Description

SYSTEM FOR WIRELESS POWER SHARING IN MICRO GRIDS
TECHNICAL FIELD
[0001] The present invention relates to systems for wireless power sharing in micro grids.
BACKGROUND
[0002] Small house holding solar panels and batteries are suitable for low power equipment typically running with 12 V battery configuration, powering typically LED light, small refrigerators, ceiling fan, cell phone charging, radio or other electronic equipment. For higher power demand equipment as TV, refrigerator, bigger ceiling fans, mills, machines or cooking are several solar panels and larger batteries required. It is not economically feasible for many private house holding with large solar panels to enable high power equipment. Small solar panel farms with power grid to individual homes can supply higher power supply, however these projects have high construction and maintenance cost.
[0003] CN 204669058 U discloses a wireless charging system for electric automobile based on storage from grid -connected electricity generation and storage power generation facility.
[0004] US 2017/0179723 discloses a clustered energy-storing micro-grid system includes a renewable energy device, a clustered energy-storing device, an electrical power conversion device and a local controller. Before coordinating and allocating power to a plurality of loads, the clustered energy-storing device stores and releases the power in a centralized manner. This, coupled with the control exercised by the local controller over the electrical power conversion device, controls the micro-grid system in its entirety so that the micro-grid system operates in cost-efficient optimal conditions, under a predetermined system operation strategy, and in a system operation mode.
[0005] For the areas with high poverty are solar farm/ wind turbine projects with power grid to expensive. It is therefore a need for in the market for a plug and play solution with low construction cost and no maintenance cost. It is also a market where it is beneficial to share the energy production capacity.
SHORT SUMMARY
[0006] A goal with the present invention is to overcome the problems of prior art, and to disclose a system for wireless power sharing in micro grids.
[0007] The invention solving the above mentioned problems is a system according to the independent claim.
[0008] An effect of the invention is that it increases the utilization of energy storage and generators as typical solar power will have peak production around midday and the battery connected together creates a buffer for collecting and distribute the energy.
[0009] When sharing energy, high power machines may be used and it may create opportunities for new workplaces, where work operation done earlier with human power is replaced machines.
[0010] Soldiers in the army can bring the individual power generation equipment and the storage unit, enabling them to be disconnected for a long time. When the soldiers are together they can dock the energy devices to the microgrid and create opportunities for e.g. cooking water
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Fig. 1 illustrates an energy storage device in an exemplary embodiment of the invention.
[0012] Fig. 2 illustrates an energy storage device in an exemplary embodiment of the invention.
[0013] Fig. 3 illustrates an energy storage device in an exemplary embodiment of the invention.
EMBODIMENTS OF THE INVENTION
[0014] In the following description, various examples and embodiments of the invention are set forth in order to provide the skilled person with a more thorough understanding of the invention. The specific details described in the context of the various embodiments and with reference to the attached drawings are not intended to be construed as limitations. Rather, the scope of the invention is defined in the appended claims.
[0015] A wireless power transfer consist of a transmitter (tx) and a receiver (rx) with inductive coils, either resonant og non-resonant. As illustrated in Fig. 1, an energy storage device (e.g. battery) or generator device (e.g. solar panel) may be in a first modus transmitting and receiving low power and low voltage. The device consist of a generator (e.g. solar panel) 3, the generator has an integrated or is connected with wire with a inductive wireless power transmitter 2. The wireless power is transmitted to an energy storage device (e.g. battery) 1. The energy storage device consists of both a wireless power receiver and transmitter. The power can be transmitted to the consumer 4. The consumer has a wireless power receiver and can use the power directly or it charges a battery. The receiver can also have USB power outlet for charging USB devices
[0016] In a second embodiment, as illustrated in Fig. 2 and Fig. 3, a plurality of portable devices delivers (Tx)/receives (Rx) energy in a second modus transmitting and receiving a high power and high voltage to a receiver connected to a micro grid. Using different coil winding turn ratios, each individual storage and production device can deliver energy individually at low voltage/power mode and it can connect to a central micro grid for high voltage/power equipment. All power from or to the micro grid transmitter/receiver docking 5 will be sent with AC or DC through a cabled connection to central sharing communication micro grid unit 6 All received and sent data will be logged at the central sharing communication micro grid unit 6. Fig. 3 also shows a central battery storage 8, a central power generation unit 7, and an AC to DC inverter 9 enabling power sharing the regular consumer power grid 10.
[0017] Individual house holdings can use the energy storage for light in the evening, the energy storage will be recharged with generator (e.g. solar panel) in the evening and morning. When the persons in the individual house holding go to work or school they may bring the portable energy storage and/or the generator. It ́s then connected to the micro grid central unit for recharging or energy transfer.
[0018] The central unit would typically be positioned at:
- a community hall,
- a school,
- a church,
- a working place or
- a cooking place where several house holding share the same cooking facilities.
[0019] When several production and storage units are connected, the available effect is high enough for typical 220/110V equipment.
[0020] Use of magnetic inductive power transfer, both resonant and non-resonant, as energy transfer methods enable an interface robust and reduced problems with human errors. The wireless power transfer has one or two way communication to regulate and ensure safe and reliable power transfer.
[0021] The wireless power transfer may also provide bi-directional data communication, enabling logging of used and delivered energy for each of the devices in an energy account. It enables opportunities to create incentives for creating energy. The energy account can be also be a marketplace for energy, resulting in possibility for people that are using less and produce more to sell surplus energy. The central unit will also be a user of energy and can be a buyer of the energy. In one example, block chain technology may be beneficial to use for the energy-sharing platform to keep track of the energy transfers. This is particularity useful if energy is delivered and received at several location.
[0022] In the exemplary embodiments, various features and details are shown in combination. The fact that several features are described with respect to a particular example should not be construed as implying that those features by necessity have to be included together in all embodiments of the invention. Conversely, features that are described with reference to different embodiments should not be construed as mutually exclusive. As those with skill in the art will readily understand, embodiments that incorporate any subset of features described herein and that are not expressly interdependent have been contemplated by the inventor and are part of the intended disclosure. However, explicit description of all such embodiments would not contribute to the understanding of the principles of the invention, and consequently some permutations of features have been omitted for the sake of simplicity or brevity.
