ALPS — AGORA Loadflow for Power Systems (TM) Analysis Tools

AGORA Loadflow Algorithm (Patent Pending) This Deterministic power flow calculation method will always provide the correct physical solution to the power flow equations. It will never provide an incorrect solution, and will never fail to find the solution when one exists. This single power flow method will always work, even under voltage collapse conditions - you don’t have to choose a starting point or find the optimum method through trial and error. The software will also provide useful information on constraining parameters when there is no solution (i.e, the system is at voltage collapse).

Achieve Accurate Power Flow Results Under any System Condition, Improve Engineering Productivity, and Ensure System Reliability With ALPS.

Graphical Editing and Debug Tools Import base cases from other power flow software formats. Bus-level and system-level one-line diagrams are automatically created from the imported model. Create and edit models with graphical drawing and editing tools. Software tools are provided to assist in the identification of model topology errors and parameter inconsistencies.	Model Editing tool
Graphical Solutions Analysis ALPS provides a powerful set of graphic displays to review the case input data and the power flow solution. PV and QV Curve Generation ALPS automatically draws PV or QV curves for any specified bus, showing the exact point of voltage collapse.	Model Debugging Tools
Contingency Analysis Analyze base case under various user-defined lists of contingencies. The results identify all voltage and thermal limits that are exceeded, and the software will optionally determine the optimum actions to eliminate the limit violations (RLV Module).
Power Flow Results
Who should use ALPS? Everyone who performs power flow studies needs accurate results, no starting solution, and no convergence problems. This software is designed for anyone who develops offline analysis. It is very useful for operations engineers and planning engineers.
How fast is ALPS’s power flow calculation? Computationally, ALPS is comparable in speed to Newton-Raphson based algorithms. However, because of its accuracy and robustness, you can virtually eliminate the “trial and error” techniques commonly used to achieve convergence with Newton-Raphson tools, letting you achieve unsurpassed productivity for power flow calculations.
System Requirements AGORA off-line power system analysis tools will run on any operating system that is compliant with Java 2 runtime environment 1.4.2.  For use with large system models, we recommend fast CPUs and maximum RAM. Substantial disk space or disk arrays should be provided to store large base cases or large quantities of small base cases.
