic quantity during the two nominal cycle phases.
- the module APP detects the attainment of GCimin when the equipment EQi passes from its first phase its second phase and that the power demand of the equipment EQi on the network s is found to be reduced by a value corresponding to all or part of the consumption of the EQi equipment. Similarly, reaching GCimax is detected when the consumption of the equipment EQi increases by a value corresponding to all or part of the consumption of the equipment EQi.
- the duration of the current phase, T 0N G) or T OFF G is determined by the APP module from previous nominal cycles (which may have been the seat of a disturbance).
- the duration of training makes it possible to increase the statistical knowledge of the nominal cycles for a given equipment EQi and makes it possible to improve the taking into account of the disturbed cycles (for example following a door opening for a refrigerator and / or freezer).
- T 0N and T 0FF may vary over time. More specifically, they are advantageously constructed to depend on the time of the day, the day of the week, the month in question, and / or the season in question. In particular, these quantities are likely to vary because of the temperature outside the equipment EQi, which is influenced by the time of day and the season considered, because of the actions of users, which tend to be more frequent day that night and days not worked, etc.
- this initial characterization defines a profile of variation of the magnitude GCi of exponential type for each phase.
- This characterization is then adjusted, in particular in terms of parameterization, to take account of the determined quantities, such as T ON and T 0FF , for example so that the extrema of this characterization coincide temporally with the beginning and end of phase.
- the characterization of the variation of the characteristic quantity is used to adjust the configuration of the variation of the state variables as a function of time. In the absence of such an adjustment, the state variables have, for example, a predetermined predetermined configuration.
- a park management method P will now be described with reference to the figures, particularly in FIG. 6, in particular from the perspective of a given equipment EQi and the associated module MODi.
- the module MODi in particular the detection module DETEC and the learning module APP, collects data on the nominal operation of the equipment EQi, and in particular so that the module of APP learning determines the values of the quantities T ON and T 0FF and, advantageously, the characterization of the variation of the characteristic quantity GCi during the phases of the nominal cycle, advantageously used for the construction of the variations of the state variables E 0N and E 0FF -
- the DETEC detection module tracks the frequency of the network, and provides this information to the planning module PLAN. It tracks the value of the L (t) function over time, as described above. The values followed are for example determined at a regular frequency. In addition, advantageously, this monitoring continues throughout the operation of the EQi equipment once the SI stage completed.
- the function L (t) takes a value triggering the construction and implementation of a planning of the operation of the equipment EQi at the initial time associated.
- this schedule is an erase, the equipment being previously in the first phase.
- this planning is an early start of a first phase, the equipment being previously in the second phase.
- Step S4 the equipment EQi returns to its nominal operating mode, optionally by triggering or authorization of this return by the MODi module. This is done in response to the verification of the associated condition (s) described above. Steps S3 and S4 are for example repeated in time, the steps S3 occurring in response to changes in the value of the function L over time representative of the conditions for triggering an adjustment of the operation of the equipment EQi .
- the invention has several advantages. Firstly, it makes it possible to distribute the disconnections of the equipment of the park in an equitable manner and without affecting their functioning insofar as it proceeds on the basis of an evaluation of their current state to determine if this state is compatible with a planning to better control the consumption of these equipment in view of the state of the network.
- the configuration of the function L makes it possible to favor the application of an operation planning, in particular of an erasure, to the equipment that it does not disturb substantially, and conversely to limit the application of these schedules to equipment in such a state that planning could affect their operation (for example by promoting the wear of their component and thus degrading their service life).
- the invention proceeds without exchange of state data between the equipment and the module MODi, which makes it easier and more immediate implementation.
- the possible plans are varied, so that the invention is a powerful tool for adjusting the consumption of a fleet of electrical equipment to the situation of the power grid supplying them.
- the function f associated with the function L may also depend on the reception of an external control signal supplied to the module MODi, for example by a remote device.
- This signal is for example provided by PLC technology.
- the function f is for example constructed to take a given value in response to the receipt of this command, a value triggering the planning and its implementation.
- the return to the nominal operation is for example triggered by an external end of planning signal, or on the basis of one, more or all of the conditions described above. Note that this signal can be decorrelated from the value of the frequency of the network.
- At least one MODi module is coupled to a backup electric energy storage device that is adapted to electrically connected to the equipment EQi, for example via the REL disconnection module.
- This auxiliary device is advantageously used as a source of electrical energy for the operation of the equipment EQi in place of the network (or in conjunction with it), so as to limit the energy withdrawn from the network. This is for example implemented in the case where the frequency of the network is lower than the nominal frequency, but a control phase of the characteristic quantity must nevertheless be implemented by the equipment (for example following an erasure ).
- the MODi module then commands the REL disconnection module the connection of the equipment EQi to the backup storage device.
- the MODi module comprises a human-machine interface allowing a user to enter at least one command taken into account in the operation of the MODi module.
- the human-machine interface is suitable for allow the user to tell the MODi module that the implementation of schedules is not allowed. This input is for example carried out via one or more buttons, optionally combined with a display in the form of a tactile graphic interface.
- any indicator other than the network frequency and indicative of an imbalance between the supply and the demand on the network R can be used, possibly jointly with this frequency, such as for example one or more voltages supplied. by the network, or a gradient of the frequency and / or a gradient of this or these voltages.
- the frequency of the network is particularly advantageous.
- the method comprises a step of communicating the MODi module with a remote device, such as a remote platform.
- a remote device such as a remote platform.
- This communication is for example provided for the initial activation of MODi module, for example via a key exchange.
- the method comprises the exchange of information between the module MODi and another equipment, for example remote or temporarily coupled to the module MODi.
- Such an exchange is for example provided for updating the network frequency values used, and / or for the transmission of information to an operator of the network, such as diagnostic or performance information.
- this exchange is planned for the MODi module to declare itself active with a remote platform.
- the exchange of information is unidirectional, the information being sent by the module MODi to this center.
- this exchange is punctual. For example, it is done on a regular basis.
- an EQi equipment can be associated with several GCi characteristic quantities.
- the equipment then comprises respective equipment chains associated with the regulation of one of the magnitudes GCi, for example two separate cooling circuits, these chains being independent of one another.
- an equipment can be adapted to present a cut operation in independent cyclic sub-operations in terms of power consumption, each sub-operation for the regulation of one of the characteristic quantities GCi.
- the equipment is associated with a MODi module, or a MODi module for each characteristic quantity that it is configured to regulate.
- this or these modules are then integrated into the equipment, and are designed to operate as described above, preferably via an interaction with the control devices of these equipment chains, for the implementation of the invention.
- the magnitude representative of an estimate of the value of the characteristic quantity of the cyclic electrical equipment relative to the reference value of the current phase can correspond to a state of progress variable during a phase of a cycle.
- said representative magnitude may take the form of a percentage applied to a characteristic quantity.
- the temperature usually changes upwards or downwards, during a phase of a cycle, from an initial temperature T init up to a set temperature T cons .
- the operating schedule may comprise, for example, at least one altered cycle when said quantity is between X% and Y%, where the values of X and Y are for example dependent on the nature of the current cycle (active cooling or standby) and under the condition that a balance (or on the contrary an imbalance) is detected on the network.
- the altered cycle can correspond to the transition from the nominal phase of active regulation of the temperature to the passive nominal phase (absence of regulation of the temperature) when the evolution of the temperature reaches at least 80% of the cooling of T init to T cons and an imbalance on the network is found.
- the power consumption is stopped early, which helps to reduce the imbalance on the network while having a limited impact for the user: a cooling of 80% of the usual cooling is sufficient to ensure a desired temperature for a time thanks to the thermal inertia.
- the altered cycle may correspond to the early activation of the active regulation phase when the temperature evolution reaches at least 50%> of the warming from T init to T cons and no imbalance on the network is found.
- the active phase is triggered by anticipation.
- the power consumption is advanced over time, which contributes to reducing the risk of a subsequent imbalance on the network.
- the durations of each cycle can be reduced compared to their nominal duration in order to shift in time the phases during which the equipment consumes energy on the network.
- the durations flowing between the instants T 0N and T 0FF (and between T 0FF and T 0N ) are reduced for the equipment with respect to the known nominal durations.
- this tends to reduce the magnitude of the load peaks on the network by shifting the consumption in time (before and after peak loads). Note that it is not imperative to monitor directly and continuously the temperature (by sensors) but that an estimate of the evolution between T init and T cons , for example on the basis of preliminary observations, can to be sufficient.
