Expanding out the generator block yields the simPower model shown on the right. Main blocks of interest include the central block, which contains the UWM controller logic, and the lower block for the event trigger. This event-triggering block realized the decision logic discussed in the preceding chapter. It was implemented as an S-function block.
The UWM control logic was realized as a Matlab Simulink model shown to the left. It is similar to the simulink model developed by UIUC under phase I of this project with some minor modifications that were needed to support the event-triggered dispatching system. While this simulation worked well in demonstrating the effectiveness of the event-triggered dispatch algorithm, it was insufficient for the needs of this project. The preceding models lacked sufficient modularity to enable the straightforward integration of different generation sources. A more flexible and accurate simulation model for the UWM testbed will be described in chapter 4.
