Estimation of Disturbance Size and Frequency Nadir Prediction in RE Integrated Power Systems
Subcategory (under Clean Energy): Cross Cutting
Technology Readiness Level (TRL): TRL 4 - Early prototype
Technology Outline (Process Description)
Background and Motivation:
Variable, intermittent, and non-synchronous nature of RES-based power generation introduces several technical challenges.
Reduced level of inertia and its heterogeneous distribution, together with time-varying inertia profiles, impacts frequency stability.
Estimating disturbance size immediately after the contingency is essential to accurately predict frequency nadir and maintain system reliability.
A method is developed for online estimation of disturbance size for Renewable Energy-dominated power systems. The estimated disturbance size is used to predict the frequency nadir immediately after the disturbance.
Applications:
Help power system operators take preventive/corrective actions after credible contingencies.
Improves the power system control, operation, and reliability.
Salient Features/Advantages
