This invention relates to the field of industrial automation and control network technology, and discloses a real-time synchronization method system for LonWorks networks based on digital twin variables. Applied to LonWorks fieldbus networks, it is implemented based on a heterogeneous node system consisting of a general-purpose processing module, a LonTalk protocol processing module, and a high-speed serial communication bus. The general-purpose processing module carries a manager, the LonTalk protocol processing module maintains standard LonWorks network variables and has a built-in LonTalk protocol stack, and the high-speed serial communication bus transmits DTVP data frames. This invention achieves a significant leap in node computing power, freeing nodes from the limitations of dedicated communication chips and allowing them to directly utilize the high performance of industry-leading general-purpose microcontrollers to easily handle complex control algorithms, real-time data filtering, lightweight artificial intelligence inference, and other complex tasks.

The application discloses a natural gas network system model construction method and a parameter identification method. The method comprises the following steps: constructing a partial differential dynamic equation physical model of a natural gas pipeline, discretizing the model into a difference equation model, setting a topological constraint condition of the natural gas network, setting a natural gas network variable, and determining a natural gas network system model; outputting learned parameters of the model through the natural gas network system model; setting a model parameter identification loss function; updating an initial state of the natural gas network system and the learned parameters of the model in combination with the loss function; and determining parameter values of the natural gas network system model when a termination condition of the updating is met. The application does not depend on accurate model parameters of a natural gas network system, but can realize parameter identification of the system with physical interpretability only according to measurement results of the network. The established natural gas system is a linear dynamic model, has high precision, and can be widely applied to simulation calculation and scheduling decision.

The invention presents method and system for prioritizing Channel State Information (CSI) reports in 5G / 6G New Radio (NR) networks through enhanced integration with Rel-19 uplink control information (UCI) packing rules. The disclosed techniques dynamically assign priority levels to multiple CSI reports containing CSI-RS Resource Indicators (CRIs), thereby improving efficiency and reliability of data transmission under limited uplink resources. In one aspect, priority rules are based on the number of reported CRIs (M), the number of non- reported CRIs (M R ), or a combination of both, ensuring that critical information is transmitted first. The invention further conditions priority assignment on network variables such as serving cell index and CSI configuration parameters, while also enabling prioritization according to beam quality measures including SINR, RSRP, RI, and CQI. These methods provide robust omission handling, maintain backward compatibility with legacy CSI rules, and support deployment with large antenna arrays across frequency ranges FR1, FR2, FR3, and beyond.

The method does not significantly increase the complexity of the system, can adaptively adjust the post-fault reference value according to the fault severity, takes into account the current limiting requirement and the correct action demand of the current differential protection, at the same time prevents the occurrence of repeated low voltage ride through phenomenon, and effectively improves the reliability of the differential protection under the power electronic weak feedback characteristic.

Analysis of context can comprise analyzing, based on an artificial intelligence model, the contexts of the network function as compared to known and / or stored contexts.

A method which is improved relative to the prior art for controlling electrical network variables in a feed network, in which the correlation between at least one feed variable measured at an input of the feed network and at least one network variable measured at an output of the feed network is described in a model-like manner using a model of the feed network. In the event of an incorrect description of the correlation, an adaptation of the model of the feed network is carried out, a feed variable target value for the at least one feed variable is determined from a predefined network variable target value for the at least one network variable using the model of the feed network, and the at least one feed variable is set to the determined feed variable target value by of a current converter.
