SF6 gas has good insulation performance, but it has been gradually restricted to use because its strong greenhouse effect. In recent years, the search for alternative gases of SF6 has become a research hotspot of scholars. The ionization and attachment coefficients in SF6/CO2/N2 and CF3I/CO2/N2 gas mixtures with different proportions were calculated by the Boltzmann equation, the relationship between critical breakdown field strength (E/N)lim and mixing ratio was also obtained. The AC breakdown characteristics of SF6/CO2/N2 and CF3I/CO2/N2 gas mixtures under 0.1 MPa and uniform electric field were studied experimentally. The results showed that the critical breakdown field strength and AC breakdown voltage of SF6/CO2/N2 and CF3I/CO2/N2 gas mixtures both decreased with the increase of CO2 content. The critical breakdown strength and AC breakdown voltage of SF6/CO2/N2 gas mixtures was always higher than that of CF3I/CO2/N2 gas mixtures at the same ratio, but the gap between them decreased with the increase of CO2 content.

The construction scheme of floating photovoltaic power stations is greatly affected by hydrological, meteorological, geological and other factors. There are technical difficulties of design and construction. Each project has its particularity. The technology of floating photovoltaic power stations is still developing both in domestic and abroad. Subject to the impact of the construction environment, the cost of floating photovoltaic power station projects is often higher than that of ground photovoltaic, and the cost proportion of floating materials in the whole project is relatively high. Combined with an actual design case, this paper studied and analyzed the selection of floating body type of floating photovoltaic power station and different layout schemes of photovoltaic power unit from the perspective of project cost. The universal conclusion is contributed to a better design scheme.

This paper takes the influencing factors of substation project cost as the input variable and the cost evaluation value as the output result, and then uses the neural network algorithm to evaluate the cost. Considering the shortcomings of neural network algorithm, genetic algorithm (GA) is used to optimize the neural network to realize a stable and effective evaluation of substation project cost. The simulation is carried out in Matlab environment, and the proposed algorithm is compared with the traditional BP neural network. The results show that the model improved by GA has more remarkable effect in application, and can guide the project cost management.

Traditionally, the research on the breakdown performance of XLPE mostly adopts experimental methods. This article attempts to study the influence of moisture on the breakdown performance of XLPE and the mechanism of action based on first principles and calculation methods. The Monte Carlo method was used to build a pure XLPE amorphous region unit cell model and simulate the damp condition of XLPE by adding water molecules. The geometry optimization and single point energy and band structure calculation were performed for above models by using the plane wave pseudopotential method. Some parameters, including the maximum displacement, maximum stress, total ground state energy, band gap and bond length, were calculated to study the effect of moisture on the breakdown performance of XLPE insulation. The calculation and analysis results show that for the cross-linked polyethylene model without moisture, as the external electric field intensity increases, the total energy gradually decreases, the band gap will be narrower, and the chemical bond length at the cross-linking position becomes larger. While the electric field intensity reaching a certain level, some C-H bonds and C-C bonds will be separated. It is shown that the molecular structure of XLPE was destroyed under strong electric field, and the breakdown performance of XLPE material deteriorated. Compared with the above model, for crosslinked polyethylene model containing water, the ground state energy decreased significantly, band gap was narrower, indicating that the existence of water molecule can reduce XLPE breakdown strength. The total energy and band gap show the declining trend and chemical crosslinking position bond length is larger as well with the increase of electric field intensity.

Traditional harmonic state estimation methods are limited by few measurement devices, difficulty in obtaining accurate harmonic impedance, complex network topology, and changes in grid operation. These factors cause problems such as underdetermined measurement equations, non-global observable systems, and difficulty in extracting accurate coupling relationships between buses. This paper proposes a novel method based on an augmented generative adversarial network for harmonic state estimation. The efficient extraction of electrical image features by the neural network method is achieved by transforming the temporal sequence data into electrical images. The generator based on deep residual networks and the improved residual block structure are used to improve the feature learning capability of the generator. In addition, the loss function of the generator takes into account the difference between the real samples and the generated samples in the high-frequency component. The validity and accuracy of the proposed method have been verified by simulation analysis.

Electricity contract curve shapes and prices would affect stakeholders’ profits. However, as past contracts are traded merely in quantity, there lacks an evaluation method for curve contracts at the current market stage. This research establishes a mid-and-long-term contract curve pricing system that reflects electric energy value, green value, and regulation value for each period. The homologous pricing evaluation model can measure the contributions of power plants of various types, and corresponding results could serve as the basis for formulating contract guidance prices for certain curve shapes. This article takes the Ningxia region as an example to verify the scientific nature and effectiveness of the model in an area with high new energy penetration. Results show that the model can promote the distribution of contract values, guarantee the effective linkage between the mid-and-long-term market trading and spot market trading, and provide a reference for the design of power trading supporting mechanisms.

A single-phase transient fault occurred at the forward outlet of the power incoming line in a 220kV user substation. After the line protection acted then the line switch on this side tripped, the B-set ratio differential protection of the 1# power transformer acted, while the A-set protection did not. The analysis shows that due to the voltage rise after the external fault is removed, the transformer produces restorative inrush current. In addition, when calculating the second harmonic content in the differential current, the B-set differential protection does not use the real differential current, but constructs a "virtual differential current" with zero sequence current. Theoretical analysis and data verification show that using the "virtual differential current" to calculate the second harmonic content can not more effectively identify the magnetizing inrush current, but may cause the braking failure of the protection and then misoperation.

With the proposal of "dual carbon" goal, the installed capacity of new energy is increasing rapidly, but the randomness and unpredictability of new energy affect the security of power grid. The stability of power grid requires the thermal power plant to carry out the task of peak regulation, but the thermal power plant to undertake the task of deep peak regulation is not high income, poor enthusiasm. Based on the operation rules of auxiliary service market in Northeast China, this paper studies the deep peak shaving task of energy storage system auxiliary thermal power plant. At the same time, the cost of all-vanadium flow battery was modeled and calculated, and the control strategy of charge and discharge limit of energy storage was adopted based on the depth peak shaving benchmark. The cost model and profit model of the energy storage system are constructed, and the economic analysis of the energy storage system in the combined fire storage system is carried out. Further explore the feasibility of energy storage system combined with thermal power plant peak regulation.

In order to solve the multidimensional energy flow optimal scheduling problem in integrated energy system (IES), this paper proposes an IES optimal scheduling method based on NSGA-II-MOABC. Firstly, an IES topology framework including electric and heat subsystems is constructed. Secondly, for the different subsystems in the system, the dynamic electricity price control strategy and the hierarchical energy supply control strategy based on the energy market are formulated to achieve the collaborative control of the overall system. Then the non-dominated sorting genetic algorithm-II (NSGA-II) and multi-objective artificial bee colony algorithm (MOABC) are improved by sorting and classifying the population crowding. A new algorithm named NSGA-II-MOABC is proposed and applied to the model of IES. Finally, the convergence of the algorithm is verified by simulation of example, and the optimal results of the model are analyzed from the energy efficiency and economic revenue. The result shows that multi-strategy collaborative control used in this paper can improve system energy efficiency, and optimal scheduling method based on NSGA-II-MOABC can raise system economic benefits from multiple perspectives.
