“…If the tap change proves insufficient, local control of the PV sources is started. In further work [55], the authors carried out field studies of the proposed method using PLC communication. Similarly, in [31], a method of joint control was proposed, through the operation of OLTC and reactive power control in the inverter.…”

Deterioration of voltage conditions is one of the frequent consequences of connecting an increasing number of photovoltaic sources to the low-voltage (LV) power grid. Under adverse conditions, i.e. low energy consumption and high insolation, microgeneration can cause voltage surges that violate acceptable limits. Research shows that the increase in voltage is the main limitation for connecting new energy microsources to the LV network and forces the reconstruction of the network. An alternative to costly modernizations can be the implementation of appropriate strategies for controlling network operation to maintain the voltage at the required level. The article presents an overview of the methods and concepts of voltage control in a low-voltage network developed so far to mitigate the undesirable phenomenon of voltage boosting. The focus was mainly on local methods—not requiring communication infrastructure—as best suited to the conditions of Polish distribution networks. Gathering the results of many tests and simulations carried out in different conditions and on different models allowed for the formulation of general conclusions and can be a starting point for further research on a control method that can be widely used in the national power system.

“…Therefore, more tailored solutions for LV circumstances are required. Several research projects investigate in state estimation and voltage control especially for LV grids [3][5] [6]. When communication failures occur, pseudomeasurements can be used for state estimation, leading to a decrease in estimation quality especially when multiple meters fail at the same time [4].…”

“…Within the project "SmartCityVillach -Vision Step I" [1] a novel voltage estimation concept was developed to support distributed voltage control in case of communication loss or delays. The voltage estimator was implemented as additional component for the voltage control environment which was developed within the "DGDemoNet SmartLVGrid" [2] [3] project, where different voltage control strategies were tested in three Austrian LV grids. In this predecessor project the MV/LVtransformer's tap position was controlled under consideration of actual voltage measurements from the grid provided by smart meters over power line communication.…”

This paper presents estimation strategies for voltage measurements developed to enhance the robustness of distributed voltage control in secondary substations in case of communication delays and failures. Different estimation concepts are described and benchmarked. The most promising concepts were implemented and validated in field tests in two low voltage grids for several months. Results from these field experiments and underlying simulations are shown and the impact of the estimation concepts on the voltage control process is discussed.
