Description

ENERGY MANAGEMENT SYSTEM
FIELD OF THE INVENTION
0001. The present invention relates generally to systems for the automation of monitoring and controlling electrical appliances to reduce/contol energy consumption and increase energy efficiency for households, industries, offices, institutions and off-grid solutions.
BACKGROUND OF THE INVENTION
0002 A smart meter is an energy meter that is connected with the cloud directly trough an IOT: protocols e.g. Sigfox, 4g or Narrowband-IOT. This system has a sub-system to provide usage, instant or monthly, to the utility facility for billing and Supply planning purposes. These meters are designed for standalone in an urban area. 0003 A gateway
A gateway system is the data collector and the link towards the cloud. The data from this point can be distributed again.
Ef 0004 side control equipment * A side controlled equipment is external control product which can be controlled with Modbus / RS- 485, Ethernet or Wlan. An example of this product is a motor driver which can be set trough RS- 485. 0005 Synchronized switching(load balancing)
Synclivonized switching is used to synchronize all temperature operated equipment e.g. an oven, deep fryer, etc. These machines normally tum on to the given temperature and then switches off when the desired temperature is reached, when the temperature internally drops to a certain threshold, The synchronized switching turns off all the machines at different times knowing what power consumption the specific device uses. The synchronized switching gives a time slot for the machines to operate in, thus creating a balanced load with synchronizing the machines. 0006 Mesh network
A mesh network {or simply meshnet) is a local network topology in which the infrastructure nodes (i.e, bridges, switches, and other infrastructure devices) connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one : 35 another to efficiently route data from/to clients. This lack of dependency on one node allows for : every node to participate in the relay of information. Mesh networks dynamically self-organize and self-configure, which can reduce installation overhead. The ability to self-configure enables dynamic distribution of workloads, particularly in the event a few nodes should fail. This in turn contributes to fault-tolerance and reduced maintenance costs. 0007 An energy management system can be a Smart meter, a power measuring module, a gateway, a Smart home system, {off)grid distribution panels, or a campus wide energy management system through network control and monitoring. 0008. A Smart IOT system is usually a mobile network control system with cloud control and 2.4 GHZ WiFi communications. All intelligence is controlled in the cloud and from far away. These systems mainly address home automation and there is usually no proactive energy saving control scenes in side the network for fast switching of controlling sensors.
These system often heavily rely on WiFi and mobile networks and do not work in temporary events and off-grid situations. 1
0009. However, each of the above energy management devices has its weakness. For example regular smart meters only report on static installations. In dynamic installations its working is not guaranteed due to the fact the wireless infrastructure is not available or not adequate for the data transfer. Side controlled equipment thus must be directly controlled inside the system to optimize energy control and consumption.
SUMMARY OF THE INVENTION
0010. The present invention provides a system, which measures the voltage, current, power factor 60 and power consumption of each appliance plugged in the system, And is able to sample the values over time and send an average value over an 868 MHZ frequency band to a cloud application. The appliance contains a large buffer capacitance, in case of grid failure the system continues to measure. Inside the system there is side control equipment that is being controlled from the collected data conserving energy and controlling the grid with synchronized switching making the 65 system stable and independent from cloud and surounding infrastructure.
In one embodiment, the Software application can be configured to monitor individual nodes in a ¢ network and give alerts of power failure in the following cases: missing neutral, zero voltage per * phase, over-current alert precaution, Load balancing alert and optimization in energy designs. The 70 hardware can be configured to average the measurements in a buffer over a AT and send iin a to a gateway to transfer the data to the cloud. The power circuit of the hardware contains a power buffer that enables the system to send data even when the grid power is gone, The system is able to control synchronize the energy consumption from inside the network, whilst being able to be controlled from afar. 75
In another embodiment, when a plurality of the system are implemented in multiple premises, the gateway and peripheral appliances can even be located in any physical locations around the world.
For example, two different power systems are positioned in the field, one of the systems has a temperature meter as side equipment and the other has an energy meter node in its network and a 80 Synchronized switching module as side equipment. The first gateway read the data from the temperature sensor and detects the value is lower than the threshold. Its sends a signal to the other gateway that the heater must be activated, The gateway is set up with Synchronized switching load balancing. Its creates a time slot for the system to be activated in and waits for the measured load to go down. The system starts to sync the heater on the time slot, balancing the load. ‚85 * 0011 Features are designed to provide minimal effort and less intervention required by the users to maintain effective and efficient energy saving. =~ 0012 Smart meter 90 The Smart meter has the following properties: Continuous sampling of Power, Voltage, Current, power factor, and Harmonics. It has a power buffer for power outage and has programmable alerts to control side control equipment. In figure 2 is shown the flow of the smartmeter. 0013 Gateway 95 The Gateway of this invention has peripherals to control side control equipment directly, and has connection to the cloud for data/ control transfer. 0014 The Cloud
The Cloud in this invention has the properties to preset the threshold or set a dynamic threshold for 100 all the side control equipment and the energy meters to directly control all the data. 2
0015 The Mesh is a data communication level for the all the nodes in the field so the data always arrives to the designated location and providing a strong and reliable system. 105 0016 Side control equipment in this invention can be read as a normal system from the gateway and be controlled in it it. 0017 Synchronized switching{load balancing) in this invention is the control system for non intellectual machines, so the power load can be balanced. 110 (018 In one embodiment the network is configured by setting smart meters in the field and using the mesh to send the data to a gateway. This gateway can control added side equipment and control load on the network directly and can read for example an external mid certified meter. All the data then is send to the cloud. If there is a grid power loss the system still sends the data to the gateway 115 notifying power failure. This is then send to the cloud. The system is able to apply synchronized switching to optimize the power usage. > Brief description of invention 120 Fig.1 shows a connectivity overview of the gateway management system.
