TL;DR: Electromagnetic transients in arbitrary single- or multiphase networks are solved by a nodal admittance matrix method based on the method of characteristics for distributed parameters and the trapezoidal rule of integration for lumped parameters.

TL;DR: A practical method is given for solving the power flow problem with control variables such as real and reactive power and transformer ratios automatically adjusted to minimize instantaneous costs or losses by Newton's method, a gradient adjustment algorithm for obtaining the minimum and penalty functions to account for dependent constraints.

TL;DR: A new technique for solving the differential equations with the implicit trapezoidal rule of integration can be combined into one simultaneous solution, thereby eliminating the problem of interface error between the differential and algebraic equation solutions of the traditional approach.

TL;DR: In this paper, a computer-based multiphase harmonic load flow solution technique for analyzing unbalanced load conditions in power systems is described. Butts et al. used static VAr compensators with thyristor-controlled reactors under unbalanced loads to illustrate the method.

TL;DR: The possibility of leveraging the data provided by smart meters to understand the load characteristics is studied and a deterministic framework is proposed that formulates the VVO problem as a mixed-integer quadratically constrained programming problem, which is solved efficiently using advanced branch-and-cut techniques.
