NOVELTY - The method involves determining network nodes (4), at which a voltage lies outside a desired voltage range. A voltage change that is required to return the nodes again into the desired voltage range, is determined. Collective change requirements for a reactive power and/or an active power of resources (1) are determined according to a predefined operation strategy based on the required voltage change. The voltage change is divided into portions used for determining the change requirements for the active and reactive powers. The collective change requirements are converted by the resources.    USE - Method for stabilization of voltage in an electrical distribution network i.e. low-voltage network (claimed), including resources such as feeders e.g. photovoltaic energy generating systems with and without energy storages, wind power plants, and block-unit heating power plants, and consumers e.g. battery-based controllable energy storage systems and intelligent energy managers, which control consumption and feeding of an entire household or a local network with a number of households.    ADVANTAGE - The collective change requirements for the reactive power and/or the active power of the resources are determined according to the predefined operation strategy based on the required voltage change, and the collective change requirements are converted by the resources, thus enabling determination of distribution of input for reaching a control objective of the resources based on a common control objective. The method provides the control objectives, for whose conversion performance of individual feeders is not sufficient. The method avoids losses by local overloading of the network, and evenly distributes effort and damages of individual resources among the resources. The method avoids an excessive demand of resources with a small power rating, and reduces communication effort between a central management unit and the resources.    DETAILED DESCRIPTION - The resources are photovoltaic systems. An INDEPENDENT CLAIM is also included for a device for voltage stabilization in an electrical distribution network.
