Power Grid Modeling Validation and Calibration

Power system modeling is a difficult task for engineers trying to build computer models to closely simulate the actual, physical power grid. Yet, power system models are the key to accurate power grid monitoring and analysis. If certain aspects of the model are inaccurate, this will be further reflected in the analysis.

BSI has a suite of modeling tools to identify errors in power system models and the ability to calibrate and fine tune the parameters.

Generator Parameter Model Validation and Calibration

This software tool will detect generator and power plant model inadequacies and calibrate its parameters on-line to improve accuracy using PMU and/or SCADA measurement data.

Model inadequacy detection will verify the adequacy of the current model in describing system dynamic behaviors. The engine will simulate model outputs and compare the model outputs with the field measurements.

Model parameter calibration takes places after errors are identified. This procedure involves the tuning of model parameters so that the model’s simulation outputs match the measured system responses.

Transmission Parameter Model Validation and Calibration

NERC Mod 033-01 Steady-State and Dynamic System Model Validation standard requirements and compliance procedures showcase the importance and need for accurate models and parameter data. This can be achieved by performing model validation and calibration studies.

The WECC (Western Electricity Coordination Council) Task Force stated the following recommendations for all member utilities:

  • “The Industry should make periodic model validation and benchmarking an integral part of off-line study model maintenance.”
  • “The Industry should validate operational planning (offline) models by comparing them with models developed from real-time data...”

The BSI Parameter Error Identification and Correction (PEIC) tool is used to detect model inadequacy and improve model accuracy for power transmission systems using on-line measurement data. First, the tool will identify suspicious parameters that are found throughout multiple measurement scans and then calibrate to ultimately correct these parameters.

Parameters include:

  • r, x, and bch of transmission lines
  • r, x, and tk of power transformers
  • x of shunt capacity

Input data needed include SCADA data and/or PMU measurement data and network topology. Other measurement devices can also be used.

Load Modeling

Intelligent Dynamic Engineering Advisor for Load Modeling (IDEAL)

  • Software platform for estimating load model parameters from field measurements
  • Measurements collected from disturbance recorders or synchronized phasor measurement (PMU) units
  • Select the load model from the pool of 18 different composite load models
