Area Tie Report
PSS®MUST is a tool for managing and utilizing system transmission. The tool supports engineers in determining transmission transfer capability by simulating network conditions with equipment outages during changing network conditions.
PSS®MUST complements PSS®E data handling and analysis functions with the most advanced linear power flow and user interface available. PSS®MUST speed, ease-of-use, and versatile EXCEL interface simplifies and reduces data setup time, and improves results display and understanding.

The tool efficiently calculates:
Transaction impacts on transmission areas, interfaces, monitored elements or flowgates
Generation redispatch factors for relieving overloads
Incremental transmission capability (FCITC)
FCITC variations with respect to network changes, transactions, and generation dispatch
The impact of transmission element outages on power flow by both DC and AC contingency analysis
Automated calculation of Available Transfer Capacity (ATC) and Available Flowgate Capacity (AFC) values
Users benefit from:
Users only need to set up the study once for various applications
Rapid assessments provide for fast response to constantly changing network conditions and consequential impacts
Network problems can be anticipated and alternatives can be analyzed with speed and ease
Specialized engine provides extremely fast transfer analysis, both linear and non-linear study methods
Calculates the area exchanges in the planning network model.
PSS®MUST includes a full Python™ Application Program Interface (API), allow fast and powerful integration of automated PSS®MUST workflow with PSS®E and other 3rd party tools, such as Microsoft Office.
The latest release introduces an advanced SCED functionality for calculation of preventive and corrective cases when considering a very large set of n-1 or n-1-1 contingencies.
It enhances three main features:
Dispatch: It minimizes the required generation dispatching or load shedding to remove overloads
Control: It reduces the response time and simplifies contingency control in real-time
Speed: Advanced speeds are achieved to determine a preventative case in even large cases. In one case, the calculation precisely determined a preventive case in only 24 seconds for an 81614-bus system with 2027 contingencies while correcting 71 cases with overloads.
"Coming soon" with the integration into PSS®E as the “MUST add-on module”, users can immediately experience the following benefits:
Seamless interaction – Directly invoke MUST functionality from the PSS®E GUI and make use of the network case in PSS®E memory while continuing to view results in Excel spreadsheets.
Enhanced automation – Ability to develop and run a single script that uses both the PSS®E modules (such as psspy and pssarrays) as well as the MUST module (mustpy).
Increased performance – PSS®E v35.0, including the MUST add-on module, will support x64 bit so you can handle even larger cases.
