A Flexible Mixed-Integer Linear Programming Approach to the AC Optimal Power Flow in Distribution Systems
TL;DR: In this article, a flexible mixed-integer linear programming formulation of the AC OPF problem for distribution systems, using convexification and linearization techniques, is proposed, which allows the representation of discrete decisions via integer decision variables, captures the nonlinear behavior of the electrical network via approximations of controllable accuracy, and can be solved with commercial optimization solvers.

Computer-Aided Planning of Distribution Substation and Primary Feeders
Abstract: This paper presents an improved technique for optimal planning of substations and primary feeders in power distribution systems. The technique employs an accurate, time-phased cost model and incorporates a flexible planning formulation which suits detailed analysis of limited sized distribution networks as well as approximate analysis of large scale distribution networks. The cost model includes explicit time-dependent fixed and variable charges for planned facilities as well as the cost of power losses. The planning formulation incorporates user-defined constraints on voltage drop in primary feeders. Constraints on radial power flow are automatically set by the algorithm. The planning problem is solved using an advanced, sparsity-based mixed-integer linear programming code.
