Abstract:

A dual decomposition approach for the distributed control of both reactive power and storage control in microgrids is presented. This approach considers physical constraints inherent to storage systems, as well as voltage regulation constraints. The objective is to minimize a cost function consisting on a linear combination of the overall active power cost over a finite time horizon, and the transmission losses over the microgrid. A distributed algorithm is introduced for which we present the corresponding convergence result. In addition, we introduce a novel approximate distributed voltage prediction algorithm that can be used to make the approach fully distributed. Simulations demonstrate the dual decomposition algorithm performance on a particular microgrid case.
