TLDR
The details of the network modeling and problem formulations used by MATPOWER, including its extensible OPF architecture, are presented, which are used internally to implement several extensions to the standard OPF problem, including piece-wise linear cost functions, dispatchable loads, generator capability curves, and branch angle difference limits.
Abstract
MATPOWER is an open-source Matlab-based power system simulation package that provides a high-level set of power flow, optimal power flow (OPF), and other tools targeted toward researchers, educators, and students. The OPF architecture is designed to be extensible, making it easy to add user-defined variables, costs, and constraints to the standard OPF problem. This paper presents the details of the network modeling and problem formulations used by MATPOWER, including its extensible OPF architecture. This structure is used internally to implement several extensions to the standard OPF problem, including piece-wise linear cost functions, dispatchable loads, generator capability curves, and branch angle difference limits. Simulation results are presented for a number of test cases comparing the performance of several available OPF solvers and demonstrating MATPOWER's ability to solve large-scale AC and DC OPF problems.

Voltage Stability in a Grid-Connected Inverter With Automatic Volt-Watt and Volt-VAR Functions

TL;DR: A rigorous stability analysis of a grid-connected inverter under simultaneous operation of automatic Volt-Watt and Volt-VAR response functions reveals a little-known stability vulnerability arising if Watt output takes precedence over the provision of VAR support, a generally recommended setting.

Distributed Optimal Voltage Control With Asynchronous and Delayed Communication

TL;DR: In this paper, the authors proposed a distributed feedback control algorithm where each bus can inject both active and reactive power into the grid to regulate the voltages, and they proved that the algorithm converges to the optimal feasible voltage profile, assuming linear power flows.
