DETAILED DESCRIPTION

[0091] FIG. 1 schematically shows a monitoring installation 100 comprised in a monitoring system 110 according to the invention for monitoring and/or controlling at least one electrical parameter 111 in an electrical supply system 10, wherein the electrical supply system 10 comprises at least one decentralised energy supply system 12, here in the form of a photovoltaic system 19, and at least one electrochemical battery storage 11. In addition, further electrically operated and/or operable components 20 of an electrical supply system 10 are connected to the monitoring installation 100.

[0092] Said components 20 may comprise the external or public energy supply grid 14, an at least partially electrically chargeable or fully electrically operated vehicle 22 or a charging station 23 for charging such a vehicle, a heat pump 21 for generating and/or providing heat, as well as other electrically operated consumers 15 such as smart home devices or electrically operated and/or operable devices.

[0093] The measuring installation 13 of the monitoring installation 100 is configured to capture, read out and, if necessary, optimise electrical parameters 111 of the above-mentioned components 20 of the electrical supply system 10 via at least one port 16 in real time and without/with the intervention of a user. The electrical supply system 10 is configured to store unused electrical energy in the electrochemical battery storage 11 and to release it to the above-mentioned components 20 on demand.

[0094] A monitoring installation 100 for monitoring and/or controlling at least one electrical parameter 111 in an electrical supply system 10 is provided according to the invention, which, in addition to the monitoring installation 100, also comprises an internet server 30 and a user terminal 40. The internet server 30 is connected via an internet interface 31 in a monitoring system 110 to the monitoring installation 100 for transmission of the data of the electrical parameters 111 measured by the measuring installation 13 to a computer program, in particular an app 51, which can be executed on a user terminal 40 and is configured to provide a user with visualisation of the measured electrical parameters 111 of the components 20 as well as at least one possibility for controlling them.

[0095] FIG. 2 schematically shows two non-limiting forms of energy supply of a monitoring system 110 for monitoring and/or controlling at least one electrical parameter 111 in an electrical supply system 10. The upper schematic shows an island operation 120, in which electrical energy for at least one consumer 15 is obtained from the electrical supply system 10, in particular from at least one decentralised energy supply system 12, in this case in the form of a photovoltaic system 19, or from at least one intermediate storage, in particular at least one electrochemical battery storage 11. Thereby, at least one grid and system protection, NA protection 17, ensures a decoupling of the electrical supply system 10, comprising decentralised energy supply system 12 and electrochemical battery storage 11, from an external energy supply grid 14, in order to prevent a grid feed-in and/or overloading of said external energy supply grid 14. Further below, a conventional grid operation 130 from an external energy supply grid 14 for the consumer(s) 15 is shown, with the addition that in this exemplary embodiment the decentralised energy supply system 12 is decoupled from the user by at least one contactor 18, so as to prevent grid feed-in of electrical energy into the external energy supply grid 14. However, this does not preclude energy generators in an electrical supply system 10, for example a photovoltaic system 19, from generating electrical energy and feeding it into the electrochemical battery storage 11 for later use.

[0096] Together, these two embodiments of a current supply form a so-called peninsula operation 140, in which it is ensured that the at least one NA protection 17 and the at least one contactor 18 are never closed at the same time, in order to accordingly prevent a grid feed-in of electrical energy from decentralised electricity generators into the public electricity grid and thus ensure a zero feed-in, so that an overload of the external energy supply grid 14 can be prevented. In this way, power consumption from the external energy supply grid 14 can be minimised and self-supply can be maximised with the help of decentralised supply systems, e.g. photovoltaic systems 19.

[0097] FIG. 3 shows an exemplary embodiment of a graphical display 60 implemented by initiating a computer program 50, in particular an app 51, wherein the graphical display 60 provides a user with the at least one electrical parameter 111 of at least one component 20 in an electrical supply system 10 measured by the measuring installation 13 of the monitoring installation 100 by means of an internet protocol and graphically displays said electrical parameters 111 and the associated energy flow 112 by means of a user interface 52. This provides the user with a clear, graphical display 60 of the energy flow 112 of the components 20 connected in the electrical supply system 10 in a simple manner. The components 20 connected to the measuring installation 13 of the monitoring installation 100 in the electrical supply system 10 are arranged in a circle in this display 60. Thereby, the arrows indicate the respective energy flow 112, either from the electrical supply system 10 to the components 20 connected to the measuring installation 13, as shown here, an electrically operated vehicle 22, at least one consumer 15, a heat pump 21 and also an external energy supply grid 14, according to their orientation. Temporarily non-existing energy flow 113 is indicated with a minus sign in this non-limiting exemplary embodiment. It should be noted, although not shown here, that the orientation of the arrows for at least the electrochemical battery storages 11 as well as the external energy supply grid 14 are indicated as both incoming and outgoing arrows respectively corresponding to the energy flow 112. This can mean, for example, that electrical energy can be fed-in to and/or withdrawn from the external energy supply grid 14 and/or at least one electrochemical battery storage 11 as required and an update of the graphical display 60 takes place in accordance with the energy flow control.

[0098] In addition to the energy flows 112 measured by the measuring installation 13, respective electrical parameters 111 from the components 20 connected to the measuring installation 13 and electrochemical battery storages 11 and photovoltaic systems 19 comprised in the electrical supply system 10 are displayed, such as for example the electrical power supplied, fed or discharged, as well as parameters derived therefrom, such as a charge level 114 of an electrochemical battery storage 11 or an electrically powered vehicle 22, as well as the heat 115 generated by a heat pump 21, in order to realise an easily understandable and clear graphical display 60 of the most important electrical parameters 111 of the monitoring installation 100 for a user.

[0099] The graphical display 60 described herein is additionally configured to graphically display the energy flow 112 measured by the measuring installation 13 in real time and, respectively, its electrical parameters, essentially also in real time, and to update the graphical display 60 accordingly. In addition, the respective components 20, such as the electrochemical battery storage 11 and the photovoltaic system 19, which are represented by icons in the graphical display 60, can be clicked on individually to display a more detailed representation of the electrical parameters 111.

[0100] FIG. 4 shows an exemplary embodiment of a graphical display 60, implemented by initiating a computer program 50, in particular an app 51, wherein the graphical display 60 displays, by means of an internet protocol, the at least one electrical parameter 111, measured by the measuring installation 13 of the monitoring installation 100, of at least one component 20, in particular of all components 20 integrated in the monitoring system, as described in FIGS. 1-3, in an electrical supply system 10 to a user and displays by means of a user interface 52 to which portion the measured electrical parameters from an external energy supply grid 145 and/or an electrical supply system 105 comprising at least one electrochemical battery storage 11 and at least one photovoltaic system 19 contribute to the operation of the components 20 described in FIGS. 1-3. In other words, this graphical display 60 indicates to a user the portion of self-sufficient energy supply that is provided.

[0101] FIG. 5 shows an exemplary embodiment of a graphical display 60 realized by initiating a computer program 50, in particular an app 51, wherein the graphical display 60 by means of an internet protocol provides to a user the at least one electrical parameter 111, measured by the measuring installation 13 of the monitoring installation 100, of at least one component 20, in particular of all components 20 integrated in the monitoring system, as described in FIGS. 1-3, in an electrical supply system 10 and indicates by means of a user interface 52 to what portion the stored and/or decentrally generated energy 157, and/or energy provided by the electrical supply system 10 is required for self-consumption 155, or can be fed-in 156 to the external energy supply grid 14.

[0102] FIG. 6 shows an exemplary embodiment of a graphical display 60 realized by initiating a computer program 50, in particular an app 51, wherein the graphical display 60 provides, by means of an internet protocol, the at least one electrical parameter 111, measured by the measuring installation 13 of the monitoring installation 100, of at least one component 20, as described in FIGS. 1-3, in an electrical supply system 10 to a user and graphically displays the energy balance 158 by means of a user interface 52. Thereby, a stacked column diagram shows the energy required for self-consumption 155 or generated by an electrical supply system 10, wherein the column of self-consumption 155 is subdivided into energy from a portion of feed-in 156 from an external energy supply grid 14 as well as a portion of generated energy for self-consumption 161, and the column of generated energy 159 is subdivided into a portion of generated energy for self-consumption 161 as well as a portion of generated energy for feed-in 160 into an external energy supply grid 14. The columns thereby represent absolute energy values, for example measured in kWh. In addition, the generated energy for self-consumption 161 and generated energy 159 are also displayed in respective pie charts, as relative values in percent. Furthermore, a selection option 170 is realized for a user, with which the user can select a time period for which the energy balance is to be displayed and/or exported.
