Parallel solution of Newton's power flow equations on configurable chips
TL;DR: A novel partitioning scheme for the nonsymmetric Jacobian matrices appearing in the Newtons’s method results in the efficient parallelization of LU factorization and the subsequent solution of the power flow equations.

Multi-objective mean–variance–skewness model for nonconvex and stochastic optimal power flow considering wind power and load uncertainties
TL;DR: A reliable model to assess the NSOPF from the perspective of economics and reliability of power system operation is developed, and an efficient algorithm to obtain a solution that considers all of the possible load and wind power simultaneously is proposed.
