Phase Lock Loop-Related Improvements to Non-Synchronous Generation Models

The intention of this project is to bring about revolutionary change to our non-synchronous models by introducing PLL-informed non-synchronous dynamic performance models into our power system analysis tool digsilent. We can validate the models against real experience so as to be as accurate as possible. This validation process is in itself innovative given there is no precedent or process for doing this today, here or internationally. The intended internal outputs from this exercise would be both a step change in our modelling capability of non-synchronous technology and a pathway to sustain this step change into normal business. The intended external outputs from this project would be to provide the wider industry with reference modelling insight for different types of PLL informed control, and also provide a recommended process which allows these reference models to be validated, adapted or allocated based on the Users own technology choices and connection context.

Objectives

The intended objectives from this exercise would be

Develop a step change in our modelling capability of non-synchronous technology in the context of future network conditions across which more detailed modelling now becomes more important, developing the new processes and techniques to assure the validity of these models, and developing a pathway to sustain this step change into normal business.
To provide the wider industry with reference modelling insight for different types of PLL informed control, and also provide a recommended process which allows these reference models to be validated, adapted or allocated based on the User’s own technology choices and connection context.
