Query: A distributed control strategy for reactive power compensation in smart
  microgrids   We consider the problem of optimal reactive power compensation for the
minimization of power distribution losses in a smart microgrid. We first
propose an approximate model for the power distribution network, which allows
us to cast the problem into the class of convex quadratic, linearly
constrained, optimization problems. We then consider the specific problem of
commanding the microgenerators connected to the microgrid, in order to achieve
the optimal injection of reactive power. For this task, we design a randomized,
gossip-like optimization algorithm. We show how a distributed approach is
possible, where microgenerators need to have only a partial knowledge of the
problem parameters and of the state, and can perform only local measurements.
For the proposed algorithm, we provide conditions for convergence together with
an analytic characterization of the convergence speed. The analysis shows that,
in radial networks, the best performance can be achieved when we command
cooperation among units that are neighbors in the electric topology. Numerical
simulations are included to validate the proposed model and to confirm the
analytic results about the performance of the proposed algorithm.
