The data exchange between transmission and distribution system operators is more important than ever!
The reason for developing a system for Security Analysis and System Optimization (PSIsaso/ DSO 2.0) were the European network regulations which require the cooperation between Distribution System Operators (DSO), plant operators, and Transmission System Operators (TSO) in the European electricity network. In particular, the regulations include CACM, GLDPM, FCA VO, and SO-GL.
The DSOs must inform generation plant operators about pending infeed management measures.This enables the DSO to set up look-ahead models of their networks and to provide them to the TSO.
PSI is a competent partner at your side to meet the data exchange requirements.
We have developed a future-proof solution to meet these requirements. As a DSO, you can also significantly benefit from these.
Our system for Security Analysis and System Optimization PSIsaso consists of the two basic functionalities basic module and PCOM+ as well as the application modules GLDPM for the data exchange process specified in Germany, Network State Forecast for look-ahead network operations, and Redispatch for the realization of Redispatch 2.0.
For the realization of the associated requirements, it is necessary to expand existing control systems and to add new components. For this purpose, PSI has developed PSIsaso/DSO 2.0 which provides you with a modular, expandable, and therefore future-proof solution.

The DSOs must inform generation plant operators about pending infeed management measures.This enables the DSO to set up look-ahead models of their networks and to provide them to the TSO. The range of functions include:
Seamless handling of various file formats
Basis for additional network security applications
PCOM+ is used for exchange and archiving of time series. This module makes the forecast data which are processed in the SASO module available for documentation purposes or other uses (such as look-ahead network monitoring with day-ahead or 2-day-ahead time horizon) in your network control system. It includes following features:
Capacity calculation based on a standardized procedure for the electricity traded on the day-ahead and intra-day markets requires data exchange across networks. This is achieved with the following features:
For a realistic forecast of the future state of the distribution networks, it is important to know the state of the transmission networks.This objective is achieved with the following functions:
The Redispatch module provides continuous exchange of information related to the dispatch process between the network operators. For this process of mutual coordination of measures between network operators, the following functions are available:
With the increase of the decentralized energy generation, the importance of the usually static disconnection points in the network also increases. The "Decision support" module realizes dynamic optimization of the disconnection points which allows significantly better utilization of the entire medium and low voltage network while complying with the specified voltage bands. The objective of this optimization is to avoid additional network expansion measures.
The "Decision support" module also provides support for network security. Intelligent energy networks require intelligent security applications for configuration of the field components as well as the management of the control center and the exchange of the required data. Even security experts cannot easily detect slowly injected manipulations of the network. The AI algorithm developed by PSI FLS for pattern recognition detects irregularities which may appear irrelevant to human observers and which have no apparent effect on your current network status.
