Using historical data to predict future energy demand of power system plays a key role in solving the challenge of supply and demand balance of power system brought by renewable energy. In this paper, a multi-time scale power load forecasting method based on wavelet threshold denoising and Prophet is proposed. Firstly, the wavelet threshold denoising algorithm is used to de-noise the historical load data to reduce the influence of inherent noise caused by acquisition equipment and transmission equipment on the results. Then the Prophet algorithm is used to build a time series model of historical data, so as to predict the future power load. This method can predict the power load at different time scales according to different demands. Simulation results show that the proposed method has high prediction accuracy and stable prediction results for different time scales.

Heating elements are found to be prone to structural and functional problems such as adhesion and short circuit in engineering practice, which is due to illogical structural design and spatial arrangement of electric heating components. To overcome the foregoing difficulties, the structural parameters of the electric heating element are optimized using the finite element method, and the heat transfer properties of the device are studied. By varying the structure, diameter, and surface load of the heated wire, the heat transmission effects are compared. The experimental findings reveal that by reducing the surface temperature of the corrugated linear wire over the same surface area, the surface load of the heating system may be effectively lowered. The experimental results show that, for the same surface area, the corrugated linear band can effectively reduce the surface temperature; increasing the diameter of the linear heating wire can reduce the surface load and improve the service life of the heating wire, and the temperature decrease is not obvious when the linear heating wire diameter exceeds 8mm; increasing the heating wire power or surface load can increase the heating wire surface temperature;

In this paper, a fault voltage ride-through control strategy is developed for the grid-connected photovoltaic (PV) inverters. In this control strategy, a new phase-locked loop (PLL) is proposed to realize the grid voltage tracking under zero-voltage and unbalanced voltage faults. By detecting the voltage amplitude of the point of common coupling (PCC), the grid-connected PV inverter can switch its control strategy to realize the fault voltage ride-through, and inject a certain amount of reactive current to support the voltage recovery of the power grid. The CloudPSS is used to build an electromagnetic transient (EMT) simulation platform of the fault ride-through test system, and the simulation results prove the effectiveness of the proposed control strategy.

Flexible DC transmission system using modular multilevel converters (MMC) is facing the problem of DC fault clearance. The existing sub-module hybrid MMC uses full bridge sub-modules (FBSM) to achieve non-blocking fault ride-through (FRT), but the ratio of FBSM needs to reach 50% or more, the cost and operating loss are more than half higher than that of the half bridge MMC. This paper proposes a low ratio hybrid MMC suitable for DC fault clearance. When the ratio of FBSM is less than 50%, the DC output voltage is reduced to zero by reducing the value of the arm voltage proportionally to isolate the faulty line. This paper analyzes the fault isolation sequence and controller structure of the scheme. Finally, a simulation model is built in PSCAD/EMTDC to verify the effectiveness of the scheme.

C6F12O environmentally friendly insulating medium will decompose due to discharge and overheating failure. If the decomposition products are not adsorbed, it will pose a threat to the safety of equipment and personnel. In this paper, adsorption experiments were conducted to explore the adsorption effect of 13X molecular sieve and γ-Al2O3 on C6F12O superheated decomposition gas. The experimental results show that the pyrolysis products are C2F6, C3F8, C4F10, C3F6, C3F7H, C5F12, and C6F14. Both 13X molecular sieve and γ-Al2O3 have strong adsorption effect on C6F12O in the original gas. Through the adsorption experiment of standard gas, it can be seen that the adsorption effect of 13X molecular sieve on the common fluorocarbon decomposition products C3F7H, C3F6, and C3F8 gas is obvious, the adsorption rate is more than 70%, and the adsorption effect on C3F7H gas is 98.4%. The adsorption effect of γ-Al2O3 on C2F6, C3F7H, C3F6 and C3F8 was poor, and the highest adsorption rate was only 31.8%. Since 13X molecular sieve and γ-Al2O3 have strong adsorption effect on the main insulating gas C6F12O, both 13X molecular sieve and γ-Al2O3 are difficult to be used as adsorbents for C6F12O environmentally friendly insulating medium, but they can be used for the treatment of new environmentally friendly insulating medium tail gas treatment.

Under the two-carbon target, the large-scale access of renewable energy brings great challenges to the peak modulation, frequency modulation and fault recovery of the system. With the rapid development of information and communication technology, a large number of adjustable loads based on information and communication infrastructure, including communication base station backup energy storage (BSES) and internet data center (IDC), broaden the path of the power system to achieve the balance of power supply and demand, and can solve the prominent problems brought by renewable energy power generation. First, in order to make full use of BSESs and IDCs to consume the renewable energy, this paper studies the adjustable potential of BSESs and IDCs under different load levels, and constructs the BSESs and IDCs encapsulation model. Secondly, the virtual power plant (VPP) is considered as an effective way of distributed resource aggregation, so on the basis of ensuring the backup demand of BSESs and the normal operation of IDCs, this paper designs a multi-objective collaborative optimization control strategy of VPP to achieve the maximum consumption of renewable energy and the optimal operation economy of VPPs. Finally, the case study verifies the low carbon and operation economy under the contrast of single objective and multi-objective scenarios.

With the increasing proportion of renewable generation in the power system, the hydrogen storage is expected to play an important role in the future power system for its clean and efficient characteristics. As an important source of hydrogen storage, the electrochemical characteristics of hydrogen production from water electrolysis have a crucial impact on hydrogen production efficiency. In this paper, an XGBoost based prediction model is proposed for electrochemical characteristics of hydrogen production by water electrolysis under different operation conditions. Firstly, the over potential and impedance characteristics of electrolysis process were investigated through experiments under different temperature and concentration. Then, a performance prediction model of electrolysis hydrogen production is developed based on XGBoost. Test results show that the proposed prediction model is more practical compared with traditional machine learning methods for the analysis of electrochemical process of hydrogen production.

The data collected by distribution and consumption usually has different degrees of data quality problems, which severely restricts the application of various services in the power system. Therefore, this paper proposes a method for judging and automatically repairing the integrity of multi-source measurement data of power distribution and consumption based on the power grid business resources. The method includes a plurality of power grid service resource middle stations, and the power grid service resource middle stations include a human-computer interaction interface and an operation platform module, a data preprocessing module, an integrity judgment module, and an automatic repair module. The simulation results show that this method can realize the completeness judgment and automatic restoration of the multisource distribution electricity consumption measurement data with lower calculation cost, and improve the observability of the distribution network.
