Principles for the planning and operation of urban energy systems of the future

Together with several project partners in Germany – University of Wuppertal, Stromnetz Berlin, enercity Netz, Erlanger Stadtwerke AG, Rheinische NETZGesellschaft mbH, SachsenEnergie AG/SachsenNetze and Stuttgart Netze – a team of Siemens PTI consultants analyzed more than 4,000 high, medium and low voltage networks and several thousands of planning scenarios. The result of three years of intense research: a new guideline for the planning and operation of urban energy systems, covering, e.g.:

· Scenarios for conventional loads, emobility and heat pumps

· Simultaneity factors and regional distribution of new loads

· Application and effects of measurements such as load and charging management or the adaptation of standard cable sizes

· … and 24 planning and operation principles

The handbook is available in German under this link. If you are interested in finding out more about the results of this research project, contact us – we will be happy to share the insights with you.

Distribution grid planning

Developing future-proof power distribution systems

Distribution System Operators (DSOs) are in the center of today’s transformation of the energy system towards systems characterized by new loads and fluctuating, bi-directional power flows imposed from massive renewable generation. Despite these developments, the existing principles of an efficient, economic and sustainable energy supply remain as important as ever. 

Handling the immense amount of data which is available on the low and medium voltage grids creates disruptive opportunities and risks. Existing principles and guidelines have to be reviewed, and innovative and integrated infrastructure planning becomes more and more important. Backed by years of experience from a wide range of projects conducted all over the world, Siemens PTI supports DSOs in all aspects of distribution network planning, development and optimization.

EWR reviews the planning of its medium-voltage grid: Target grid planning and electromobility stress test (ew 2-3 / 2021)

With the electrification of private transport, load forecasting and eMobility Stress Tests are increasingly moved into the focus of target network planning. Siemens applied these methodologies to revise the planning of the medium-voltage grid of EWR GmbH. The planning was extended to allow that load forecasts for the individual target years 2025, 2030 and 2035 and automated evaluations of network calculations can be carried out.
