The problem of voltage regulation is addressed in power distribution networks with deep-penetration of distributed energy resources, e.g., renewable-based generation, and storage-capable loads such as plug-in hybrid electric vehicles. The problem is cast as an optimization program, where the objective is to minimize the losses in the network subject to constraints on bus voltage magnitudes, limits on active and reactive power injections, transmission line thermal limits and losses. Sufficient conditions are provided, under which the optimization problem can be solved via its convex relaxation. Data from existing networks show that these sufficient conditions are expected to be satisfied by most networks. An efficient distributed algorithm is provided to solve the problem. The algorithm adheres to a communication topology described by a graph that is the same as the graph describes the electrical network topology.
