  • Target Network Planning Target Network Planning

    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 Tried-and-tested user profiles are becoming outdated, and the predictability of load flows and network load is becoming an increasingly complex task.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.

    Specific services:

    • Assessing the current grid (grid topology, equipment characteristics, isolation points)
    • Determining the current and future transmission task
    • Modeling the grid in network analysis software (Neplan, Power Factory)
    • Simulating the load flows to determine weak spots and spare capacities
    • Developing a new grid structure concept
    • Detailed planning and specification of the target network
    • Factoring in efficiency requirements imposed by incentive regulation
    • Determining and comparing the technical and economic characteristics of the grid versions
    • Compiling an action plan for converting the present grid into the target grid
    • Developing a measurement concept for data- and forecast-based grid control
  • Process I&C and Network Management Process I&C and Network Management

    Process I&C and Network Management

    When constructing and rehabilitating environmental protection and process production facilities with their infrastructure, we handle all tasks involving automation technology including safety-oriented functions, for example up to SIL certification. This includes equipping the control rooms for process and operation management with state-of-the-art I&C systems and other ancillary installations.

    For load dispatch and network control centers in transmission grids and power distribution systems, we plan the grid control systems. For these planning tasks, likewise considered among others are higher-level decision and optimization functions; energy and distribution management systems (EMS and DMS); substation control systems; workforce and operations management systems (WFM, OMS); geographical and equipment information systems (GIS, EIS); and secondary and tertiary control in the power grid with associated telecommunications systems, including remote reading (smart metering) of meters in transformer substations and at retail consumers.

    In this connection, we also pay particular attention to the critical cybersecurity aspect of these systems in compliance with the current standards ISO/IEC 27001, DIN SPEC 27009 and ISO/IEC TR 27019, through support in the development and adoption of an information security management system (ISMS), and by systematic hardening of all system components.

  • E-mobility E-mobility


    The electrification of road traffic is beginning to gain momentum, as evidenced by the intensified expansion of recharging infrastructure and the growing range of electric vehicles on the market. Increasingly the transition to e-mobility is being driven in various countries not only by technological progress, but by political initiatives. These changing conditions are making e-mobility more attractive as it edges closer to making the leap from niche market to mass market.

    As a result of this, a new group of players are emerging on the power market, whose activities are having a significant impact on the infrastructure required for power generation and distribution. On the one hand, electric vehicles are consumers of electricity with the potential to cause consumption peaks and therefore bottlenecks. On the other hand, they are also storage devices that can provide valuable flexibilities in an environment in which a high proportion of the power is generated from renewable energies and is thus dependent on resource availability.

    Today we are faced with the challenge of merging the energy and transportation sectors and upgrading the energy infrastructure to bring it in line with the requirements of e-mobility. Our experts assist companies from both the energy and automotive industries in shaping this transformation process.

    Specific services:

    • Developing scenarios of electric vehicle penetration: number of electric vehicles, distribution of electric vehicles, charging power, number being charged, charging strategy, coincidence factor
    • Modeling power grids, present load flows and e-mobility scenarios in network analysis tools
