The future of energy supply is decarbonized, decentralized, and digital. The changed framework caused by the volatility of renewable infeed and the integration of electric mobility pose new challenges on the distribution network operators.
The new system structures require an efficient system management. This calls for a secure and reliable deployment of information and communication technologies in order to ensure the balancing and stability of the supply infrastructures.
Based on the Smart Operator Platform, PSI has developed a new kind of hybrid network controller (InGO) for multiple voltage levels - low-voltage and medium-voltage netzwork, which enables the integration of partially autonomous and decentralized network management into the network operations management in control centers. The fast and targeted congestion resolution by InGO provides effective and economical protection for the distribution network infrastructure.
InGO includes control and optimization modules for network automation, cascaded charging management for all levels, and an energy management system for medium-sized and industrial customers.
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" 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.
