With carbon peaking and carbon neutrality, the low-carbon energy big data management system uses advanced digital technology to effectively control the carbon emissions and new energy consumption of key enterprises with high energy consumption in real time, accurately quantify the carbon emissions and green energy use of enterprises, and help enterprises to reduce costs, improve efficiency, rationally plan and reduce carbon emissions. In this paper, the author uses the analytic hierarchy process, from three aspects of economy, environment and society, to give weight to indicators, and the topsis model to evaluate the comprehensive benefits between the installation of photovoltaic in 2017 to the use of low-carbon energy big data management system in 2021. The results show that in the application scenario of "green energy code", the low carbon energy big data management system can provide auxiliary decision for increasing the use of green energy, reducing energy consumption, decreasing emission reduction, and controlling planning, which aims to promote the development of green and low carbon economy. On this basis, the low carbon energy big data management system can help the low carbon energy big data management system expand its market and create multiple values by expanding user coverage, deepening application scenarios and innovating business models.
Based on the current energy situation of the world, the safety operation and maintenance needs of users are more and more important. Considering the hysteresis and passivity defects existing in the traditional energy safety operation and maintenance system, this paper analyzes an intelligent energy safety operation and maintenance system by combining modern Internet communication technologies. Firstly, a five-dimensional spatio-temporal database is established with historical and real-time data through the ‘cloud-edge-to-end’ data collection system. Then, data optimization is worked based on intelligent algorithms such as PCA, PSO and etc., which can achieve the automatic scene recognition and diagnosis. The intelligent energy safety operation and maintenance system proposed in this paper can quickly and accurately diagnose energy usage scenarios based on real-time operation data, intelligent identification of faults and optimal operating conditions, which can achieve the goal of ensuring the safe operation of equipment.
The safe operation and maintenance of lithium batteries not only needs to monitor the working status of lithium batteries timely and accurately, but also needs to evaluate its health status and automatically switch the backup battery when safety hazards are found. However, research on the safe operation and maintenance of lithium batteries is still lacking. In light of this, this paper constructs a safe operation and maintenance mechanism by monitoring the voltage and surface temperature of the lithium battery. In addition, a novel online health assessment model based on GRU-CNN is proposed to find out the potential safety hazards of lithium batteries timely. The working voltage, current and ambient temperature are used as the input features of the model to predict the degradation of lithium batteries in advance. In addition, a security operation and maintenance controller is designed to quickly switch the backup battery pack when a lithium battery pack appears to have performance degradation or security risks. The system realizes the real-time monitoring of the safe operation of lithium batteries and the rapid assessment of health status, providing technical guarantees for the reliable, stable, and safe operation of the lithium battery system. The experimental comparison verified that the proposed assessment model of the status of health (SOH for short) has less prediction error.
Energy safety operation and maintenance system is a fast and accurate fault diagnosis process. With the trend of digital development in today's world and the gradual improvement of enterprise's energy safety structure, it is urgent to design a new energy safety operation and maintenance system to ensure the safety of enterprise energy equipment. In this paper, AI and artificial hard rules are combined to design a energy safety operation and maintenance system to replace the old energy safety operation and maintenance system. The historical data of energy equipment is used to build a cloud database, and the data is acquired by sensors in real time for updating and iteration. The scene diagnosis model is built according to the original data and applied to energy safety operation and maintenance system. When the sensor obtains data in real time and input it into the model calculation, the data can be optimized, the risk can be predicted, and the energy scenario diagnosis can be completed quickly and accurately.
