Abstract

A system provides distribution of electrical power generated by means of a private network over stakeholders in the private network. The energy may be distributed based on demand and past use; based on the past use, energy is distributed such that over time, energy is made available evenly over the stakeholders; such may depend on a particular share in the property of each stakeholder. The stakeholders may be apartments or other entities like small companies. Each stakeholder may have its own controller to determine local demand and send an energy request to a central distribution unit. The central distribution unit distributes the energy based on the distribution rule; if the stakeholder requires more energy, the controller may retrieve such electrical energy from another source, like a public power grid.

Description

P128320NL00 Title: System for distribution of electrical power on a local power grid
TECHNICAL FIELD The various aspects and implementations thereof relate to a system and method for distribution of locally generated power over a multitude of local entities.
BACKGROUND With a call for sustainable energy generation, energy is generated locally. The energy may be generated using solar power, wind power, hydropower, other, or a combination thereof. The electrical energy thus generated may be provided to local entities, like households and companies.
SUMMARY Local power generation may or may not fulfill local energy demand by the local entities or local dwellings. With local power generation, there may be a need for a method and/or device for distribution of the locally available power over the residencies.
A first aspect provides a system for distribution of electrical power from a first electrical power source over a first residency and a second residency. The system comprises a distribution module and a central control unit. The distribution module comprises power inlet for receiving electrical power from the first electrical power source, a first power outlet arranged to provide electrical power to the first residency and a second power outlet arranged to provide electrical power to the second residency. The distribution module is arranged to distribute the electrical power from the first source over the first residency and the second residency. The central control unit is arranged to monitor a first amount of power received from first electrical power source and provided to the first residency and a second amount of power received from first electrical power source and provided to the second residency over a period of time in order to collect monitoring data and control the distribution of the electrical power from the first source over the first residency and the second residency by the distribution module based on the monitoring data.
This aspect allows locally generated power to be distributed over multiple residencies participating in the local grid, based on a longer term scheme for providing particular shares of the locally generated power (electrical energy) over the residencies. It may be that a particular first residency has not consumed a lot of energy over a first particular amount of time, but has particular first rights to local power. And in that scenario, a second residency has used a significant amount of locally generated electrical power over the first amount of time. If the first residency has more energy rights left than the second residency at a particular moment in time, the distribution module may be controlled to first meet the demand of the first residency and subsequently provide any power that may be left to the second residency.
In one implementation, the system further comprises a first residency control unit and a second residency control unit. The first residency control unit comprises a first power inlet for receiving power from the distribution module, a second power inlet for receiving power from a second electrical power source, a power outlet for delivering electrical power to the residency, a residency power detection unit arranged to detect power demand at the power outlet and power supply received at the first power inlet and a control unit to arranged to demand electrical power from the second power inlet if power demanded at the power outlet exceeds the power received at the first power inlet. The second residency control unit comprises a first power inlet for receiving power from the distribution module, a second power inlet for receiving power from a second electrical power source, a power outlet for delivering electrical power to the residency a residency power detection unit arranged to detect power demand at the power outlet and power supply received at the first power inlet and a control unit arranged to demand electrical power from the second power inlet if power demanded at the power outlet exceeds the power received at the first power inlet.
This implementation allows for a backup option if the locally generated energy or other energy provided by the first electrical power source 1s insufficient to provide the two residencies with the electrical power they require.
In a further implementation, the central control unit is arranged to control the distribution of the electrical power from the first source over the first residency and the second residency by the distribution module by controlling the distribution module in supplying electrical power to the first residency and the second residency. In this implementation, the distribution of electrical energy is a push model, controlled by the distribution model as a central referee, under control of the central control unit.
In another implementation, the central control unit is arranged to control the distribution of the electrical power from the first source over the first residency and the second residency by the distribution module by controlling power demand of power from the distribution module by the first residency control unit and the second residency control unit. In this implementation, the central control unit controls the residency control unit to demand energy from the distribution module in a pull model, by demanding the power that the central control unit has determined the residencies are entitles to.
In yet a further implementation, the distribution module comprises a distribution power sensing unit arranged to sense a first amount of power provided to the first residency, sense a second amount of power provided to the second residency and provide power consumption data on the first amount and the second amount to the central control unit; in this implementation, the central control unit is arranged to monitor power provided to the first residency and the second residency based on the consumption data. This implementation allows for central collection of consumption data.
In yet another implementation, the first residency control unit comprises a first residency power sensing unit arranged to sense a first amount of power received via the first power inlet of the first residency control unit and to provide first power consumption data on the first amount to the central control unit, the second residency control unit comprises a second residency power sensing unit arranged to sense a second amount of power received via the first power inlet of the second residency control unit and to provide second power consumption data on the second amount to the central control unit and the central control unit 1s arranged to monitor power provided to the first residency and the second residency based on the first consumption data and the second consumption data. This implementation provides an alternative or additional option for collecting consumption data.
In again a further implementation, the control unit is arranged to sense a first power demand demanded by the first residency and sense a second power demand demanded by the second residency and prioritise supply of electrical power to the first residency over the supply of electrical power to the second residency if power received from the first energy source is less than the total of the first power demand and the second power demand. This particular implementation may be suitable to provide equitable amounts of energy from the second source to each of the residencies.
Again another implementation comprises a battery module, and the distribution module further comprises a battery connector arranged to provide electrical power to or receive electrical power from the battery and the control unit is arranged to control the distribution module to distribute electrical power to the battery if a total of the first amount of power and the second amount of power is less than an available amount of power provided by the first power source. This implementation allows locally generated energy to be stored, decreasing dependency on an external or public power grid by the local residencies.
5 In a further implementation, the distribution module is further arranged to provide electrical power to a public power grid and the control unit is arranged to control the distribution module to distribute electrical power to the public power grid if a total of the first amount of power and the second amount of power is less than an available amount of power provided by the first power source. This implementation allows for generating revenue by selling energy from the first source to third parties. Alternatively or additionally, this implementation may be used for absorbing electrical energy from a public power grid and/or other parties in case of an energy surplus on the grid. Such energy may be stored in a battery that may be comprised by the system.
In another implementation, the control unit 1s arranged to control the distribution module to distribute electrical power to the public power grid if a total of the first amount of power and the second amount of power is less than an available amount of power provided by the first power source and the battery is charged to a pre-determined level. This implementation improves independence from the public power grid or another external grid.
In again a further implementation, the distribution module is arranged to receive direct current electrical power from the first energy source and provide alternating current to the first residency and to the second residency; in this implementation, the distribution module further comprises a direct current to alternating current converter. This implementation is compatible with current practice in virtually all existing buildings. Yet, 1t may be envisaged to provide local direct current power grids, rather than alternating current grids. In such implementation, the direct current to alternating current may be omitted or replaced by a direct current to direct current converter, optionally for adjusting voltage.
A second aspect provides an apartment building comprising a photovoltaic panel as a first energy source, a first residency, a second residency and the system according to the first aspect or implementations thereof connected to the photovoltaic panel, the first residency and the second residency for distributing electrical power generated by the photovoltaic panel to the first residency and the second residency. It is noted that additionally or alternatively to the photovoltaic power source, energy may be generated using wind power, hydropower, other, or a combination thereof.
A third aspect provides, in an electronic power distribution system, a method of distributing electrical power received from a first power source to a first residency. The method comprises monitoring a first amount of electrical power received from first electrical power source and provided to the first residency and a second amount of power received from first electrical power source and provided to the second residency over a period of time in order to collect monitoring data; and distributing the electrical power from the first source over the first residency and the second residency by the distribution module based on the monitoring data.
It is noted that when distribution of power is discussed, distribution of energy over time is implicitly discussed, as energy equal power integrated over time. Such may be real power, reactive power, both or any other entity based thereon.
BRIEF DESCRIPTION OF THE DRAWINGS The various aspects and implementations thereof will now be discussed in further detail in conjunction with drawings. In the drawings: Figure 1: shows an electrical power system; Figure 2: shows a flowchart depicting a procedure; and
Figure 3: shows an alternative electrical power system.
DETAILED DESCRIPTION Figure 1 shows an electrical power system 100 comprising a solar panel 102 - a photovoltaic module - as a first electrical power source, a public power grid 104 as a second power source and a local power grid 110. The local power grid is connected to the solar panel 102 and connected to the public power grid 104 via a transformer 106. In one implementation, each individual dwelling is individually connected to the public power grid 104.
In another implementation, the total of all individual dwellings is connected collectively to the public power grid 104 with a single subscription. The local power grid 110 is preferably provided in an apartment building or another residential system with multiple dwellings, including, but not limited to, a group of houses or commercial spaces.
The local power grid 110 comprises a central power distribution module comprising a first central power distribution unit 112 as a distribution module, a first local power distribution unit 130 as a first residency control unit, a second local power distribution unit 140 as a second residency control unit, a battery module 118 and a central control module 120.
The central control module 120 comprises a central processing unit 122, a central storage unit 124, a central local communication unit 126 and an external communication unit 128. The central processing unit 122 is arranged, via the central local communication unit 126, to control the various elements of the local power grid 100, among others to execute the method according to the third aspect and implementations thereof. The central storage unit 124 is arranged to store data on power consumption by the apartments or other dwellings and to store computer executable code for programming the central storage unit 124.
The central local communication unit 126 is arranged to enable the central processing unit 122 to communicate with the various parts of the local power grid 110. The external communication unit 128 is arranged to communicate data to other systems, like the public power grid 104, outside the local power grid 110 over a wide area network 108.
The first central power distribution unit 112 is arranged to distribute electrical energy from the solar panel 102 over the first local power distribution unit 130 and the second local power distribution unit
140. The first central power distribution unit 112 is controlled by the central control module 120 to distribute a total amount of power over the first local power distribution unit 130 and the second local power distribution unit
140. The first central power distribution unit 112 may be arranged to sense how much energy provided by the solar panel 102 is provided to each dwelling and to provide such historic consumption data to the central control module 120.
The first central power distribution unit 112 comprises in this example an alternating current to direct current converter for converting direct current electrical power from the solar panel 102 to alternating current to be provided to the dwellings. In another example, direct current electrical power may be provided to the dwellings. In such example, the direct current to alternating current converter in the first central power distribution unit 112 may be omitted, bypassed when providing electrical power to the dwelling or replaced by a direct current to direct current converter.
The first central power distribution unit 112 is arranged to provide electrical power not consumed by any of the dwellings to the public power grid 104 and/or to the battery 118.
The first local power distribution unit 130 comprises an first power inlet for receiving electrical power from the first central power distribution unit 112, a second power inlet for receiving electrical power from the public power grid 104, a socket 138 as an example of a power outlet, a power detection unit 132 to determine electrical power demanded via the socket 138, a control unit 134 to demand a particular amount of power from the central power distribution unit 112 and a power sensing unit 136 arranged to sense an amount of power received from the central power distribution unit 112. In one particular example, the second power inlet may also be used to provide electrical power to the public power grid
104. The second local power distribution unit 140 comprises an first power inlet for receiving electrical power from the first central power distribution unit 112, a second power inlet for receiving electrical power from the public power grid 104, a socket 148 as an example of a power outlet, a power detection unit 142 to determine electrical power demanded via the socket 148, a control unit 144 to demand a particular amount of power from the central power distribution unit 112 and a power sensing unit 146 arranged to sense an amount of power received from the central power distribution unit 112. In one particular example, the second power inlet may also be used to provide electrical power to the public power grid
104. The functionality and operation of the second local power distribution unit 140 may be the same, equal to, equivalent to or identical to the functionality and operation of the first local power distribution unit 130. Therefore, only the functionality and operation of the first local power distribution unit 130, unless operation of both local power distribution units 18 discussed in conjunction with one another. The battery 118 is connected to the first central power distribution unit 112 for receiving electrical power for charging the battery 118 and for providing electrical power to the power distribution unit 112 in case of demand of electrical power from the battery 118.
Figure 2 shows a flowchart 200 depicting an example of the method according to the third aspect.
Below, brief summaries of the various parts of the flowchart 200 are provided. 202 start 204 receive data power supply 206 receive data power demand 208 demand higher than supply? 210 obtain past consumption data 212 supply power to dwelling with lowest consumption 214 all power supplied? 216 end 222 serve dwellings in accordance with demand 324 provide excess power to battery 326 battery charged? 328 provide excess power to public grid The procedure starts in a terminator 202 and continues to step 304 in which the power supply available from the solar panel 102 is determined.
Optionally, electrical energy available in the battery 108 may be taken into account as well, to further reduce dependency on power supplied by the public power grid 106. In step 206, data on demand for power in the dwellings is determined.
The demand may be determined in each separate dwelling by means of the power detection unit 132 and the power detection unit 142. The power sensing units of the local power distribution units send data on local power needs to the control unit 134 an the control unit 144, respectively.
The control units in the local power distribution units send the power need thus determined to the central power distribution unit or to the central control module 120. Alternatively or additionally, the power requirement is sensed by the first central power distribution unit 112 by determining electrical power demanded at its power outlet or power outlets to the dwellings. In step 208, the power demanded is compared to the power supply as both have been determined. The comparing, sensing and determining may be done on an instantaneous basis or at an interval basis, for example every second, every minute or other. It is preferred the interval is not too long, to take change of weather into account. In case the total demand for electrical power by all the dwellings 1s higher than the solar panel 102 can supply, the process branches to step 210. If the supply or potential supply of electrical power by the solar panel 102 is higher than the demand, the process branches to step 222 and step 224. In the latter case, a safety margin may be taken into account such that the process only branches to step 222 and step 224 if the supply exceeds the demand by a fixed or relative threshold. In step 210, historical use data of power consumptions by each the dwellings is obtained, for example retrieved from the central storage unit
124. The historical use data may be obtained over a fixed period of time - for example the past six months - or from a particular moment onward - for example the first of January of the applicable year. The historical use data may be adjusted for percentage of ownership or contribution in cost of ownership like maintenance and insurance per dwelling. In step 212, the power need of the dwelling with the lowest consumption retrieved is attended to. In step 214, it is determined whether the solar panel 102 supplies more electrical power than demanded by the dwelling with the lowest consumption thus far. It this is not the case, the process branches back to step 214 and another dwelling with the second lowest historical consumption is determined. This loop is repeated until all available power 1s assigned to the dwellings. Optionally, as discussed above, any energy in the battery module 118 and power that may be supplied by the battery module 118 may be taken into account here. Once the loop has ended, the procedure ends in a terminator 216. If the process has branched to step 222, all dwellings are served in accordance with their demands. In step 224, any batteries in the battery module 118 are provided with electrical power for charging the batteries. In step 226 is checked whether the batteries in the battery module 118 are charged. If this is not the case, the process branches back to step 224. If the batteries are charged, excess power is provided to the public power grid 104 in step 228. Once step 222 and step 228 are completed, the process ends in the terminator 216.
If the first local power distribution unit 130 and/or the second local power distribution unit 140 do not receive sufficient electrical power from the central power distribution unit 112, further electrical power is required from the public power grid. In the first local power distribution unit 130, the power sensing unit 132 senses an amount of power received from the first central power distribution unit 112. If the sensed amount is lower than a power amount determined by the power detection unit 132, the control unit 134 controls the first local power distribution unit 130 to demand additional power from the public power grid 104 to meet the total demand as determined by the power detection unit 132. The second local power distribution unit 140 works in the same or equivalent way.
Figure 3 shows an alternative electrical power system 100. The alternative electrical power system 100 comprises mostly elements equivalent to those of the electrical power system 100 shown by Figure 1, which function in the same way and will only be discussed to the extent their functionality is different or to the extent they provide additional functionality.
The local power grid 110 as shown by Figure 3 comprises two solar panels 102, each provided with a converter 116. It is noted that the solar panel 102 of Figure 1 may also be provided with a converter 116. The converters 116 connected the solar panels 102 to a central power bus 150. To the central power bus 150, the first central power distribution unit 112 and a second power distribution unit 114 are provided as the power distribution module.
In the implementation shows by Figure 3, one solar panel 102 - or group of solar panels 102 - and one power distribution unit are provided per dwelling.
In this implementation, one battery module 118 is provided; in another implementation, also one battery module 118 may be provided per dwelling.
By connecting the solar panels, the battery modules and the central power distribution units to the central power bus, each dwelling may have its own equipment, with responsibility for the particular equipment.
On the other hand, this implementation also provides the opportunity to share electrical power in case a solar panel 102 of a first dwelling provides more energy than the first dwelling requires; the excess power may be shared with a second dwelling.
Hence, this reduces dependency on the central power grid 104 to a minimum, thus potentially reducing cost of energy consumption for all dwellings.
As indicated above, the central control module 120 may be connected to the public power grid 104 via the wide area network 108. This allows the central control module 120 to obtain data on cost or price of electrical energy provided by the public power grid 104. The cost of electrical energy on the public power grid 104 may vary on a time basis and also data on future pricing may be available.
In case the cost of energy is low, the central control module 120 may control the local power grid 110 not to consume electrical energy stored in the battery module 118, but rather withdrawn electrical energy from the public power grid.
Likewise, in case the price of electrical energy is high, the central control module may control the local power grid not to charge the battery module 118 when excess power 1s available, but to give it back to the public power grid 104. Also further options for cost driven control may be envisaged.
In summary, a system provides distribution of electrical power generated by means of a private network over stakeholders in the private network. The energy may be distributed based on demand and past use; based on the past use, energy is distributed such that over time, energy is made available evenly over the stakeholders; such may depend on a particular share in the property of each stakeholder. The stakeholders may be apartments or other entities like small companies. Each stakeholder may have its own controller to determine local demand and send an energy request to a central distribution unit. The central distribution unit distributes the energy based on the distribution rule; if the stakeholder requires more energy, the controller may retrieve such electrical energy from another source, like a public power grid.
