	abstract = {Distribution system operators face more and more issues due the rapid spread of intermittent renewable energy sources on distribution grids. The most significant of these issues on the Hungarian distribution grids is the excess of voltage limits. In this paper sensitivity factors are defined to connect network voltage constraints and market-based flexibility products. A simplified network model is created based on the characteristics of Hungarian distribution grids for both medium voltage and low voltage investigations. Sensitivity factors for voltage control are calculated with both active and reactive power flows. Correlations between the effects of interventions on both different branches and voltage levels are examined. It is demonstrated that the effect of active and reactive power flows is primarily defined by the impedances of the lines. It is also shown that congestion zones can be created both per branches and voltage levels on radial networks, as the cross effects are insignificant. © 2023 IEEE.},

Tanulmányunkban számítógépes szimuláció segítségével megmutatjuk, hogy milyen hatással van a középfeszültségű elosztóhálózatra az elosztott energiatermelők és az aktív fogyasztók nagy mértékű jelenléte, majd use case-eket definiálunk a jelentkező feszültségproblémák megoldására. A definiált használati eseteket sztochasztikus szimuláció segítségével validáljuk, és hasonlítjuk össze.
		The exponential growth in the installed capacity of distributed generation and storage units and the increasing presence of DSM and e-mobility, which are becoming increasingly important for consumers, raise a number of issues for power system operators. In our study using computer simulation, we show the impact of the large presence of distributed energy producers and active consumers on the medium-voltage distribution network, and then define different use cases as possible solutions for the presented voltage problems. We validate and compare the defined use cases using stochastic simulation.},
