A Grid Operation Model: Resource Demand for an Adequate Quality of Supply

Based on the regulation of grid fees and the regulatory requirements on the quality of supply, grid operators attempt to find an optimal balance between costs and quality of supply. One main aspect of the quality of supply is the non-availability of supply, which strongly depends on the duration of the re-supply process and therefore on the availability of resources. Consequently, grid operators need to analyze the relation between a certain configuration of resources and the corresponding costs and quality of supply. Focusing on the re-supply process in mediumand lowvoltage grids, this paper presents a detailed grid operation model which allows to quantify this relation. Depending on legal, regulatory or strategic requirements, this model allows to evaluate and compare different configurations of resources and the resulting quality of supply.
