Describe and simulate more accurately the physical behavior of the grid and connected equipment under stable operating conditions, identify potential vulnerabilities, and help ensure reliable operation with Steady State Power Flow (formerly PSLF).
Advanced power flow solutions and contingency power system analysis
Plan for the future expansion of your power systems and help ensure that your existing network operates reliably under normal conditions with the PlanOS* Steady State Power Flow module. Improve your operations by determining the most suitable control and planning actions to help identify issues such as overloaded equipment and voltage instability before they become problematic. With Steady State Power Flow, your team can more easily assess the impact of changes in generation, demand, network topology, and faults in the power system—all from a single module.
- Create N–1, N–1–1, and N–2 contingencies.
- Easily generate control and case files.
- Execute transmission planning, interconnection analysis, and contingency analysis.
- Build custom contingencies for specialized use cases.
Power system engineering analyses
- Contingency analysis
- Transfer analysis
Steady state contingency analysis is a vital process in power systems engineering that evaluates the impact of potential failures or unexpected events on the power grid. By simulating various "what-if" scenarios, such as the sudden loss of a transmission line or generation unit, this analysis helps ensure the stability and reliability of the power system under different conditions. Contingency analysis is natively integrated with the Steady State Power Flow module of PlanOS.
- Uninterrupted power supply: Helps utility companies and grid operators maintain consistent power delivery.
- Mitigates potential disruptions: Enables operators to foresee and address the effects of potential disturbances.
- Optimizes resource allocation: Provides insights into how different network components react under stress, guiding investment in critical infrastructure.
- Regulatory compliance: Assists utilities in demonstrating system reliability and stability as required by regulatory bodies.
Steady state transfer capability analysis is a crucial process in power systems engineering that evaluates the maximum amount of electrical power that can be transferred over the transmission network from one area to another without violating system limits under steady state conditions. By assessing the transfer limits, this analysis ensures the safe and reliable operation of the power grid.
- Enables Grid Reliability: Identifies transfer limits to prevent overloads and maintain system stability.
- Optimizes Power Flow: Helps manage power distribution efficiently, reducing congestion and enhancing system performance.
- Supports Market Operations: Provides crucial data for energy trading, enabling market participants to maximize transactions while ensuring system security.
- Facilitates Infrastructure Planning: Informs investment decisions in transmission infrastructure, helping meet future demand and improve grid resilience.
