Grid Code Compliance Renewables (EEG) Siemens PSS SINCAL Massive and Parallelized Analysis Modules

Grid Code Compliance Renewables (EEG)

Requirements and Use Cases

The integration of decentral energy resources (e.g. photovoltaic systems, wind turbines, combined heat and power plants) into distribution networks is particularly occurring on medium and low voltage network levels. In the planning phase, many countries require that the connection conditions of these systems must be verified during the design phase based on procedures and criteria defined in national standards and guidelines. The large number of (often parallel) requests to a network operator requires their careful but rapid processing and documentation.

• Implementation of a standardized procedure for checking specified limit values for the deviations of voltage, short-circuit behavior and the emission of harmonic voltages (connection assessment)
• Automatic processing of the assessment in order to process a large number of requests in a short time
• Documentation and securing of the results of the connection check for technical and legal discussions

Solution

The verifying of the connection conditions as a module (EEG) in PSS?SINCAL offers a separate screen form for the individual steps of a connection check by the network operator. The user is guided step-by-step through the data input of the DER system, the selection of the process and analysis area and the definition of the respective limit values as well as the execution of the calculation and evaluation of the results.

• Integration of the individual work steps in an efficient, specified workflow with its own screen form without additional modeling effort in the network model
• Summary of the calculations required for the check (load flow, short circuit and optional harmonics)
• Default values according to the limit values of the standards and guidelines as well as option for adjustment of the values by the user
• Automatic evaluation of the calculation results against the limit values and documentation
