Abstract

A microgrid according to an exemplary aspect of the present disclosure includes, among other things, a plurality of intelligent electronic devices configured to communicate directly with one another in a first language. Each of the intelligent electronic devices includes a controller and a gateway. The gateway is configured to convert incoming messages from the first language to a second language native to the controller. The first language is different than the second language. A method is also disclosed.

Claims (30)

1. A microgrid for communicating between intelligent electronic devices, the microgrid comprising:

a plurality of intelligent electronic devices configured to communicate directly with one another in a first language, wherein each of the intelligent electronic devices includes a controller and a gateway, the gateway being configured to convert incoming messages from the first language to a second language native to the controller, wherein the first language is different than the second language,

wherein each of the intelligent electronic devices include a first language stack, the first language stack configured to send and receive messages in the first language,

wherein each first language stack includes an incoming first language application configured to parse incoming bits into a message in the first language, and place the parsed messages into an incoming first language queue,

wherein each gateway receives the parsed messages from the incoming first language queue and associates each parsed message with a message in the second language, and wherein the gateway places the messages in the second language in a second language queue,

wherein each controller is configured to determine an intelligent electronic device function corresponding to the messages in the second language queue,

wherein each intelligent electronic device includes an outgoing second language application configured to parse bits into a message from the respective intelligent electronic device in the second language, and to update a variable corresponding to the parsed message from the respective intelligent electronic device and

wherein the first language stack is configured to generate an outgoing message in the first language based on the update to the variable, and to place the outgoing message in an outgoing first language queue.

2. The microgrid as recited in claim 1 , wherein each gateway is configured to recognize a predefined message in the first language and to identify a corresponding message in the second language.

3. The microgrid as recited in claim 1 , wherein each intelligent electronic device includes a wireless transceiver configured to transmit and receive messages to a wireless transceiver of another intelligent electronic device in the microgrid.

4. The microgrid as recited in claim 1 , wherein the messages in the outgoing first language queue are transmitted to at least one of the other intelligent electronic devices in the microgrid.

5. The microgrid as recited in claim 1 , wherein the plurality of intelligent electronic devices includes at least two of an energy management system, a grid switch, a regenerative elevator system, a generator, a lighting system, an HVAC system, a computer, and a battery management system.

6. The microgrid as recited in claim 5 , wherein at least some of the second languages native to the controllers of each of the intelligent electronic devices are different from one another.

7. A method of communicating between intelligent electronic devices within a microgrid, comprising:

communicating a message directly from a first intelligent electronic device to a second intelligent electronic device in a first language;

converting the message from the first language to a second language native to a controller of the second intelligent electronic device, the first language being different from the second language;

receiving the message as a plurality of bits at the second intelligent electronic device;

parsing the bits into a message in the first language;

placing the parsed message into an incoming first language queue;

recognizing the message from the incoming first language queue as a predefined message in the first language and identifying a message in the second language corresponding to the predefined message;

placing the identified message in the second language in a second language queue;

executing a function of the second intelligent electronic device in response to the message from the second language queue; and

generating bits corresponding to a message indicating the function has been performed;

parsing the generated bits into a message in a second language;

updating a variable in response to the message in the second language;

generating an outgoing message in the first language based on the update to the variable; and

placing the outgoing message in an outgoing first language queue.

8. The method as recited in claim 7 comprising:

transmitting the outgoing messages in the outgoing first language queue to another intelligent electronic device.

9. The method as recited in claim 7 , wherein the first intelligent electronic device is one of an energy management system, a grid switch, a regenerative elevator system, a generator, and a battery management system, and wherein the second intelligent electronic device is another of an energy management system, a grid switch, a regenerative elevator, a generator, a lighting system, an HVAC system, a lighting system, and a battery management system.
