“…The purpose of adjusting the output voltage of the low-voltage winding at any time is realized by switching the tap switch at any time and adjusting the tap position of the high-voltage winding under the condition of carrying load to ensure the quality of the output voltage. Yuan et al [45] analyze the principle of the double-core symmetrical phase-shifting transformer (DS-PST) and the application of trend regulation, which can transfer the active power transmitted by high load-rate lines to low load-rate lines so as to make the distribution of system trend more balanced and effectively improve the transmission capacity of the power system. Changing the control strategy of the on-load tap changer (OLTC), the first controller (ANFIS-OC) in this strategy solves the voltage overrun problem due to low X/R ratio and PV distributed generation by calculating the OLTC reference voltage based on the minimum and maximum voltage magnitude of the grid [46].…”

Distributed photovoltaic (PV) in the distribution network accounted for an increasing proportion of the distribution network, and the power quality of the distribution network of the power quality problem is more and more significant. In this paper, the voltage regulation methods for low-voltage distribution networks containing high-penetration PV are investigated. First, the working principles of the four voltage control methods are introduced: energy storage system configuration, regulating the reactive power output of PV inverters, restricting the active power output of PV, adjusting the switching positions of on-load regulator trap changer and distribution network reconfiguration, and then, in combination with the recent related research, the optimization of each method is compared horizontally with its respective concerns and characteristics. The optimization of each method is compared horizontally with the recent studies to find out the focus and characteristics of each method, and the shortcomings of each method are explored. Coordinated voltage control through multiple flexibility resources has become the mainstream voltage regulation scheme, and distribution network voltage regulation is considered from the perspective of flexibility resources. The three types of flexibility resources, namely, source, network, and storage, have been widely used in distribution network voltage regulation. Although load-side resources have become one of the main regulation resources of the new type of power system, the current study introduces less about the participation of load-side flexibility resources in voltage regulation of LV distribution networks and advancing the application of load-side resources in voltage regulation of LV distribution networks is the focus of future research. Then, the important role of load-side flexibility resources in voltage regulation is described in three parts, namely, the important role of load-side resources, the development trend, and the suggestions for promoting the coordination of source-network-load-storage flexibility resources, aiming to promote the application of load-side resources in voltage regulation in LV distribution networks, and the suggestions and programs are proposed for the technological challenges faced by voltage regulation. In the context of today’s new power system emphasizing the interaction of source, network, load, and storage, new technologies and methods for solving voltage problems in LV distribution networks are prospected, with a view to providing certain reference value for the actual operation and optimization of distribution network systems.
