TL;DR: In this article, the authors consider the problem of deriving an explicit approximate solution of the nonlinear power equations that describe a balanced power distribution network and propose an approximation that is linear in the active and reactive power demands of the PQ buses.

TL;DR: An approximate model for the power distribution network is proposed, which allows the problem of optimal reactive power compensation for the minimization of power distribution losses in a smart microgrid to be cast into the class of convex quadratic, linearly constrained, optimization problems.

TL;DR: Convergence to the configuration of minimum losses and feasible voltages is proved analytically for both a synchronous and an asynchronous version of the algorithm, where agents update their state independently one from the other.

TL;DR: This paper considers a linear network-reduced power system model along with an $\mathscr {H}_2$ performance metric accounting for the network coherency and provides a set of closed-form global optimality results for particular problem instances as a computational approach resulting in locally optimal solutions.
