Abstract

Interconnection meter socket adapters are provided. An interconnection meter socket adapter comprises a housing enclosing a set of electrical connections. The interconnection meter socket adapter may be configured to be coupled to a standard distribution panel and a standard electrical meter, thereby establishing connections between a distribution panel and a user such that electrical power may be delivered to the user while an electrical meter measures the power consumption of the user. An interconnection meter socket adapter may be configured to be coupled to a DC-AC converter, which may be coupled to various energy sources. As such, the energy sources are coupled to an electrical power system. In addition, a connector such as a flexible cable or flexible conduit containing insulated wires can be provided for connecting various energy sources and/or sinks.

Claims

1. An interconnection meter socket adapter, comprising:

a housing enclosing a set of electrical connections, the housing configured to be coupled to a distribution panel and a meter;

the set of connections having an input portion and an output portion, wherein the set of connections couples the input portion to an input of the distribution panel and a utility side of the meter in parallel, and couples the output portion to an output of the distribution panel and a customer side of the meter in parallel;

a connector connected to an additional energy source and an energy sink; and

a measurement module measuring bidirectional power flow through the interconnection meter socket adapter, the measurement module monitoring customer power consumption and energy generation for the purpose of electrical power system planning, the measurement module further monitoring power consumption of the energy sink and energy generation of the additional energy source.

2. The interconnection meter socket adapter of claim 1, wherein the housing comprises a first flange and a second flange, the first flange covered by a ring.

3. The interconnection meter socket adapter of claim 1, wherein the housing is cylindrical.

4. The interconnection meter socket adapter of claim 1, further comprising a set of sockets configured to make contact with the meter, wherein the set of sockets are the output portion of the set of connections.

5. The interconnection meter socket adapter of claim 1, further comprising a set of jaw blades configured to make contact with the distribution panel.

6. The interconnection meter socket adapter of claim 1, wherein the housing further comprises a coupler configured to accept the connector.

7. The interconnection meter socket adapter of claim 6, further comprising a breaker coupled between the coupler and the meter.

8. The interconnection meter socket adapter of claim 6, wherein the connector includes a flexible cable or flexible conduit containing insulated wires configured to be coupled to the additional energy source and the energy sink.

9. The interconnection meter socket adapter of claim 1, further comprising a communication module coupled to the measurement module.

10. A method of connecting a renewable energy source and an energy sink and a residential customer to a power grid using a distribution panel and an interconnection meter socket adapter, comprising:

installing an interconnection meter socket adapter coupled to the distribution panel, the interconnection meter socket adapter coupled to at least the renewable energy source during a first period and at least the energy sink during a second period, and the interconnection meter socket adapter coupled to a meter;

measuring bidirectional power flow through the interconnection meter socket adapter, and monitoring customer power consumption and energy generation for the purpose of electrical power system planning; and

monitoring power consumption of the energy sink and energy generation of the renewable energy source;

wherein the interconnection meter socket adapter comprises a housing enclosing a set of electrical connections, the housing configured to be coupled to the distribution panel and the meter, the set of connections having an input portion and an output portion;

wherein the set of connections couples the input portion to an input of the distribution panel and the utility side of the meter in parallel, and couples the output portion to an output of the distribution panel and the residential customer side of the meter in parallel.

11. The method of claim 10, wherein the housing comprises a first flange and a second flange, both flanges covered by rings.

12. The method of claim 10, wherein the housing is cylindrical.

13. The method of claim 10, wherein the interconnection meter socket adapter further comprises a set of sockets configured to make contact with the meter.

14. The method of claim 10, wherein the interconnection meter socket adapter further comprises a set of jaw blades configured to make contact with the distribution panel.

15. The method of claim 10, wherein the housing further comprises a coupler configured to accept a connector.

16. The method of claim 15, wherein the interconnection meter socket adapter further comprises a breaker coupled between the coupler and the meter.

17. The method of claim 15, wherein the connector is a flexible cable or flexible conduit containing insulated wires configured to be coupled to the energy source and the energy sink.

18. The method of claim 10, wherein the interconnection meter socket adapter further comprises a measurement module measuring bidirectional power flow through the interconnection meter socket adapter.

19. The method of claim 18, wherein the interconnection meter socket adapter further comprises a communication module coupled to the measurement module.
