In order to increase the supply security, information about the network capacities which are available now and in the future is necessary. This requires a comprehensive data basis in order to achieve a pan-European overview.
Following the respective EU regulation, the German transmission system operators (TSO) have decided in 2017 on the procedure for supplying the distribution network data (topology, generation, and load data) to the TSO. This methodology is called "Generation and Load Data Provision Methodology" (GLDPM). As of January 2018, Distribution system operators (DSO) must meet the new requirements.
The data exchange between transmission and distribution system operators is more important than ever!
The information about the available capacities is the basis for assessing the supply security and determining measures which may be required. The transmission system operators have been successfully exchanging data between companies. For example for the minute reserve, the capacity forecast enables compensation of frequency deviations due to volatile generation and demand.The expansion of the decentralized energy generation in low voltage networks up to medium voltage networks temporarily results in backfeed to the TSO networks. Only if the entire capacity is known to the TSO can a realistic forecast can be generated and the established supply quality be ensured in the future.
Take GLDPM as an opportunity - reusing the required data has the potential to increase the supply security of your medium and low voltage networks!
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 DSO 2.0 which provides you with a modular, expandable, and therefore future-proof solution.
The energy transition results in higher utilization of the distribution networks. Continuous supply of energy is not possible with decentralized weather-dependent generation. Equal demand for the generated energy at all times of the day remains unlikely today as well as in the future.
Capacity calculation based on a standardized procedure for the electricity traded on the day-ahead and intra-day markets requires data exchange across networks. Under today's aspects, a transparent Europe-wide overview is absolutely necessary.
Since the beginning of 2018, the European transparency regulation requires all energy generators and plant operators to share their load and generation data with the upstream transmission network operators and to provide the corresponding equivalent network models.
Based on the new requirements for the distribution system operators imposed by GLDPM, PSI has examined other energy network developments in detail.
With the expansion of renewable energies, the application "Security Assessment & System Optimization" (SASO) which was initially designed for transmission system operators now also provides substantial benefits to distribution system operators.
DSO-specific features have been integrated in the SASO module which now provides you with an optimal basis for using the GLDPM data to ensure the stability of your high and medium voltage networks.
Seamless handling of various file formats
Basis for additional/future network security applications
The separate PCOM+ module is used for exchange and archiving of time series. The extendable communication center operates as bi-directional communication interface to other systems. PCOM+ 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.
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 se-curity 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.
