Description

Technical Field

[0001] The present invention relates to an energy system, and in particular to an energy internet based on energy interaction blocks and standardized communication protocols and a construction method thereof. Background Art

[0002] For a long time, power systems worldwide have been managed and operated in a centralized manner. A small number of large thermal power plants, through participation in electricity markets or dispatched by system operators, have dominated power system operations, with electricity generally flowing in a one-way cycle: generation, transmission, distribution, and consumption. Many other energy systems, such as thermal and natural gas, share similar characteristics.

[0003] Driven by the global goal of carbon neutrality, the energy system, the world's largest source of carbon emissions, is evolving from a centralized to a distributed structure. On the one hand, renewable energy sources, such as wind and solar power, are more suitable for distributed deployment than fossil fuels. On the other hand, to mitigate the randomness of renewable energy, the electric energy system is increasingly incorporating distributed public resources such as batteries, electric vehicles, and air conditioners.

[0004] However, the traditional centralized operation model of the electric energy system struggles to adapt to new distributed, multi-agent resources. These resources are numerous, individually small, and user behavior is random. System operators, who traditionally controlled only a few large power generation companies, have fundamentally struggled to effectively manage and control these resources. To address this issue, new technologies, such as virtual power plants and peer-to-peer trading, have developed rapidly in recent years. However, these technologies, focused on specific aspects, have been unable to bring about fundamental structural changes to the electric energy system.

[0005] In fact, many researchers have noted a prime example: the internet. At the end of the last century, during the so-called Web 1.0 era, the internet's structure resembled that of the electric power system: its operation was dominated by a small number of portals, users primarily engaged in passive reading, and information flowed generally in a one-way direction. However, a little over a decade later, the internet entered the Web 2.0 era, evolving into an open platform connecting billions of active users who can freely access relatively centralized portals and interact with each other. This is precisely the change we hope to see in the electric power system, and the concept of the Energy Internet has emerged.

[0006] However, in stark contrast to the rapid evolution of the internet, the concept of the Energy Internet has been proposed for 20 years, yet to this day, the electric power system still operates largely in a centralized model. The concept of the Energy Internet is not entirely clear, and there is a lack of clear implementation plans, making it difficult to truly form an "internet-like" energy system.

[0007] Specifically, existing energy internet technologies have the following shortcomings:

[0008] 1) The transmission medium is unclear: The transmission medium of the Internet is information, the transmission medium of the power system is electricity, and the academic community has not yet reached a consensus on the transmission medium of the energy Internet. It is also difficult to define what the users of the energy Internet are and what their attributes are.

[0009] 2) Lack of standardized interaction protocols: A key to the Internet’s ability to form a decentralized open system lies in its standardized communication protocols, which can complete standardized communication between users without the intervention of centralized institutions. This is exactly what the current energy Internet lacks.

[0010] 3) Unclear structure, and overly complex mainstream proposals: The academic community has not yet reached a clear conclusion on the structure of the Energy Internet. The current mainstream proposals include the physical layer, information layer, and value layer, which are quite different from the Internet and are overly complex.

[0011] It should be noted that the information disclosed in the above background technology section is only used to understand the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0041] Furthermore, the information part of the Energy Internet runs on the public Internet to allow users to exchange Energy Interaction Blocks (BEEs) without knowing the power system topology and parameters;

[0042] The information part of the power system dispatching operation runs independently on the power dedicated network and is physically isolated from the public Internet to ensure information security;

[0060] The present invention has the following beneficial effects:

[0061] The main technical advantage of the present invention is that it realizes the comprehensive standardization and structural optimization of the energy Internet, thereby breaking through the limitations of the centralized operation mode of the traditional power system and effectively adapting to the new distributed, multi-agent energy resource management needs. By introducing the energy interaction block (BEE) as a standardized medium for energy interaction, the present invention not only clarifies the measurement and transaction methods of energy in the energy Internet, but also promotes decentralized energy interaction and information communication between users by establishing a standardized communication protocol. In addition, the present invention simplifies and standardizes the structure of the energy Internet, making the system clearer, easier to understand and implement, similar to the openness and interactivity of the Internet, and realizing the "Internet-like" energy system.

[0062] The present invention also achieves effective decoupling of the energy internet and the dispatching and operation of the power system, so that the information part of the energy internet can run on the public internet, while the dispatching and operation of the power system is carried out independently on the power dedicated network, ensuring information security while allowing users to independently determine the way of energy interaction through energy internet applications without understanding the complex topology and parameters of the power system. In addition, in this energy internet, the existing dispatching and operation agencies can be transformed into energy internet service providers, which can predict or measure the net power injection of power system nodes, use standardized TCP and IP protocols to control user traffic, and dispatch centralized resources, thereby ensuring the safe and reliable operation of the power grid, optimizing network loss and voltage, and providing users with reliable and efficient energy internet services. These innovations have jointly promoted the efficiency of energy management and provided strong technical support for achieving the goal of carbon neutrality across society.

[0086] The features and advantages of specific embodiments of the present invention are further described below.

[0087] The embodiment of the present invention proposes an energy internet based on energy interaction blocks and standardized communication protocols and a construction method thereof, specifically providing: a design paradigm for the energy interaction block (BEE), and using it as a standardized transmission medium for the energy internet; a design paradigm for the configuration, functions and user portraits of the energy internet network card; the TCP / IP model structure of the energy internet and the main functions of each layer; the "Internet-like" overall structure of the energy internet; and a decoupled operation mode between the energy internet and power system scheduling.

[0088] Specifically, the energy internet based on energy interaction blocks and standardized communication protocols in the embodiments of the present invention has the following characteristics:

[0089] (1) The energy exchange block (BEE) proposed in this invention is used as the interaction medium. The energy exchange block is a complex composed of standardized characteristic information vectors and the actual energy interaction during system operation. Therefore, in order to realize the flow of the energy exchange block, a link between the Internet and the corresponding energy system must be established between the flow source and the target. Some design examples of the energy exchange block information vector are shown in Table 1 below:

[0090] Table 1

[0091]

[0092] (2) The Energy Internet Network Card proposed in this invention is used as the basic unit. Each Energy Internet Card has a unique Energy Internet MAC address, which defines the basic unit in the Energy Internet. It is a module composed of software and hardware that parses the energy interaction blocks sent or received and uses them to update the user portrait of each basic unit, including the unit's BEE record, green certificate inventory record, and carbon emission rights inventory record.

[0093] (3) The energy internet TCP / IP model proposed in the present invention or its extension is used as a standardized communication protocol between basic units. The energy internet TCP / IP model consists of a link layer, a network layer, a transport layer and an application layer. The link layer establishes a connection between the internet and the energy system between energy internet units and assigns a unique MAC address to each energy internet network card. The network layer uses the internet IP protocol as a reference to assign an energy internet IP address to each energy internet node and implements long-term (monthly or longer) flow control, i.e., energy block transmission rate limits. The transport layer uses the internet TCP protocol as a reference to establish reliable links between energy internet units and implements real-time flow control based on system security. The application layer is responsible for various future energy internet applications, and energy internet users determine how they transmit BEEs through these applications. With the support of the above standardized interaction media, user portraits and communication protocols, energy internet users can achieve BEE interaction and user portrait updates between users without the intervention of system operators.

[0094] (4) The energy internet designed by the present invention has the following structure similar to the internet. Each basic unit of the internet can find its corresponding part in the energy internet, such as Figure 1 shown.

[0095] Energy LAN: A local area network composed of local resources, represented by a virtual power plant. The virtual power plant provides energy internet router services, serving as the structure of the energy LAN and wide area network. An example design of an energy internet router is as follows: Figure 2 shown.

[0096] The energy internet router has one or more of the following configurations: a virtual power plant optimal dispatch (VPP optimal dispatch) function to optimize the allocation and dispatch of power resources; solid state transformers (Solid State Transformers) or other virtual power plant flow controllers (Other VPP flow controllers) to manage and regulate energy flow; a service provider (SO / ISP)-oriented function to support the specific needs of service providers; a distributed energy resource (DER)-oriented function to support the integration and management of distributed energy resources; an energy internet card (Energy Internet Card) with a wide area network MAC address (WAN MAC) for communication and identification in the energy wide area network (WAN); an energy wide area network (Energy WAN) port for connecting to the wide area network of the energy internet; an energy local area network (Energy LAN) port for connecting to the energy local area network (LAN); a connection interface with distributed energy resources (DERs) for communicating and exchanging energy with DERs; and a connection to the main grid to ensure interconnection with a wider energy system.

[0097] Energy Intranet: An energy local area network with independent operation capabilities, represented by microgrids

[0098] Energy WAN: A wide-area energy internet that connects multiple energy local area networks across a large area, represented by interconnected power grids.

[0099] Energy Internet Service Provider (Energy ISP): represented by power grid dispatching and operation organizations, which implement energy Internet traffic control and dispatch centralized resources based on sensitive information such as network topology and parameters, provide stable and reliable energy Internet services to energy Internet users, and charge energy Internet service fees based on the above dispatching and control costs.

[0100] Energy Web Server: A service provided by Energy Web users to ensure the stable and reliable operation of the Energy Web.

[0101] Energy Block Library (BEEbase Server): Similar to a database, it relies on energy storage devices such as energy storage and information storage media to provide BEE access services for energy Internet users

[0102] Energy Internet Domain Name System (Energy Internet DNS): A domain name resolution system that facilitates public user access and participation.

[0103] (5) In the energy internet proposed in the present invention, the operation of the energy internet and the dispatching operation of the power system can be decoupled. The information part of the energy internet runs on the public internet. Users do not need to know sensitive information such as the power system topology and parameters. The exchange method of the energy interaction block is determined in the energy internet application. The information part of the power system dispatching operation still runs on the current power private network, which is physically isolated from the public internet to ensure information security. The existing dispatching operation organization will be transformed into an energy internet service provider. It does not need to know or review the specific decisions of users in the energy internet. Instead, it predicts or measures the net power injection of power system nodes, implements user traffic control through the energy internet TCP protocol and IP protocol, and dispatches centralized resources, including centralized wind and solar power stations and hydropower and pumped storage power stations, to ensure the safe and reliable operation of the power grid, and optimize network losses, voltage, etc., to provide users with reliable energy internet services.

[0104] The present invention also has the following alternative embodiments:

[0105] (1) The energy interaction block design is only an example and may be adjusted as the technology evolves.

[0106] (2) The Energy Internet TCP / IP model can be expanded to other communication protocol models, such as the OSI model. The specific communication protocol can also be replaced with other types of protocols, such as replacing the TCP protocol with the UDP protocol.

[0107] (3) With the further evolution of technology, the structure of the energy Internet and the positioning and functions of its components may also be adjusted.
