Grid Studies
PSSE Studies
Grid interconnection and transmission planning studies in PSS®E, demonstrating that new generation and loads connect safely and meet grid code requirements.
Key PSS®E studies
- Steady-state load flow and contingency
- Short circuit studies
- Dynamic and transient stability
- Grid code compliance for IPPs
Overview
Grid studies for interconnection and planning
Connecting a power plant, solar or wind farm or large industrial load to the transmission grid requires studies that prove the connection will not compromise system security. Utilities and system operators widely use PSS®E for this work.
DCPS prepares grid impact and interconnection studies in PSS®E, including load flow under normal and N-1 contingency conditions, short circuit analysis and dynamic simulations of faults and disturbances. For renewable plants we model inverters and plant controllers and assess reactive power capability, voltage control and fault ride-through against grid code requirements.
Our reports are structured for submission to transmission and distribution companies and support you through their review.

Who needs PSS®E studies
FAQ
Frequently Asked Questions
Why are PSS®E studies required for a new plant?
Utilities need evidence that the plant will not cause overloads, voltage problems or instability and that it meets grid code requirements before approving the connection.
Do you need the utility base case?
Yes. The study is performed on the latest network base case provided by the transmission or distribution company.
Can you model solar and wind plants?
Yes. We model inverter-based plants with appropriate generic or manufacturer dynamic models and plant controllers.
Do you respond to utility comments?
Yes. We revise the study and provide clarifications until the review process is complete.
