| Abstract: |
| Dynamic behaviour of frequency is crucial for power system operation and control. Several frequency response
models have been proposed to reveal frequency dynamics from different aspects. A comprehensive software
package incorporating major frequency response models is needed for analysis and control of power system
frequency dynamics. In this paper, an approach for developing a programmable and open software package for
frequency response studies is proposed. The framework of the package is extendable with reduced frequency
response models. Essential models for frequency response study are included, e.g., generator, load, and
under-frequency load shedding (UFLS). The provided application program interfaces (APIs) enable simulation
with high-level languages by calling dynamic link library and makes the package programmable. An advanced
application module is developed for quantitative assessment of transient frequency deviation. APIs can also
be used for model extension and secondary development. To demonstrate the usage of the package, several
examples are illustrated to explain how to perform simulations with the package, and to perform advanced
applications using scripting with the provided APIs. |
