Target network planning of distribution grids
As a result of increasingly distributed power generation, the infeed of power is shifting from transmission grids to distribution grids which are becoming distributed power plants in which the direction of the current flow can reverse. Energy is also increasingly being stored in batteries to optimize self-sufficiency, while electric vehicles are being recharged more and more. This is fundamentally changing the role of distribution grids. Tried-and-tested user profiles are becoming outdated, and the predictability of load flows and network load is becoming an increasingly complex task. As a result, new principles are required for planning and operating distribution grids.
For the dimensioning of a grid, we assess the future supply task based on various scenarios, such as an expansion in renewable energies or electromobility, create a model of the grid and simulate the load flows. Based on the results and the efficiency requirements imposed by incentive regulation, we develop a new grid structure concept for you and devise a detailed target network plan that ultimately results in an action list for reshaping the grid.
We also assist you in implementing smart load management, which can significantly limit grid expansion costs. In doing so, the aim is to successively develop the network into a smart grid and to include the necessary sensor systems in the grid planning.
