Abstract
The present invention relates to a method for directional transmission of power in the form of energy packets via a transmission network. The power to be transmitted is adjustable at at least one location x of each edge by a data and computer network. A data packet is biuniquely assigned to each energy packet, which data packet is formed in a control instance of the data and computer network by means of predictions. This data packet describes an optimized transport path via which optimized transport path a source transmits the physical power in a fixed transmission period T to a load for partial demand coverage. Furthermore, the data packet describes the power class of the energy packet, wherein this power class is defined by the temporal course of a nominal power P.sub.nom(t) determined by predictions and by a remainder R(t) in the transmission period determined by a function of an uncertainty of the predictions. For the transmission of the energy packet, the transmitted power equal to P.sub.nom(t) plus a fraction of R(t) is set for each point in time t within T at at least one location x of each edge of the transport path.

[0377] To cover the demand of 7.100, a second energy packet E.sub.2 must be transmitted simultaneously in this example. The routing procedure has booked the solar generator 6.200 and the transport path 102.000 for this purpose; the transport graph 110.000 is formed from the union of the two transport paths 101.000 and 102.000.

[0381]
[0382] The bidirectional power controller 2.300 is connected to an actuator 2.400. The sensors 2.310 and 2.320 as well as the actuator 2.400 are equipped with a connection for transmitting data to the corresponding CPS 205.000. The CPS in turn is equipped with a connection to 200.000 for data exchange. Furthermore, the QFC has a buffer on each of its edges 2.110 and 2.120 to compensate for small deviations or to implement quantisation. In one embodiment, in order to transmit an energy packet either via an edge connected to port a) or to port b), the physical power is set by the power controller 2.300 at the corresponding location of the edges, i.e. the connection point to the corresponding port. This is done by the corresponding control instance carrying out the corresponding setting by means of the actuator. In one embodiment, this is done by transmitting the real-time data packets assigned to the energy packet to be transmitted from the corresponding control instance 220.000 to 205.000 via the data connection from 205.000 to 200.000 for setting. There, the corresponding setting data for the setting device is then calculated and entered into a queue system. For the corresponding time cycles, the setting device 2.400 then takes these values from the queue and sets the power at the power controller 2.300 depending on the flow direction. The data determined by the sensors is transferred to 205.000 and, if necessary, already subjected to processing there, for example by forming moving average values in one embodiment. These values are then transmitted to 220.000 for further processing, e.g. for real-time predictions, but also for early fault detection. In another embodiment, the setting parameters for setting the physical power are already calculated by the corresponding control instance and transferred to 205.000 for setting.
[0383] In the following, we will explain the method according to the invention with the help of
[0384] According to
[0385] For clarification, we simplify our example even further and assume that the measured values for these comparison periods satisfy a Gaussian distribution and have a constant expected value, mean value, over T of <p.sub.Bed(t)>:=<p.sub.Be>=100 kW, ∀t from T, with a constant standard deviation of σ=5%. Thus, in the past, about 99.7% of the values of the power consumption of load 7.100 were in the interval from
−3σ to +3σ and fluctuated within the limits of 85 kW to 115 kW. It is therefore obvious to take these data for the demand prediction of the corresponding transmission period for the same seasonal period. To simplify matters, we further assume in our example that the supply prediction for T, due to seasonally largely constant wind conditions, results in a mean value for the source of a predicted power <p.sub.Ein(t) >=110 kW, ∀t from T. For the standard deviation of the supply prediction, we assume that this is also σ=5%. Based on these predictions, the routing procedure now forms the demand, supply, coverage and loss data packet. The routing procedure checks whether E′.sub.Ein.sub.
[0386] Furthermore, it is obvious to determine the remainder R.sub.Bed(t) of the power class of the demand data packet to be R.sub.Bed(t)=ƒ.sub.Prognose.sub.
leading to ƒ.sub.C(R)≈1.9.Math.R.sub.E. One task of the demand prediction is to predict, in the case that the load has a storage in its analogue part, whether this storage has the potential to absorb or release a maximum power of C(t), ∀t, in order to be able to compensate for the difference δ(t). In the event that the load does not have this potential, the demand prediction is used to instruct the routing procedure to determine a transport graph extended by compensation. In case that the load 7.100 is equipped with a storage in its analogue electrical part that can deliver or receive C(t), the difference δ(t) is compensated by a suitable control, e.g. by the condition P.sub.Bedarf+p.sub.ein(t)+p.sub.Speicher(t)=0, ∀t from T. This is, according to claim 1, the simplest embodiment of the invention, so that by transferring the energy packet of 6.100 via 101.000, the demand of 7.100 is met.
[0387] At this point we would like to note that the improvement in prediction accuracy is immediately reflected in the required storage capacity. For example, if σ can be reduced from 5% to 2.5%. Then C=2R decreases from 30 kW to 15 kW and over the whole period T the maximum energy that must be able to be absorbed or delivered by the storage decreases from 30 kW T to 15 kW T. For this reason, between the reservation and the final booking, further predictions are carried out with ever decreasing intervals between the prediction and the execution time, so that the prediction uncertainty becomes smaller. Reserved but then no longer required capacities are then released again. The sequence of predictions after booking ends with the sequence of real-time predictions. Here, too, capacities that are no longer required are released immediately if they are no longer needed due to the more accurate prediction. If the storage does not have a suitable storage, then an optimally determined extended transport graph is determined by the routing procedure. In our example,
[0388] In case that the source feeds in the physical power p.sub.φ.sup.Ein(x.sub.p, t)=p.sub.φ.sup.Bed(x.sub.p, t)+δ(t), the QFC node 2.410, which is connected on one side to the demand node 1.900 and on the other side to the compensation path 106.000, sets the power δ(t) and the QFC 2.420, which is connected on one side to the compensation path 106.000 and on the other side to the storage as compensation node 4.400, sets the power supplied to 4.400 to {tilde over (δ)}(t)=δ(t)−δ.sub.ν(t). Here δ.sub.ν(t) is the loss that occurs during the transmission of δ(t) via 106,000. In a case wherein p.sub.φ.sup.Ein(x.sub.p, t)=p.sub.φ.sup.Bed(x.sub.p, t)−δ(t), the QFC 2.420 sets the power {tilde over (δ)}(t)=δ(t)+δ.sub.ν(t) in 106.000 and δ(t) is then supplied to demand node 1.900 via QFC 2.410. Since the demand node is an ohm node, taking into account the direction of flow, it follows that the physical power from the demand QFC at the location x.sub.p of the demand edge can be set exactly equal to the demand. To determine δ(t) and δ(t), p.sub.φ.sup.Ein(x.sub.p, t) and ρ.sub.φ.sup.Bed(x.sub.p, t) are determined by predictions, and real-time predictions, respectively. Thus, packets with the power class {p.sub.nom(t)=0, R(t)=C(t),T} are transmitted on the compensation path. By means of a conversion, this then corresponds to the fact that the physical power set for x.sub.p can be represented as the sum of the nominal power of the transmitted energy packet E and a compensation power δ′(t):
p.sub.φ(x.sub.p,t)=p.sub.nom(t)+δ′(t).
[0389] In our example, we had assumed, on the one hand, that both the supply and the demand prediction have the same percentage standard deviation of 5% and, on the other hand, that the function ƒ.sub.Prognose is the multiplication by the factor 3.
[0390] In the following consideration, we want to use the example to show that the function for determining the remainder takes place on a case-by-case basis. To explain this, we will now consider an example, wherein an analogue storage connected to load 7.100 cannot completely provide C(t)=2R.sub.Bed=30 kW. However, the demand prediction shows that the analogue storage can only take in or deliver 10 kW for each point in time of the transmission period. For simplicity, we neglect the losses. In this case, a demand data packet with a remainder R′.sub.Bed(t)=⅔R.sub.Ein(t)=10 kW can be formed based on the demand prediction. The nominal power remains constant and equal to 100 kW over T. Accordingly, the load then requests that the routing determines a transport graph 120.000 extended by compensation. The compensation node must then have a maximum compensation power of C(t)=2, R′.sub.Bed (t). By transmitting the thus modified energy packet E with power class {100 kW, 10 kW, T}, the physical power injected by the source varies in the interval from −2σ to +2α, whereby, on the other hand, the demand of the load varies in the range from −3σ to +3σ. This means that in about 95% of the cases, a possible difference between the physical power injected and the physical power required by the load 7.100 is compensated by the compensation node of 120.000. Thus, via the energy packet and the compensation packet of compensation node 4.400, a maximum physical power p.sub.φ(x.sub.p, t)=p.sub.nom(t)+R′.sub.Bed(t)=110 kW can be injected into the demand edge of load 7.100. In case the demand is e.g. in the interval between +2σ and +3σ, the missing difference is then compensated by the analogue storage. If, for example, the demand is 115 kW, the missing 5 kW in the analogue part is compensated via the control of the analogue storage. In this case, the choice of the new remainder for the demand data packet can simply be justified by the fact that the use of the analogue storage reduces the purchase price for the energy packet and for the compensation.
[0391] It is essential that the sources and loads have concluded a generally valid agreement for the transfer of energy packets. In our example, we assume that the source and the load have committed themselves according to this agreement that in 99.7% of the points in time of a transmission period both injected and absorbed physical power is an element of the agreed energy packet.
[0392] In our example, the source 6.100 can only supply a physical power that is an element of the power class (100 kW, 10 kW, T) of the modified energy packet in approx. 95% of the points in time. At the remaining times, the physical power of the source is in the |2σ| to β3σ| range and there is either a shortage ρ.sup.+, the power is less than 90 kW, e.g. it is 85 kW, or there is an excess ρ.sup.−, the power of 6.100 is greater than 110 kW, e.g. it is 125 kW. To compensate for this gap, the source needs an additional maximum compensating power ID(t)I of 5 kW. Since D(t)=ƒ.sub.D(R(t)) and R(t)=R′.sub.Bed(t) for the modified energy packet, the function ƒ.sub.D is determined as
R.sub.Ein(t). Within the framework of the supply prediction, in the case that the source has a connected analogue storage unit, it is also predicted which D(t) the connected analogue storage can absorb or deliver. If the supply prediction shows that 6.100 has such an analogue storage system that can absorb or deliver a physical power up to the maximum balancing power of D(t)=5 kW for each point in time within the transmission period, then the balancing is carried out by this storage system. This means that both a shortage ρ.sup.+(t) and an excess ρ.sup.−(t) are compensated by the storage unit by means of a corresponding control, analogous to compensation.
[0393] If a compensation via an analogue storage is only partially possible or not possible at all, the supply prediction requests an optimised transport graph from the routing procedure, as shown in
[0394] Balancing packets with the power class {0, D(t), T} are then transmitted on the balancing path. At the transmission time, the modified energy packet is then transmitted via the transport path 101.000 and the physical power, corresponding to the flow direction at the two QFCs of the balancing path, is set so that it is either equal to ρ.sup.+(t) or ρ.sup.−(t)
[0395] At this point we want to note that both the supply and demand predictions and the derived formation of the supply, demand, coverage and loss data packets are part of the iterative routing procedure. In addition to the ratios of the expected values z of the demand and supply predictions to each other, the ratio of the variances or standard deviations of these predictions to each other also plays a decisive role in determining the power class of an energy packet to be transmitted using the compensation and balancing mechanism.
[0396] To show the variety of possibilities for determining the energy packet to be transferred, we now modify our example slightly. We assume that the transmission period falls in a period of very stable wind conditions, so that the standard deviation, in contrast to the one considered before, is only half, i.e. σ′=σ.sub.Ein=2.5% and thus R.sub.Ein=3.Math.σ′.Math.<p.sub.Ein(t)>=7.5 kW. If we again neglect the losses for the sake of simplicity, we could set the coverage packet E.sub.D and thus the energy packet E to be transmitted equal to the demand data packet E.sub.Bed with the power class (100 kW, 15 kW, T). We further assume that the load 7.100 has an analogue storage to compensate for the difference C(t)=2.Math.R.sub.Bed between the supplied and required power. Since the physical power supplied by source 6.100 is an element of E.sub.Bed due to the smaller variation by half, the source 6.100 can meet the demand of load 7.100 by transferring this energy pact E=E.sub.D=E.sub.Bed, according to the agreement. But the choice of this packet has the consequence that an unnecessarily large amount of transmission capacity, twice as much as necessary, must be reserved for the transmission of the energy packet. An alternative way to define an energy packet is to set the remainder R.sub.E of the energy packet equal to R.sub.Ein=7.5 kW. In this way, only the transmission capacity that is really needed must be reserved. However, in order to compensate a possible difference, C(t)=ƒ.sub.c(R.sub.Bed) must be set. Since R.sub.Bed can again be expressed as a function of R, in this case, ƒ.sub.c is also a function of R. Since we have assumed that the storage can compensate for this C(t), this energy packet together with 101.000 is determined as the optimal transport graph or transport path due to the transmission costs lowered by half. The example shows that a transport path TP(E, Q, S, T) always consists of a path P in the transmission network that connects the source Q with the load S and an energy packet E, defined by its power class {p.sub.nom(t), R(t),T}.
[0397] Finally, let us briefly look at the transmission of the energy packet and the assigned compensation and balancing packets. For this purpose, we assume that all quantities are “quantised”. For this we assume that the duration DT=100 dt and the duration of all real-time prediction periods is DT.sub.RT=dt. Thus T can be covered by the real-time prediction periods Th.sub.r with l=1 to 100 without intersections. The corresponding real-time predictions are carried out at the real-time prediction periods t.sub.l.sup.000. Here t.sub.l.sup.000 is chosen so that for the execution time t.sub.0=t.sub.1.sup.000+dt and for t.sub.l.sup.000=t.sub.1.sup.000+(l−1).Math.dt. According to the real-time predictions, the nominal powers of the corresponding real-time packets are then formed, so that for the nominal powers of the real-time energy packets are determined to p.sub.nomRT(x.sub.TP,t)=n.sub.ij.sup.TP.Math.dp, of the real-time compensation packets are determined to p.sub.nomRT(x.sub.TP, t)=n.sub.ir.sup.kP.Math.dp, and of the realtime compensation packets are determined to p.sub.nomRT.sup.Aus(x.sub.AP, t)=n.sub.is.sup.AP.Math.dp. Here n.sub.ij.sup.TP, n.sub.ir.sup.kP and n.sub.is.sup.AP are integers greater than or equal to zero, dp is the elementary power, the so-called “power quantum” and dt the “time quantum”. The index j designates the location x of the edge e.sub.j.sup.TP of the transport path TP 101.000. Correspondingly, the indices r and s are to be understood for the edges of the compensation path KP 106.000 and the compensation path AP 108.000. The index i denotes the “quantised” point in time associated with the point in time t with (i−1)≤t≤i.Math.dt.
[0398] In our example, according to the sequence of real-time predictions for the sequence of T.sub.RT.sup.l, the values n.sub.ij.sup.TP, n.sub.ir.sup.kP and n.sub.is.sup.AP are determined by the corresponding control instances 220.000 and transmitted via the corresponding data connections to the CPS 205.000 of the corresponding QFCs 2.000, as in
[0399] Finally, we would like to note that with the advances in quantum computing, at least one node of the data and computer network can be a quantum computer. Due to the superior computational power of the quantum computer and the advances in the models for accurate long-term weather prediction that can be run alongside the routing procedure on this quantum computer, a highly dynamic and accurate regenerative hybrid energy supply system can thus be implemented that is superior to today's solutions.
