IDENTIFICATION POWER CHIP FOR GRID-INTEGRATED ENERGY DEVICESBACKGROUNDTechnical Field
[0001] Embodiments herein generally relate to a semiconductor, and more particularly to an identification power chip for grid-integrated energy devices.Description of the Related Art
[0002] The integration of distributed energy resources (DERs), smart meters, and various consumer and industrial appliances into modern smart grids has become a critical challenge for energy management systems. The proliferation of these devices, each with unique operational characteristics, has introduced significant complexity in managing, monitoring, and optimizing energy flows across electric grids. As a result, ensuring secure, reliable, and standardized communication between energy devices and grid management systems such as Supervisory Control and Data Acquisition (SC AD A), Advanced Distribution Management Systems (ADMS), Distributed Energy Resource Management Systems (DERMS), and Energy Management Systems (EMS) has become a priority for electric utilities and grid operators.
[0003] Traditionally, energy devices have required manual configuration or external identification systems to register their characteristics with grid management systems. This approach has resulted in inefficiencies, particularly in the deployment of distributed energy resources (DERs) like solar inverters and energy storage systems, where the need for rapid and autonomous device identification is paramount. Additionally, the variety of communication protocols employed by different grid systems, such as IEC 61850, IEEE 2030.5, DNP3, and Modbus, has created interoperability challenges. Energy devices are often constrained to a single protocol or requireextensive customization to communicate with diverse grid systems.
[0004] Further complicating the integration process is the critical requirement for robust cybersecurity. As energy devices increasingly interact with grid systems, ensuring the authenticity and integrity of data transmissions is essential. Unsecured communication between devices and grid management systems exposes critical infrastructure to malicious attacks, such as data tampering or unauthorized access, potentially leading to significant disruptions.
[0005] To address these challenges, there is a need for a chip that can overcome drawbacks and disadvantages of existing solutions, which are limited in scope, focusing on specific grid architectures, or lack the multi-protocol flexibility and robust cybersecurity measures required for future smart grid applications.SUMMARY

The various embodiments throughout the disclosure will be explained in more detail with reference to FIGs.1-4.
[0036] FIG. 1 illustrates an exemplary block diagram of the identification power chip for grid- integrated energy devices, in accordance with an embodiment of the present disclosure. An energydevice 10 may include distributed energy resources (DERs). DERs may be a small-scale, localized energy device near consumers that generates, stores, or manages electricity. DERs may include rooftop solar panels, small wind turbines, battery storage, fuel cells, small hydropower units, and electric vehicles.

The power grid / grid entity 20 may include a supervisory control and data acquisition (SCADA) systems, advanced distribution management systems (ADMS), distributed energy resource management systems (DERMS), and energy management systems (EMS).
[0038] In one or more embodiments, the energy device 10 may include an identification power chip 100 embedded therein. The identification power chip 100 may include a chip, or a semiconductor system on a chip (SoC). The identification power chip 100 may include a processing element 104. In one or more embodiments, the processing element 104 may include or be coupled to at least one of a data acquisition module 102, a communication module 106, a cybersecurity module 108, a processing module 110, and a self-diagnostic module 112.
[0039] In one or more embodiments, the identification power chip 100 may include data acquisition module 102. The data acquisition module 102 may be configured to receive a plurality of electrical parameters associated with the energy device 10. The plurality of electrical parameters may include but not limited to a device type, device descriptors, voltage, amperage, power quality metrics, power generation metrics, and / or energy consumption patterns, for use in autonomous identification by grid entity 20. The data acquisition module 102 may include one or more sensors that may be configured to measure electrical parameters associated with the energy device 10. Formeasuring electrical parameters like voltage and amperage, the data acquisition module 102 may employ specialized transducers such as Current Transformers (CTs) and Voltage Transformers (VTs), which safely measure electrical flow without direct contact. To determine power quality metrics, the data acquisition module 102 may use the raw data from the sensors and process the data with a dedicated processing element 104, which may use a fast Fourier transform (FFT) to analyse waveform distortions like harmonics. For power generation and energy consumption patterns, the data acquisition module 102 may use advanced filtering algorithms to integrate realtime voltage and current measurements over time, effectively acting as an advanced energy meter. For obtaining device’s type and descriptors, the data acquisition module 102 may rely on a combination of a pre-programmed unique identifier (UID) and a sophisticated analysis of the device’s unique electrical signature, which is a specific pattern of electrical usage and characteristics. The plurality of sensors may also sense the internal environment of the grid entity 20 and one or more parameters associated with the energy device 10. The plurality of sensors may include integrated circuits and on-chip sensors for intelligent self-identification service. The sensors may be communicatively connected with the identification power chip 100. The sensors may be configured for transmitting data or values associated with the energy device 10 and the grid entity 20.
[0040] In one or more embodiments, the processing element 104, either through or at the data acquisition module 102, may be configured to process electrical characteristics using advanced filtering algorithms such as Fourier Transform (FFT) for power quality analysis and predictive analytics to detect anomalies in power usage or potential device failures. The data acquisition module 102 may utilize a combination of filtering algorithms, for e.g., digital filters to reduce noise, and real-time data analytics to process the captured electrical characteristics. The filteringalgorithm may include a Fourier Transform (FFT) to analyze harmonic content and power quality and / or a Moving Average Filter to analyse smooth voltage and current readings over time.
[0041] In some embodiments, the identification power chip 100 may include processing module 110, which may be used by the processing element 104 to execute different operations. The processing element 104 may receive a plurality of electrical parameters associated with the energy device 10 from the data acquisition module 102. The processing element 104 may obtain a digital certificate based on a unique identifier (UID) of the energy device 10 and determine a communication protocol compatible with the grid entity 20. The processing element 104 may transmit the plurality of electrical parameters, the UID, and the obtained digital certificate to the grid entity 20, according to the determined communication protocol. The processing element 104 may receive a challenge message from the grid entity 20 based on the transmission and transmit a signed message to the grid entity 20 using a private key associated with the digital certificate, where the signed message is verifiable using a public key in the digital certificate.
[0042] In one or more embodiments, the processing element 104 may perform self-diagnostics and calibration to maintain accurate device identification and power characteristics over time, such as using the self-diagnostic module 112. The processing element 104 may perform calibration through an embedded calibration routine within the identification power chip 100, which can be either a one-time or periodic process. During the initial setup, the processing element 104 may be configured to perform a one-time calibration, which typically establishes a plurality of baseline parameters for energy device 10 identification and power characteristics. For periodic recalibration, the identification power chip 100 may compare the formatted electrical parameters obtained in real time against predefined thresholds to set a baseline for each of the electrical parameters (such as voltage and current). This periodic recalibration may be triggered by usage patterns or set intervals,ensuring the energy device 10 adjusts to evolving environmental conditions, including changes in temperature and load variations, over time.
[0043] In some embodiments, the identification power chip 100 may include communication module 106. The communication module 106 may be included in or coupled to or operated by the processing element 104. The communication module 106 may support and dynamically switch between multiple standardized communication protocols, including but not limited to IEC 61850, IEEE 2030.5, DNP3, and Modbus, for interoperability with various grid management systems. The communication module 106 may include a protocol detection module 106A. Upon initial connection to or during ongoing communication with the grid entity 20, the protocol detection module (not shown) may be configured to automatically identify the protocol requirements of the grid entity 20, by scanning for supported communication protocols, including but not limited to IEC 61850, IEEE 2030.5, DNP3, and Modbus. Upon identification of the communication protocol, the communication module 106 may perform a communication protocol handshake process to establish a secure and compatible communication link. For example, a distributed energy resource (DER) like a solar inverter may be connected to a local utility that uses IEC 61850 for substation automation. When the communication module 106 initiates communication with the utility’s SCAD A system, the protocol detection module detects the IEC 61850 protocol via initial handshaking and selects this protocol for data exchange. Subsequent transmissions from the device 10 to the grid entity may be executed according to the selected protocol.
[0044] In one or more embodiments, the communication module 106 and / or the processing element 104 may be configured to switch the communication protocol in response to communicative coupling of the energy device to a different grid entity. In the foregoing example, if the same solar inverter is connected to another system using IEEE 2030.5 (e.g., commonly usedfor smart grid applications), the communication module 106 may switch to this protocol to ensure seamless communication. The communication module 106 may include an adaptable communication interface (not shown) that can switch between different protocols based on the grid entity 20 that it is interacting with.
[0045] In some embodiments, the communication module 106 may transmit the electrical parameters, along with a unique identifier (UID) and a digital certificate, for identification of the energy device 10 by the grid entity 20.
[0046] In some embodiments, the identification power chip 100 / processing element 104 may include cybersecurity module 108. The cybersecurity module 108 may authenticate the energy device 10 within the power grid 20 through a cryptographic challenge-response mechanism based on its UID and digital certificate issued by a trusted certificate authority. The cybersecurity module 108 embedded within the identification power chip 100 may provide advanced security features to safeguard the integrity of the transmitted data. The cybersecurity module 108 may also implement multi-layered security features such as data encryption using cryptographic algorithms like Advance Encryption Standards (AES), secure authentication via Public Key Infrastructure (PKI), and secure boot to ensure that data is protected from unauthorized access and tampering. During communication, the unique identifier and digital certificate may be used to authenticate the energy device 10 with the grid entity 20, by verifying the cryptographic signature, thereby ensuring that only authorized energy devices 10 can transmit data. For example, initially, the grid entity 20 initiates an authentication process by sending a challenge message to the identification power chip 100. In response, the identification power chip 100 responds by signing a (challenge) message with the private key of the energy device 10 (i.e., the private key associated with the digital certificate). The grid entity 20 verifies the response from the identification power chip 100, using the publickey embedded in the digital certificate associated with the unique identifier (UID) of the energy device 10.
[0047] In some embodiments, the identification power chip 100 may integrate an analog -to-digital converter (ADC) for precise measurement of electrical characteristics, and support a range of energy devices 10 including distributed energy resources (DERs) (e.g., solar inverters, battery storage systems), smart meters, and consumer appliances, enabling widespread compatibility with both legacy and modern smart grid infrastructures.
[0048] In some embodiments, the identification power chip 100 may include the processing module 110. Among other functions, the processing module 110 may be configured to analyze real-time data from the data acquisition module 102. The real-time data analytics may implement a predictive model. The predictive model may include a machine learning mode or statistical model to detect anomalies in power usage or potential device failures, enhancing device reliability and performance through proactive monitoring. The processing module 110 may format the data in accordance with standardized communication protocols, for communication in standardized packet structures based on the selected communication protocol, including GOOSE messages for IEC 61850 or register-based formats for Modbus, thereby ensuring seamless interoperability across protocols while preserving core energy device 10 metrics. Each communication protocol uses a specific data structure, but the core data such as a device type, voltage, amperage, and power quality metrics that are embedded within the data packet remain consistent. For instance, in IEC 61850, data is organized into generic object-oriented substation event (GOOSE) messages to support event-driven communication, whereas in Modbus, the data is formatted as registers for periodic polling. Regardless of the communication protocol used, these core electrical characteristics / data associated with the energy device 10 are packaged into a standardized format aligned with theselected communication protocol, thereby ensuring effective interoperability across systems.
[0049] In some embodiments, the identification power chip 100 may include self-diagnostic module 112. The self-diagnostic module 112 performs automated tests on the sensors, the communication module 106, and the cybersecurity module 108 encryption systems during startup to ensure operational integrity, including sensor functionality, communication readiness, and security compliance. The self-diagnostic module 112 may (self-)test the sensors to ensure that voltage, amperage, and other sensors are functional. The self-diagnostic module 112 may verify that the communication module 106 (e.g., supporting IEC 61850, Modbus, etc.) is operational during a communication check. The self-diagnostic module 112 may verify the integrity of the encryption and authentication systems (e.g., verifying that the secure boot process has not been compromised), during security checks. The self-diagnostic module 112 may verify that the internal memory and storage are intact, during memory and data integrity checks. The self-diagnostic module 112 may monitor internal voltage regulators to ensure the semiconductor identification power chip 100 is receiving the correct power levels, during power supply checks.
[0050] In an embodiment, the identification power chip 100 may include self-diagnostic module 112, to perform self-diagnostic routine 300 each time the identification power chip 100 is initialized, or during first set-up, as shown in FIG. 3. The self-diagnostic routine 300 may include a self-test of the sensors, a communication check, a security check to verify the integrity of the cryptographic mechanism, a memory test to ensure that the memory is not corrupted, and a power supply check to ensure the identification power chip 100 is receiving the correct power levels. In other embodiments, the self-test routine and / or calibration routine may be executed periodically based on the received electrical parameters, usage patterns, set intervals, and environmental changes, but not limited thereto.
[0051] In some embodiments, the identification power chip 100 may be a standardized, secure, and interoperable chip that can autonomously identify energy devices, dynamically adapt to various communication protocols, and ensure the security of transmitted data. The identification power chip 100 may enable energy devices 10 to autonomously identify themselves to various grid entities 20 including grid management systems, such as Supervisory Control and Data Acquisition (SC AD A), Advanced Distribution Management Systems (ADMS), Distributed Energy Resource Management Systems (DERMS), and Energy Management Systems (EMS). This identification process may securely transmit important power and energy characteristics, including voltage, amperage, and power quality, via multiple standardized communication protocols. The identification power chip 100 also includes advanced encryption and authentication mechanisms, ensuring secure, real-time communication with grid entities 20 including electric utilities, grid operators, and third-party energy aggregators.
[0052] In some embodiments, an architecture of the identification power chip 100 may integrate the data acquisition module 102, the processing element 104, the communication module 106, and the cybersecurity module 108 and may support dynamic switching between multiple communication protocols such as IEC 61850, IEEE 2030.5, DNP3, and Modbus, thereby ensuring compatibility with both legacy and modern grid systems. Security features include encryption based on the Advanced Encryption Standard (AES), secure authentication using Public Key Infrastructure (PKI), and a unique digital identifier for each chip. These measures ensure secure, authenticated communication between energy devices and grid management systems, protecting against unauthorized access and data tampering.
[0053] In some embodiments, the identification power chip 100 may significantly improve integration of the energy device 10 by enabling seamless communication with grid entities 20,enhancing grid security, and ensuring compatibility with diverse grid infrastructures. The identification power chip 100 may simplify deployment and management of the energy device 10, making it indispensable for modern and future smart grids.
[0054] In some embodiments, the identification power chip 100 may autonomously identify the energy devices 10 to the grid entities 20, using dynamic communication protocols and facilitate real-time, secure communication through advanced encryption and authentication mechanisms. The self-diagnostics, recalibration, and multi-layered cybersecurity features of the identification power chip 100 may be a distinguishing feature relative to the prior solutions, and ensure compatibility across both legacy and modern grid systems while maintaining high data integrity and reliability. The identification power chip 100 may provide a scalable solution, embedding seamlessly within any grid-connected device to enable streamlined integration with grid management systems.
[0055] In some embodiments, the identification power chip 100 may integrate autonomous energy device 10 identification, real-time data processing, multi-protocol communication, and advanced cybersecurity features, and provide substantial benefits to the grid entity 20, in terms of device integration, management, and security. Through autonomous identification capabilities, the identification power chip 100 may enable energy devices 10 to automatically transmit essential parameters such as voltage, amperage, and power quality to the grid entity 20 without the need for manual setup.
[0056] In some embodiments, the identification power chip 100 may be engineered for low-power consumption to minimize the impact on the energy usage of the energy device 10. The power consumption of the identification power chip 100 varies based on processing and communication demands, typically ranging from a few milliwatts in standby mode to a couple of watts when active.This efficient power profile ensures that the identification power chip 100 does not significantly influence the host device’s overall energy usage. In energy-sensitive applications, such as distributed energy resources (DERs) or smart meters, the chip’s power-saving features including sleep modes, and low-power data transmission, enable the host energy device 10 to operate efficiently without compromising communication capabilities.

The computer system 400 also includes a memory 406.
[0064] Control logic (software) and data may be stored in the memory 406, which may take a form of random-access memory (RAM). In the disclosure, a single semiconductor platform may refer to a sole unitary semiconductor-based integrated circuit or chip. It should be noted that the term “single identification power chip 100” may also refer to multi-chip modules with increasedconnectivity that simulates on-chip modules with increased connectivity which simulate on-chip operation, and make substantial improvements over utilizing a conventional central processing unit (CPU) and bus implementation. Various modules of the identification power chip 100 may also be situated separately or in various combinations of semiconductor platforms per the desires of the user.
[0065] The computer system 400 may also include a secondary storage 410. The secondary storage 410 may include, for example, a hard disk drive and a removable storage drive, representing a floppy disk drive, a magnetic tape drive, a compact disk drive, digital versatile disk (DVD) drive, recording device, universal serial bus (USB) flash memory. The removable storage drives may perform at least one of reading from and writing to a removable storage unit in a well-known manner.
[0066] Computer programs, or computer control logic algorithms, may be stored in at least one of the memory 406 and the secondary storage 410. Such computer programs, when executed, may enable the computer system 400 to perform various functions as described in the foregoing. The memory 406, the secondary storage 410, and any other storage are possible examples of computer- readable media.
[0067] In an implementation, the architectures and functionalities depicted in the various previous figures may be implemented in the context of the processor 404, a graphics processor coupled to a communication interface 412, an integrated circuit (not shown) that is capable of at least a portion of the capabilities of both the processor 404 and a graphics processor, a chipset (namely, a group of integrated circuits designed to work and sold as a unit for performing related functions, and so forth).
[0068] Furthermore, the architectures and functionalities depicted in the various previousdescribed figures may be implemented in a context of a general computer system, a circuit board system, a game console system dedicated for entertainment purposes, an application-specific system. For example, the computer system 400 may take the form of a desktop computer, a laptop computer, a server, a workstation, a game console, an embedded system.
[0069] Furthermore, the computer system 400 may take the form of various other devices including, but not limited to a personal digital assistant (PDA), a mobile phone, a smart phone, a television, and so forth. Additionally, although not shown, the computer system 400 may be coupled to a network (for example, a telecommunications network, a local area network (LAN), a wireless network, a wide area network (WAN) such as the Internet, a peer-to-peer network, a cable network, or the like) for communication purposes through an I / O interface 408.
[0070] In some exemplary embodiments, when a distributed energy resource (DER) such as a solar inverter with the identification power chip 100 is turned on and begins operating, the following sequence of events will occur to ensure a secure and seamless connection to the power grid 20. When the solar inverter, equipped with the identification power chip 100, is turned on, a precise sequence of events ensures that the solar inverter can connect to the power grid 20 safely and efficiently. The process begins with the self-diagnostic module 112 of the identification power chip 100 performing a comprehensive self-check. The self-diagnostic routine verifies that all internal components including the sensors and communication module 106 to the cybersecurity module 108 are working correctly, ensuring the identification power chip 100 is ready for operation. The data acquisition module 102 acquires data from the sensors and provides to the processing module 110 to initiate a calibration routine. The processing module 110 analyses the inverter’s real-time electrical data such as voltage and amperage and compares the values against a set of predefined benchmarks. By comparing, the processing module 110 establishes a reliable baseline for theinverter's performance. The baseline is essential for solar device to accurately identify the power grid 20 and the associated characteristics. The communication module 106 takes over to connect to the power grid 20 and initiate a connection with a local utility’s SCADA system, the identification power chip 100 installed within the solar inverter may initiate a handshake process. The handshaking process allows the system 100 to detect that the utility system utilizes the IEC 61850 protocol for substation automation. In response, the identification power chip 100 automatically selects and switches to the detected / determined protocol i.e. IEC 61850 protocol in the case, for all data exchange. If the same inverter were to connect to a different grid system that uses IEEE 2030.5 for smart grid applications, the identification power chip 100 may again detect the protocol and seamlessly may switch to IEEE 2030.5 protocol, ensuring continuous and compatible communication.
[0071] Once the communication protocol is determined, the cybersecurity module 108 authenticates the solar inverter through a cryptographic challenge-response mechanism using the UID and a digital certificate of the solar inverter. In the cryptographic challenge-response mechanism, the power grid 20 sends a challenge message to the solar inverter, to which the identification power chip 100 installed / embedded within the solar inverter responds with a signed message using a private key. The power grid 20 verifies the signature using the public key from the digital certificate associated with the UID. Upon verification, a secure link is established between the solar inverter and power grid 20. The processing module 110 formats the data of the solar inverter into the correct packet structure, and the communication module 106 transmits this formatted information, over the communication protocol IEC 61850 and thus allows the solar inverter to be fully and securely identified by the power grid 20.
[0072] Therefore, the proposed identification power chip and method enable an energy device toautonomously and securely communicate the operational characteristics to various grid management systems, such as a solar inverter reporting its energy generation. The identification power chip 100 overcomes the limitations of traditional systems by providing a single, standardized solution that can automatically adapt to different communication protocols and protect data from cyber threats. In essence, the present disclosure provides a universal digital passport for energy devices, making the integration into modern smart grids more efficient, secure, and interoperable.
