Transient stability constrained optimal power flow applied to large power systems
FY 2011-12
Summary
The power systems nowadays are operating closer to their stability limits. As a result, the stability phenomena such as angular and voltage stability have become more and more serious issues. Traditionally, the production planning tasks such as Optimal Power Flow calculations (OPF) are decoupled from the stability analysis. However, due to the growing concern about system stability, the combination of these two tasks in the production planning process has been observed recently. In this new framework, not only the OPF problem has to tackle static constraints such as power balance and voltage/reactive power limits, the optimization procedure also has to ensure that the optimal operating point remains stable following some typical system contingencies.
In this project, the OPF framework which takes into account transient stability constraints is developed. To ensure the accuracy of stability evaluation, the transient stability condition is evaluated, based on detailed time domain simulations. The framework will be tested on a real large scale power system model, in which all elements having considerable impact on the transient stability, such as the generator excitation system and damping controllers will be modeled. The main challenge for this approach is to provide an efficient analysis tool, which has a sufficient modeling accuracy, and does not require too much calculation time. Therefore, the main objectives of the project are to develop fast and accurate algorithm for the determination of power system transient stability, and to provide the best compromise between modeling accuracy and calculation speed. The project is divided into the following main research themes: Building test system models and carry out contingency analysis and ranking; development of fast and accurate algorithm for transient stability evaluation based on time domain simulation; development of generator and network aggregation methods to reduce the computation burden. Finally, the TSC-OPF will be established by combining a conventional OPF with the transient stability constraints constructed in the previous themes.
