“…The energy system in Europe is undergoing a far-reaching transformation on multiple fronts: generation from variable renewable energy sources, such as wind and solar power, is growing due to the imperative of tackling climate change; electricity provision has been unbundled and liberalised, raising complex Table 1: Standard line types for overhead AC lines [23] 4; conclusions are drawn in Section 5.…”

PyPSA-Eur, the first open model dataset of the European power system at the transmission network level to cover the full ENTSO-E area, is presented. It contains 6001 lines (alternating current lines at and above 220 kV voltage level and all high voltage direct current lines), 3657 substations, a new open database of conventional power plants, time series for electrical demand and variable renewable generator availability, and geographic potentials for the expansion of wind and solar power. The model is suitable both for operational studies and generation and transmission expansion planning studies. The continental scope and highly resolved spatial scale enables a proper description of the long-range smoothing effects for renewable power generation and their varying resource availability. The restriction to freely available and open data encourages the open exchange of model data developments and eases the comparison of model results. A further novelty of the dataset is the publication of the full, automated software pipeline to assemble the load-flow-ready model from the original datasets, which enables easy replacement and improvement of the individual parts. This paper focuses on the description of the network topology, the compilation of a European power plant database and a top-down load timeseries regionalisation. It summarises the derivation of renewable wind and solar availability time-series from re-analysis weather datasets and the estimation of renewable capacity potentials restricted by land-use. Finally, validations of the dataset are presented, including a new methodology to compare geo-referenced network datasets to one another. challenges for the efficient design and regulation of electricity markets; the need to decarbonise heating and transport is driving electrification of these sectors; and finally energy markets are being integrated across the continent [1].To study this transformation, accurate modelling of the transmission grid is required. The need to take account of international electricity trading and the possibility of smoothing variable renewable feed-in over large distances (wind generation has a typical correlation length of around 600 km [2]) mean that models should have a continental scope. At the same time, high spatial detail is required, since national grid bottlenecks are already hindering the uptake of renewable energy today [3], and given persistent public acceptance problems facing new transmission projects [4], severe grid bottlenecks will remain a feature of the energy system for decades to come.Currently there is no openly-available model of the full European transmission network with which researchers can investigate and compare different approaches to the energy transformation. The transmission grid dataset provided by the European Network of Transmission System Operators for Electricity (ENTSO-E) for the 2016 Ten Year Network Development Plan (TYNDP) [5] is rendered unusable by restrictive licensing, the exclusion of Finland, Norway and Sweden, and a lack of geographic...

“…Assuming that the population of every cluster is identical and factoring in the average parameters identified, a possible low voltage grid was selected. Since suburban low voltage grids are generally characterized by a rural structure [18], the substation was integrated in the center of the area selected and the different lines were laid parallel to the existing infrastructure. The final low voltage grid (see Figure 2) consists of four individual lines with a total of fifty-seven households and two farms.…”

The objective of this study is to analyze the influence of electrochemical energy storage systems on low voltage grids with high penetration of renewables (RES), mostly photovoltaic power stations (PV). Furthermore, it compares the integration of energy storage systems (ESS) with other alternative solutions economically. It also presents the simulation results for a German power network in a suburban area of Bavaria. In the case study, the ESS are used to reduce overloading of electrical equipment (e.g. power cables and transformers) caused by fluctuating generation of integrated RES. The simulation results reveal that economic use of energy storage to support the grid is feasible when it is accompanied by a specific incentive. The storage tariff necessary for this is comparable with the initial Renewable Energy Act tariff for renewables, thus making this a realistic method for facilitating the use of EES that benefits the grid

“…Authors, like Oeding et al [6], present tables for positive and zero sequence impedance parameters for different cable types, intended for rough calculations of minimum and maximum fault currents. Based on the assumption of equal mutual inductances between phases-which seems unrealistic for four-core cables (see Figure 1)-these parameters do not seem to be suitable for modeling of LV systems.…”

“…Based on the assumption of equal mutual inductances between phases-which seems unrealistic for four-core cables (see Figure 1)-these parameters do not seem to be suitable for modeling of LV systems. Furthermore, the underlying assumptions regarding system grounding are derived from transmission grids [6] and seem questionable for German LV grids.…”

Modeling of German Low Voltage Cables with Ground Return Path

In this contribution, measurement data of phase, neutral, and ground currents from real low voltage (LV) feeders in Germany is presented and analyzed. The data obtained is used to review and evaluate common modeling approaches for LV systems. An alternative modeling approach for detailed cable and ground modeling, which allows for the consideration of typical German LV earthing conditions and asymmetrical cable design, is proposed. Further, analytical calculation methods for model parameters are described and compared to laboratory measurement results of real LV cables. The models are then evaluated in terms of parameter sensitivity and parameter relevance, focusing on the influence of conventionally performed simplifications, such as neglecting house junction cables, shunt admittances, or temperature dependencies. By comparing measurement data from a real LV feeder to simulation results, the proposed modeling approach is validated.
