“…In the same way as the IP is part of the Open System Interconnection (OSI) model, the packet dispatching can represent only part of a more complex view, as described in [10]. Following this approach, the Energy Packet would perform the abstraction of the devices that physically transmit the data.…”

“…In [13] and [12], viceversa, practical solutions for the implementation of energy routers are proposed. As already introduced in [10], the IP approach used in communication networks can inspire a complete restructuring of the electrical energy system. Following the definition at the beginning of the section, some key characteristics emerge:…”

“…As stated in Section 2, this represents one of the main analogies with the computer network technologies and the key aspect that has to be investigated to enhance this new vision. As described in [2] [13] and in [10], the main element of the information attached to the energy packet is the address, which supports the dispatch of the energy packet to the specific destination. Moreover, some other information could be added in order to exchange additional data between the sender and the receiver such as length of the packet and other possible useful information for the receiver -increasing, however, the complexity of the message itself.…”

“…The intention of the present simulation example is to describe the application of the PSMD technique for the energy packet generation and dispatch. The simulated system is a low voltage (LV) DC circuit composed by a main bus where all the loads and generators are connected [7] [10]. All the tests have been performed in Matlab/SIMULINK environment with SimPowerSystem toolbox.…”

The current process of transformation affecting the energy system is calling for completely new approaches. This paper investigates the possibility of introducing energy packets as a fundamentally new abstraction concept that is following the transformation of communication networks in the 1970s from synchronous circuit switching to asynchronous store-and-forward routing. Focus is placed on the exploitation of power electronic devices in creating information embedded into the power flow. Considerations on some criticalities and future developments that are needed to further proceed on the development of this new vision are discussed. A simple test in Matlab/SIMULINK is provided in support for the packet dispatching described in the paper.

“…However, it must be said that specialized Fourier techniques (such as zoom or sliding), paired with an appropriately coded digital signal processor can be quite efficient. Lastly, in [7], frequencies from 16-26 Hz are injected onto the grid from a voltage source converter in the form of "energy packets" (in regard to energy being a major control parameter), and each frequency represents a 0 bit or 1 bit for a specific converter. This is probably the most similar to LFCC, however, the utilization of the injected frequencies is quite limited, and the use of binary representation could mean a considerable amount of time would have to pass before the communication is decoded.…”

This paper provides a simple low-level unidirectional global communication method for DC microgrids, and requires no hardware modifications to the microgrid and interfacing power electronic converters. The underlying premise to this communication method is injecting low-frequency low-voltage sinusoidal components into the DC microgrid power lines. This method deviates from the common bit-level communication scheme by relating parameters and commands with certain frequency components. Communication structures are included as a basis for communication protocols, and a detection method is proposed for detecting the injected frequencies. The injection method, communication structure, and detection method are implemented on a live-scale DC microgrid.
