“…Finally, the reclosing configuration method considering distributed power supply access is given, which has good practical value. Based on the definition and characteristics of distributed power generation, literature (Yongfei et al, 2016;Xiao, 2018) explores the influence of distributed power access on relay protection of distribution network, but the content is theoretical and no specific simulation is used to verify the applicability of the proposed scheme. Literature (Azeroual et al, 2022) proposed a new method for fault location and autonomous recovery of distributed distribution system based on multi-agent system, and tested the proposed protection method by using the openloop feeder distribution system in Kenitra, Morocco.…”

With the rapid development of the new energy industry, distributed generation (DG) is connected to the power grid on a large scale, and the traditional relay protection scheme is no longer suitable for modern power systems. In order to solve this problem, this paper establishes a mathematical model of the equivalent circuit of distributed photovoltaic power supply according to the external characteristics of photovoltaic cells, and analyzes its volt-ampmeter characteristics and voltage output characteristics of power supply. On this basis, it analyzes and puts forward the control mode of DG when the distribution network is faulty. On the basis of the study, this article has double feeder distribution network as an example, the analysis when the line fault occurring at different extents of DG connected to different position on the influence of the distribution network current protection, the results show that when answering DG side in the feeder bus for distribution network of current protection, pick a smaller effect on both ends of feeder, has a certain symmetry. Finally, the accuracy of theoretical analysis is verified by establishing a simulation model in PSCAD.

“…In recent years, countries have rapidly developed clean renewable energy, and the proportion of installed capacity of photovoltaic (PV) power systems in the power system has been rising. Since the output power of the PV power system changes with the weather change, the grid connection of a large-scale PV power system will affect the stability and reliability of power grid operation [1][2][3][4][5]. The installation of the battery energy storage station (BESS) in the grid-connected PV power system to stabilize their output power fluctuations.…”

Aiming at the problem that the grid-connected power fluctuation of the photovoltaic power system affects the stability of grid operation, a multivariable fuzzy coordinated control strategy for photovoltaic grid-connected power fluctuation based on super-capacitor and battery is proposed. First, a multivariable fuzzy controller is established based on the grid-connected estimated fluctuation power of the photovoltaic power system and the current energy state of charge of super-capacitor and battery. The fuzzy relational matrix is used to introduce interaction effects of inputs into the fuzzy control, the fuzzy relation matrix is established by multiplying with weights, and the time constant of the low-pass filter is adjusted to coordinate the distribution of fluctuating power between different energy storage in real-time. Second, according to the SOC variation of HESS, a super-capacitor fuzzy controller and battery fuzzy controller are established to modify the charging and discharging instructions of battery and super-capacitor. The charging and discharging power of the energy storage are constraints to optimize the charging and discharging power of the energy storage, and the energy state of the HESS is updated in real-time. Finally, an overall example analysis of fuzzy coordinated control is performed to verify the effectiveness of the proposed control strategy.
