Definitions

  • the present invention relates to a system for the control of electric energy, in particular a system for the smart control of the electric energy of a domestic/residential type of user point.
  • Peripheral nodes such as homes for example, usually use units for the production of renewable energy to:
  • peripheral nodes Depending on the type of use of the renewable energy produced, two types of peripheral nodes mainly exist:“grid-connected” or“stand-alone”.
  • “grid-connected” means a system wherein the unit for the production of renewable energy is connected in parallel to the public network for the distribution of electric energy.
  • a“grid-connected” system comprises:
  • a plurality of photovoltaic panels (or other devices for the production of renewable energy) adapted to transform solar energy into electric energy; a system of storage by means of accumulators which conserves the energy not consumed for use when the photovoltaic panels do not produce energy (e.g. at night); and an inverter equipped with a DC- AC converter block to stabilize the energy produced or stored and to transform it at the voltage and frequency of the loads (in the case of transfer of panels/accumulators towards the loads) or at the voltage and frequency imposed by the electric energy distribution network operator (in the case of transfer of panels/accumulators to the network).
  • the electric energy distribution network will be expected to feed the excess demand into the home, together with that produced by the panels. In such case, the user will pay the excess energy to the distribution network operator.
  • the excess energy can be stored in the batteries or be fed into the public distribution network through the“exchange on the spot” system and calculated through special bi-directional meters. In the latter case, the distribution network operator may pay or compensate for the sale of energy produced by the photovoltaic panels.
  • the“stand-alone” peripheral nodes unlike the“grid connected” type, are isolated from the electric energy distribution network and have accumulators that store the energy not consumed to use it when the photovoltaic panels do not produce energy (e.g., at night).
  • the“grid connected” systems can be equipped with dedicated connections to connect electric cars to the public distribution network.
  • These systems commonly called“vehicle to grid” or“V2G” do in fact permit the addition of a further accumulator (the car battery), the energy of which can flow bi directionally to and from the public distribution network, to make it possible not only to charge the battery of the electric vehicle but, if necessary, for dispatching reasons, to return the electric energy previously stored in the battery of the electric vehicle to the network.
  • One object of the present invention is therefore to provide a system for the control of electric energy with functional characteristics such as to meet the above requirements and at the same time to overcome the problems mentioned with reference to the prior art.
  • FIG. 1 is a connection diagram showing a first embodiment of the system according to the present invention
  • FIG. 2 is a connection diagram showing a second embodiment of the system according to the present invention.
  • FIG. 3 is a connection diagram showing a third embodiment of the system according to the present invention.
  • FIG. 4 is a connection diagram showing a fourth embodiment of the system according to the present invention.
  • reference numeral 1 globally indicates an electric energy distribution system in accordance with the present invention.
  • the system 1 comprises:
  • the accumulator 8 can comprise at least one direct current battery, e.g. of the lithium-ion or nickel-cadmium type;
  • connection section 13 for the electric connection to the electric energy distribution network 3.
  • the connection section 13 e.g. consists of an electric connection node, i.e. in a simple point of connection to the electric energy distribution network 3, or in a more complex electronic device, such as an electric panel, an electric circuit comprising multiple nodes, or the like;
  • the charging point 14 for the connection to an electric vehicle 9 provided with a rechargeable battery.
  • the charging point 14 in turn comprises:
  • the AC/DC converter 5 can be of the unidirectional type (in which case the electric current drawn from the electric energy distribution network 3 can be used to charge the battery of the electric vehicle 9) or of the bidirectional type (in which case it is possible to draw the electric current from the electric energy distribution network 3 to charge the battery of the electric vehicle 9 and, if necessary, draw electric current from the battery of the electric vehicle 9 and feed it into the electric energy distribution network 3); and
  • the DC/DC converter 7 which is adapted to place the electric vehicle 9 in electric communication with the accumulator 8.
  • the fact that the DC/DC converter 7 is of the bidirectional type makes it possible to draw electric current from the accumulator 8 to charge the battery of the electric vehicle 9 and, if necessary, draw electric current from the battery of the electric vehicle 9 to charge the accumulator 8.
  • One of the objects of the DC/DC converter 7 is to convert the DC voltage of the accumulator 8 into a DC voltage suitable for the battery of the electric vehicle 9 and vice versa.
  • the system 1 of the present invention can operate in different conditions according to the environmental conditions, according to the user's need and/or according to public energy redistribution needs.
  • system 1 can operate under at least one of the following conditions, which can also be combined with each other:

  • the AC/DC converter 5 comprises:
  • connection section 13 a first alternating section 5a connected to the connection section 13; and a second direct section 5b connectable to the electric vehicle 9.
  • the DC/DC converter 7 comprises:
  • the electric vehicle 9 can be freely connected to and disconnected from the charging point 14 to allow the separation of the electric vehicle 9 from the system 1 and its use as a means of transport.
  • Figure 1 shows a first embodiment of the system 1, wherein the second direct section 5b of the AC/DC converter 5 and the second direct section 7b of the DC/DC converter 7 are connected to a common connecting node 15 connectable to the electric vehicle 9 along a connecting stretch 16.
  • the AC/DC converter 5 is of the unidirectional type and can only be crossed by the electric energy coming from the electric energy distribution network 3, through the connection section 13, and cannot flow in the opposite direction.
  • FIG 2 shows a second embodiment of the system 1 which differs from the first one by the fact that the charging point 14 comprises at least one bidirectional auxiliary DC/DC converter 24, positioned along the connecting stretch 16.
  • the auxiliary DC/DC converter 24 e.g. comprises:
  • a further DC/DC converter which permits sizing the components, i.e., the AC/DC converter 5, the DC/DC converter 7 and the auxiliary DC/DC converter 24, in a particularly convenient way according to the real needs of the system 1, e.g., in terms of electric power to be transferred through the charging point 14 and of transfer efficiency.
  • the AC/DC converter 5 is also of the unidirectional type and can only be crossed by the electric energy coming from the electric energy distribution network 3, through the connection section 13, and cannot flow in the opposite direction.
  • Figure 3 shows, on the other hand, a third embodiment of the system 1 which differs from the first one by the fact that the second direct section 5b of the AC/DC converter 5 and the second direct section 7b of the DC/DC converter 7 coincide with each other.
  • the AC/DC converter 5 and the DC/DC converter 7 consist of a three-port hybrid inverter and the AC/DC converter 5 is of the bidirectional type, thus allowing crossing the electric energy either from or towards the electric energy distribution network 3.
  • Figure 4 shows a fourth embodiment of the system 1, which shows a more articulated implementation of the embodiment of Figure 1, to which, however, reference should be made as regards the detailed description of the AC/DC converter 5 and of the DC/DC converter 7, with the variant, already previously provided for, that the AC/DC converter 5 of the embodiment in Figure 4 be of a bidirectional type.
  • the system 1 shown in Figure 4 is associated with a user point (e.g. a dwelling house) comprising one or more loads 12.
  • connection section 13 in fact, is associable with at least one load 12 of the user point and is adapted to send electric energy to the load itself.
  • the system 1 comprises a distribution module 11 connected to the connection section 13 and provided with one or more electric connectors 4 to which the loads 12 are associable to power them.
  • the distribution module 11 also comprises a meter to count the flow of electric energy circulating in the user point.
  • the system 1 also comprises at least one unit for the production of renewable energy 6 and at least one inverter device 2 which is adapted to place in electric communication:
  • unit for the production of renewable energy shall be meant to indicate units for the production of energy by wind, geothermal, hydroelectric, marine, and/or solar systems.

  • the inverter device 2 comprises:
  • a second alternating section 2b connected to the connection section 13; and a third direct section 2c connected to the accumulator 8 and to the DC/DC converter 7.
  • the system 1 of the present invention comprises a switching node 10 connected to the accumulator 8, to the inverter device 2 and to the DC/DC converter 7 to direct, if necessary, the energy flows in a bidirectional way between the accumulator 8 and the DC/DC converter 7, between the DC/DC converter 7 and the inverter device 2 device or between the accumulator 8 and the inverter device 2.
  • the presence of the loads 12 and of the unit for the production of renewable energy 6 enable the system 1 of the present invention to operate in even more diverse operating conditions depending on needs.
  • the system 1 of Figure 4 can also operate under the following conditions:
  • connection section 13 the user, in accordance with the present invention, is connected to the public electric energy distribution network 3, which typically supplies alternating current energy.
  • connection section 13 the user point in accordance with the present invention is also connected to the photovoltaic panels 6 which provide for renewable energy typically in direct current.
  • the renewable energy produced by the photovoltaic panels 6 can therefore power the loads 12 through the inverter device 2 meant to transform it from direct to alternating current (condition of drawing renewable energy and condition of powering the loads 12).
