Dynamic Model Acceptance Test

Posted on by Ngoc Khanh

Vietnam Power Resource Partners Corporation (PRP) offers a robust Dynamic Model Acceptance Test (DMAT) service designed to validate the performance of renewable energy systems, such as solar, wind, and battery energy storage systems (BESS), within modern power grids. Integrating these renewable energy sources is crucial for ensuring grid reliability and efficiency. Our DMAT service is a comprehensive solution that covers every aspect of model validation, ensuring that these energy systems operate within the required standards and perform reliably under various grid conditions.

Service Highlights

  1. Model Setup and Preparation:

    • Documentation Review: We begin by gathering and thoroughly reviewing technical documents, including transfer function block diagrams, parameter lists, and model validation reports from the original equipment manufacturers (OEMs). This step ensures that the models are set up accurately, reflecting the real-world characteristics of renewable energy systems.
    • Model Configuration: Using advanced simulation tools such as PSS®E and PSCAD, our team develops and configures models specific to solar, wind, and BESS plants. We adjust impedance settings to match the fault levels at the Point of Connection (PoC), which is critical for accurate fault simulations.

  2. Extensive Testing Procedures:

    • Initialization and Stability Tests: Our initial tests ensure that the models initialize correctly and remain stable across various conditions, including different Short Circuit Ratio (SCR) and X/R ratios. Stability is crucial for maintaining grid reliability.
    • Balanced and Unbalanced Fault Tests: We simulate three-phase ground faults as well as single and two-phase faults with varying impedances and durations. These tests are designed to assess the model’s response to large disturbances and its ability to maintain stability during unbalanced conditions.
    • Multiple Fault Ride Through (MFRT): In this critical test, we generate sequences of random faults to evaluate the model’s capability to ride through multiple disturbances without losing stability. This test is essential for ensuring that renewable energy systems can handle real-world scenarios where multiple faults might occur in rapid succession.
    • Control System Reference Step Changes: We apply step changes to various control references, including voltage, reactive power, and active power, to validate the model’s performance under different grid strengths. This includes specific tests for power factor control and grid frequency control, which are vital for maintaining the overall stability of the power system.
    • Grid Oscillation and Phase Angle Tests: We simulate oscillatory disturbances and phase angle changes in the grid voltage to assess the model’s ability to reject oscillations and maintain stability during phase shifts. These tests ensure that the system can handle dynamic grid conditions without compromising performance.

  3. Comprehensive Data Analysis and Reporting:

    • Simulation Analysis: We analyze the results from each test, comparing the observed behaviour against the expected outcomes as defined by the Network Operator’s guidelines. This analysis helps identify any potential issues or areas where the model might need further refinement.
    • Detailed Documentation: For each test case, we prepare detailed reports that document the methodology, results, and any observations. These reports include recommendations for addressing any issues and highlight areas for potential improvement. We also prepare user guides for the simulation software, ensuring that the Network Operator and other stakeholders have a clear understanding of the model configurations and test procedures.

  4. Project Timeline and Management:

    • Structured Timeline: The DMAT process follows a clearly defined timeline that includes phases for model setup, testing, data analysis, and final reporting. Each phase is carefully managed to ensure timely completion, with dedicated time allocated for addressing any feedback from the Network Operator.
