As a result of the CO2 reduction target, millions of new generation plants and loads will be integrated in the distibution grid. The grid management of the future is therefore significantly different from the past. Key characteristics of distribution grids are increasingly small-scaled and distributed as well as customer-centric. The changed general conditions due to the volatility of regenerative feed-in and the integration of e-mobility pose new challenges for distribution grid operators. The safe and reliable use of information and communication technologies is absolutely necessary to ensure the balancing and stability of the supply structures.
The new system structures require efficient system management. PSI GridConnect offers a growing system for the progressive integration of active components for the digitalization of the distribution grid. With the visibility of possible bottlenecks via sub substation and grid monitoring, we offer so-called GridApps as a first expansion step. The resulting transparency allows the demand-oriented, economically sensible use of intelligent grid controllers in a second step.The technological basis is provided by the new hybrid cross-over voltage levels PSIngo gridcontrollers for low and medium-voltage grids, across voltage levels. This enables operating modes ranging from the assistive support of system operators to semi-autonomous or independent grid control. PSIngo protects the distribution network infrastructure effectively and cost-effectively by quickly and specifically eliminating bottlenecks. PSIngo includes control and optimization modules for grid automation, cascaded charging management and a micro grid for industrial customers and an energy management system for small-to-medium enterprises.
InGO communicates with the upstream network control center using standardized telecontrol protocols. The decentralized controller transmits operating parameters, network states, and aggregated values to the control system. In the opposite direction, setpoints or active/passive switching operations are sent to InGO. In addition, the current breaker positions and the current set of parameters are exchanged dynamically between the control center and InGO.
The transformation process of the energy transition makes the planning process often unpredictable. Nevertheless the long-term objective of a decarbonized and decentralized distribution network is a political mandate. From the network operators’ point of view, an economically feasible and risk-free approach with maximum flexibility is required. The first step of protecting your investments with InGO is the integration of measurements from the "depth of the network" for more transparency and improved planning. The next step is the successive rollout of intelligence at the required locations.
The motto is "Decentral connectivity" which means the maximally autonomous execution of monitoring and control tasks with simultaneous connectivity to the upstream controller instance. This ensures integrated operations across all voltage levels to comply with the system limits while being able to receive setpoints from the control center. The interactive design and the listening mode of the InGO security proxy provide your smart grid projects with (n-1) security and the appropriate fallback levels.
The increasing market synchronization of the distribution network, including power plants, markes artificial intelligence crucial for forecasting and managing the potential network dynamics. InGO has already gained relevant field experience with network structure detection using an AI environment and a fixed set of measurements.
Already today, KPIs can be used in control center as upport tools in order to avoid non-permitted network situations.
InGO offers coordinated network management in order to avoid malinvestments . This provides an economically realistic alternative to conventional network expansion.
In terms of network planning, InGO is an economic standard system object similar to conventional network expansion methods. The appropriate tools for integration and project design are available to network planning and thus support staff.
"Smart grid ready" means an integrated project rollout covering everything from reliable acquisition of measurements for monitoring and analysis to automatic patch and device management. Both the initial rollout and the actual operations are supported.
InGO is operated as an integrated subsystem of the network management process and supports the control center on all distribution network levels.
