Network Stress Test (NST) Siemens PSS SINCAL Massive and Parallelized Analysis Modules

Network Stress Test (NST) Requirements and Use Cases

The integration of the charge infrastructure for electromobility or decentral energy resources (DER) leads impacts mainly the distribution networks.

Since these loads or feed-ins vary both in terms of location and time, the planning cannot work with predefined locations and times for the expansion of the charging infrastructure (and comparable elements to be modeled, such as heat pumps) or decentral energy resources (DER). A stochastic approach is required for a random distribution of the planned consumers or power generation systems in the supply area and the subsequent calculation and network analysis.

• Checking of the utilization (loading) of equipment due to the additional charging infrastructure/decentral energy resources (DER)
• Checking of the permissible deviations of the network voltage due to the additional charging infrastructure/ decentralized power generation systems (DER)
• Provision or inclusion of the required power by the local substation
• Determination of the critical penetration of the supply area in a medium to long-term planning period
• Identification of weak points in the network for planning the network expansion or reinforcement

Solution

The module for performing a network stress test (NST) in PSS®SINCAL allows you to analyze the effects of increasing integration of loads and decentral energy resources (DER) in the supply area.

• Analysis of the absorption capacity of supply areas for load elements/decentral energy resources (DER) in a probabilistic bottom-up approach by random distribution of the elements
• Classification of possible connection points and the loads/DC infeeders to be connected by means of types
• Calculation of a user-defined number of loops and thus a random configuration in each loop
• Variation (increase) in network penetration over the analyzed period
• Interactive evaluation and documentation of critical configurations in relation to limit values for voltage and utilization (loading)
