Abstract :
This paper presents an on-line centralized controller based on Model Predictive Control concepts to regulate distribution network voltages, and possibly support transmission network. It computes and applies a sequence of changes of the distributed generators power outputs to progressively meet a set of operation constraints at distribution, and possibly transmission level. An 11-kV, 75-bus test system with 22 distributed generators is used to illustrate the performance of the proposed controller when transmission system support is requested. Comparisons with single-step open-loop control are also provided.
