The energy transition presents electricity grid operators with immense challenges that need to be solved quickly if the switch to a climate-neutral energy supply is to succeed in the near future. New consumers are being connected to the electricity grid everywhere - from domestic air conditioning and heat pumps to charging systems for electric vehicles. At the same time, more and more small power generation units are being added that feed green electricity into the grid in order to meet the increased energy requirements of consumers.
This development requires an intensive examination of the grid load in the low-voltage range, which has so far only been inadequately determined. On the one hand, there is a lack of measured values and, on the other, the lower the basic quantity, the less predictable the load forecast. The central question is therefore: How can the power to be provided for individual consumers be determined systematically and taking realistic simultaneities into account?
This is precisely where the book comes in and develops solutions for how the power to be provided can be determined pragmatically and efficiently using conventional and alternative planning tools. It is aimed at specialists and managers in trade, industry and public administration as well as those interested in R&D and teaching who deal with the topics of load or power determination, building cost subsidies and network calculation.
A particular highlight of the book is a newly developed method for determining the grid load for any number of consumption points: the load profile calculation.
The load profile calculation gives the currently used static load flow calculation a third dimension, takes simultaneity into account in the calculation and shows the load profile over time. Loads for 1...n households and charging stations can be determined using a simple spreadsheet - no complex iterations are necessary. For all other consumer groups, load estimation approaches are presented that also serve to improve the dimensioning of operating resources. The load profile calculation is therefore suitable for all types of application: from distribution networks and industrial networks to building networks, area networks, street lighting networks and many more.
The book can be used for:
- the determination of the power to be provided for an individual grid connection,
- the determination of the power of one to several grid connections in a low-voltage local grid under fuzzy input conditions,
- the design of power supply units or areas,
- the consideration of load flow and voltage drop,
- the allocation of services for determining the construction cost subsidy.
