With the increasing penetration of renewable energy in the power grid, coordinated operation of multi-provincial grid is an effective measure to improve the renewable energy accommodation capacity of power grid. It is difficult to guarantee that the active power of tie lines is equal to their dispatching plan by calculating the power flow distribution in the whole network. Therefore, a partition control method of power balance of multiͬ provincial grid with high penetration of renewable energy is proposed. Due to multiple load deviation adjustments and AC power flow calculation of each province, the active power of tie lines can be ensured to be equal to their dispatching plan. The proposed method is composed of two sectors: distribution method of load deviation of each province with a high proportion of renewable energy, in which the balanced relationship of power generation and consumption of each province is established;accurate estimation method of transmission loss of each province under the future operation mode based on prediction and correction, in which the calculation error of unbalance caused by the estimation error of transmission loss can be further reduced. A case study based on an actual multiͬ provincial grid demonstrates the effectiveness of the proposed method. © The Institution of Engineering and Technology.

The hybrid HVDC transmission system combines the advantages of the line commutated convertor (LCC) and the voltage source converter (VSC) which has great development prospect. Given the uncertainty and complexity in parameters tuning of control modules, this paper introduces a novel robust Multi-Objective Optimization via Evolutionary Algorithms (RMOEA). By searching pareto optimal solutions and robust solutions separately, each region's convergency and diversity performance under perturbance are enhanced appreciably. The improved RMOEA is used to optimize the PI parameters in the rectifier side controller and the inverter side dq axis decoupled dual-loop controller simultaneously. The simulation is implemented jointly by MATLAB and PSCAD software and the experiments results show that compared with the other optimization algorithm, the proposed RMOEA verifies the effectivity of improvements on robustness under the disturbances and tracking ability of preference. © 2019 IEEE.

The transient stability mechanism of grid-following inverter (GFL-inverter) and grid-forming inverter (GFM-inverter) in the power system has been extensively studied respectively, whereas the integration of GFM-inverters and GFL-inverters into the grid unavoidably change the transient stability of the power system. This paper aims to analyze the transient stability for the mixed-GFM-GFL power system (MGGPS). The equilibrium point of the MGGPS system is analyzed. The large-signal model of the system is established. Based on this model, an analysis of the transient stability is carried out. It is revealed that the change of GFM-inverter terminal voltage will move the position of GFL-inverter equilibrium points, and the increase of GFL-inverter terminal current will enhance the transient stability of GFM-inverter. With the simulation of phase portraits, the aforementioned transient stability mechanism is proved. © 2021 IEEE.

With the increasing penetration of distributed energy resources in distribution network, it is necessary to strengthen the research on optimal power flow control of intelligent distribution network. Aiming at the characteristics of distributed energy resources decentralized access in intelligent distribution network, a zonal collaborative control structure of intelligent distribution network based on multi-agent system (MAS) theory is designed. An optimal power flow model of the intelligent distribution network is established, which aims at minimizing the cost of power consumers, voltage deviation and power losses. The intelligent single particle algorithm is used to optimize power flow in the intelligent distribution network. The distribution system of the intelligent distribution network laboratory is analyzed to verify the effectiveness of the model and the algorithm. © 2019 IEEE.

As the increasing penetration of inverter-based distributed generations (DG) reduces the inertia of the power system, the stability of the system under small disturbances is threatened. grid-forming (GFM) inverter, which can simulate inertia, damping and droop characteristics, is one of the most effective solutions. Virtual inertia and damping coefficient have important effects on the performance in primary frequency modulation. This paper presents an explicit and universal small-signal model for multi-GFM system based on the Newton-Raffson power flow algorithm in polar coordinates to realize the optimal design of virtual inertia and damping coefficient. The validity of the proposed model is demonstrated by comparing with the simulation model, and the effect of virtual inertia and damping coefficient on frequency response is analyzed in the end. © 2021 IEEE.

Extreme weather, such as cold waves and frosts, can significantly impact the output of wind farms. To address this issue, this paper proposes a short-term power prediction and correction method suitable for wind farms during extreme weather, based on the K-nearest neighbor algorithm and multiple linear regression model. By verifying that wind power output is affected by wind speed, temperature, humidity, wind power kurtosis, and other factors, the K-nearest neighbor algorithm is used to obtain the sample set of similar days on the day to be measured. The regression model of influencing factors and output errors is established to improve the power prediction accuracy. A wind farm in northwest China is used as a test example to verify the effectiveness of the output correction method. © 2024, state grid Electric Power.

With the rapid development of distribution network automation and the construction of DC distribution network and AC / DC hybrid distribution network, the network operation mode is more flexible. If the distribution network wants to realize rapid load transfer, such as the connection of power supply, upstream and downstream fault isolation signals and other node states need to be quickly identified. At present, the node status identification of distribution automation is basically completed by the master station. However, the master station has poor real-time transmission of status information, which is generally in seconds or minutes, and can not meet the demand of real-time load transfer. In this paper, a distributed real-time transmission method of AC and DC distribution network node status is constructed for distribution automation system. Based on IEC61850 goose communication protocol, the real-time transmission of node status is realized in distribution automation terminal. In this method, the positive direction of each tie switch is defined, which is independent of power flow direction, and the tie switch is distinguished along the user-defined positive direction When multiple tie switches have the same upstream node, they are each other's t nodes. Each tie switch needs to be equipped with a distribution automation terminal with goose communication capability. According to different control strategies, the distribution automation terminal can realize millisecond level node state transmission step by step. Node state can be divided into unconditional transmission state and conditional transmission state. The distributed real-time transmission technology of distribution network node state proposed in this paper has been successfully applied to Tongli integrated energy service The center and Suzhou medium and low voltage DC project lay the foundation for the realization of loop closing, loop breaking control, fast fault isolation and power transfer control strat

Traveling wave fault location is very important for high voltage direct current (HVDC) transmission lines. The attenuation and distortion of traveling wave in HVDC transmission lines and secondary circuits will have non-ignorable negative impact on traveling wave fault location. In this paper, the attenuation and dispersion characteristics of traveling wave at different fault distance are simulated and analyzed. The further attenuation and distortion of traveling wave in the secondary circuit are studied by physical model. The problems of traveling wave reflection caused by the secondary cable and signal interference caused by strong electromagnetic interference are analyzed. Through the analysis of the whole process of traveling wave propagation and acquisition, the necessity of on-site acquisition of traveling wave signal for HVDC transmission line is proved. In this paper, the system scheme and key technology of on-site acquisition of traveling wave signal for HVDC line are given, and the technical feasibility of this scheme is stated. © 2021, Springer Nature Singapore Pte Ltd.

With the implementation of China's "carbon neutral, carbon peak"dual carbon target action plan and the construction of a new power system, access to a high proportion of new energy and microgrid has changed the function and form of the distribution network. The current capacity of the distribution network to absorb a high proportion of new energy cannot fully meet the needs of future development. Through rational planning, the carrying capacity of a distribution network for new energy can be improved, operation efficiency can be improved, and expansion investment can be delayed. Therefore, based on the analysis of the current typical network architecture of the distribution network, combined with the development trend of the AC/DC distribution network and the development trend of a high proportion of new energy penetration, this paper puts forward the future architecture and network shape of the AC/DC distribution network, focusing on the short-term, long-term and cellular AC/DC distribution network shape characteristics. It also discusses the influence of Photovoltaic (PV) permeability level on the grid configuration selection of AC/DC distribution network. Finally, it discusses the problems worthy of attention in the future planning of AC/DC distribution networks. © Published under licence by IOP Publishing Ltd.
