After China clearly put forward the goal of carbon peak and carbon neutralization targets, the clean energy transformation has accelerated. Under the background of large-scale development of renewable energy, high-voltage DC (HVDC) and ultra-high voltage DC (UHVDC)transmission become more effective way to transmit the resources of renewable energy from rich areas such as northwest and southwest to economically developed areas such as North China and East China. It is an important means of realizing the optimal allocation of resources through long-distance power transmission. This paper proposes an optimal power allocation scheme for DC transmission lines, which takes the minimum grid power as the objective function, focusing on the constraints such as the proportion of renewable energy and power constraint rate. The scheme adds the calculation method of economic analysis and carbon emission level, which gives a better understanding for result selection. Finally, a case study is performed by using the proposed optimal power allocation scheme. Taking the typical daily output as an example, it can be seen that the scheme not only meets the load demand, but also improves the consumption level of renewable energy.

The polyimide (PI) film is used as the internal insulation system in the high-temperature superconducting transformer due to its excellent mechanical and electrical performance. Many researchers had found that nanoparticle mixing can improve the polymer’s insulation properties. The partial discharge(PD) will induce the deterioration and even breakdown of the insulating materials. In the paper, the PI films modified by nano-A12 O3 were prepared in situ polymerization. The particle size of Al2 O3 nanoparticle used in this research is 10 nm, and the mass fraction is 1wt%, 3wt%, 5wt% and 7wt%, respectively. The volume resistivity, surface resistivity and partial discharge initial voltage (PDIV) are measured in liquid nitrogen(LN). The experimental results indicate that adding of 3wt% nanoparticle is the optimum ratio to suppress the PD in the PI films.

Water tree is one of the important factors that affect the service life of XLPE insulation cable and seriously threaten the safety of cable operation. In order to study the electric field distortion and Maxwell stress distribution characteristics considering water tree under different circumstances, the paper takes position, length and dispersion into consideration, and then a cable insulaton model with water tree defects under different conditions is established in the finite element simulation software. By applying a fixed voltage on both sides of the insulation, the axial electric field intensity of water tree is scanned, the maximum electric field intensity in the insulation is counted, and the influence characteristics of water tree on the electric field distortion of cable XLPE insulation are studied. At the same time, the Maxwell stress caused by electric field distortion is calculated, and the maximum axial stress of water tree is extracted and analyzed. The results show that when the size is approximately the same, the electric field distortion caused by Inner dispersed water tree is significantly higher than that on Outer dispersed water tree, and the electric field distortion caused by the Butterfly-shaped water tree whose size is approximately twice that of the dispersed water tree is between the two; The effect of length and dispersion on electric field distortion varies with water tree type and location.In terms of stress, the Maxwell stress caused by the Inner dispersed water tree is greater than the Outer dispersed water tree with approximately the same size and the Butterfly-shaped water tree with approximately twice the size. The increase of length is conducive to the reduction of the maximum Maxwell stress caused by the dispersed water tree.

In recent years, load frequency control (LFC) systems employ open communication networks to meet the requirement of modern power system communication. However, some new risks were introduced into the LFC system, such as information staleness. The communication delay, which is a packet-centric metric, is used to portray the degree of information staleness in the existing works, whereas it cannot fully capture the freshness degree of information updates. In this paper, age-of-information (AoI) is introduced to describe the freshness of the whole information update process. An AoI based stability criterion for sampled-data LFC systems is formulated. Results show that the LFC stability is dependent on AoI and the delay-dependent criteria is a special case of the AoI- dependent one.

Under the Background of ‘Carbon peaking and Carbon neutrality’ goals, with the rapid development of clean energy, power system is gradually transforming to low-carbon. The proportion of distributed photovoltaic in the distribution network increases rapidly, and the uncertainty of its output and the randomness of the access scheme can easily lead to dramatic changes in line power flow and bring about operational safety problems. Aiming at the problem that high proportion of distributed photovoltaic access affects the safe and stable operation of distribution network, this paper proposes a distributed photovoltaic acceptance ability evaluation method based on voltage sensitivity and multi-scenario power flow simulation. The method uniformly generates the possible access scheme of distributed photovoltaic in the network and simulates the multi-power flow. Finally, by comparing the peak voltage of each scheme, the distributed photovoltaic carrying capacity of distribution network is evaluated. Taking IEEE 14-bus system as an example, the results show that the proposed method can effectively solve the calculation problem of distributed photovoltaic carrying capacity of distribution network.

In this paper, a novel flux-intensifying flux- controlled permanent magnet motor (FI-FCPMM) is proposed. This motor mainly realizes flux-intensifying ($L_{d}gt L_{q}$) and controls the air-gap flux, thus improving the flux-weakening ability and reliability of the motor. This paper analyzes the structure and working principle of the FI-FCPMM, and then makes a performance comparison with the conventional interior permanent magnet motor (CIPMM). The results show that the performance of the FI-FCPMM is better than the CIPMM in control, torque, weak magnetic capacity, noise and constant power output capacity, and it also verifies that the FI-FCPMM has a wider speed range than the CIPMM.

The SEPIC converter, as a high order DC-DC converter, has rich nonlinear phenomena under some conditions. Memristor, as a special nonlinear device, is widely used in modern research. In this paper, a new type of SEPIC circuit with memristive load and front inductor current control is constructed. First, the state equations of the two working states in continuous current mode (CCM) are derived. The bifurcation diagram of inductance current and phase diagram of different planes under different bifurcation parameters are simulated by MATLAB. It is found that the converter with memristor load has a wider range of operation at period-1. Secondly, PSIM was used to build a circuit model with the same parameters, and the simulation results were consistent with those obtained by MATLAB. Finally, for system chaos caused by parameter changes, the method of ramp compensation is introduced to effectively suppress the chaos.

The internal decomposition gases of SF6 internal gas insulation equipment is closely related to the insulation state of the equipment. According to the relevant regulations, CO is an important component, and its concentration information can be used as the basis to judge the internal insulation state of SF6 equipment. Gas detection based on photoacoustic spectroscopy is an effective method for current line monitoring. In this study, the distributed feedback semiconductor laser was used as the light source and the interferometer cantilever acoustic sensor was used as the acoustic sensor to set up the photoacoustic spectrum detection device. The CO molecular spectral line of 2.33 $mu$m was selected as the research object to detect CO by photoacoustic spectroscopy, and the pressure characteristics of the photoacoustic signal is studied. The results show that the detected signal has high stability and a good linear relationship with gas concentration. The minimum detection limit of CO in SF6 gas is 5.1 ppm, and the photoacoustic signal detected by interferometric cantilever excited by CO decreases with the increase of pressure, which is mainly caused by the decline of the response ability of interferometric cantilever with the increase of pressure.

With the continuous development of electric vehicles (EVs), the charging load will exert more pressure on the regional power grid. The higher penetration may intensify the peak-valley difference and force the distribution transformer to be overloaded. This paper proposes a grouping strategy and day-ahead scheduling method of EVs participating in peak shaving. It fully considers the match between the resource characteristics of EVs and load regulation requirements of the grid to form a grouping method, in order to improve the performance as well as reduce the difficulty in plan generating process. Combined with the improved particle swarm algorithm, a day-ahead plan for EVs to participate in peak shaving is generated. Through the case studies, the strategy proposed is proved effective in optimizing the peak shaving performance and reducing the calculation amount of the plan generation process.
