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.

These problems cannot be handled economically effective with traditional network operation and maintenance solutions. Aim of this paper is to give an expert analysis in consideration of possible new technologies from system operator point of view bearing in mind the regulatory environment. Analytical methods and simulation were used to evaluate the effects of these technologies and trends. 14 network effects and 9 different technologies were examined. As a result a revised microgrid definition will be introduced and 5 proposed interventions are formulated. © 2019 IEEE.
