Quasi-Newton Methods for Power Flow Calculation

2020 International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE), 2020
In this work, we compared the performance of the ordinary Newton-Raphson method for calculating power flows against three quasi-Newton methods: chord, “good” and “bad” Broyden's methods.

Quasi- Newton Methods for Nonlinear Equations

Journal of the ACM, 1968
A unified derivation is presented of the quasi-Newton methods for solving systems of nonlinear equations. The general algorithm contains, as special cases, all of the previously proposed quasi-Newton methods.

Cancellation Errors in Quasi-Newton Methods

SIAM Journal on Scientific and Statistical Computing, 1986
Using a probabilistic estimate, the author gives the effect of cancellation on the performance of quasi-Newton methods. First, the author describes and shows that the size of the low rank correction can be measured for the BFGS method. This BFGS method is used to find a local solution \(x^*\) of the problem: minimize f(x), \(x\in {\mathbb{R}}^ n ...

Optimization of Simulation via Quasi-Newton Methods

ORSA Journal on Computing, 1994
This paper discusses the application of quasi-Newton methods to optimization of simulation. Specifically, it describes a general methodology that combines response surface methodology and other optimization techniques with quasi-Newton methods. Using quasi-Newton methods in the vicinity of the optimum speeds up the convergence rate of response surface

Maximum Entropy Derivation of Quasi-Newton Methods

SIAM Journal on Optimization, 2016
Summary: This paper presents a maximum-entropy (MaxEnt) derivation of many commonly used quasi-Newton rules. (i) This derivation interprets the elements of the Jacobian or Hessian as means of a multivariate probability distribution; (ii) the variance is chosen to represent the uncertainty about the mean.

Quasi Newton methods and unconstrained optimal control problems

1986 25th IEEE Conference on Decision and Control, 1986
The authors consider the problem min F(x) on a Hilbert space H. The necessary condition \(\nabla F(x)=0\) is approximated by a sequence of finite dimensional equations \(G_ N(x)=0\), \(x\in H_ N\), which could be solved by the quasi-Newton procedure proposed by Broyden, Fletcher, Goldfarb and Shanno (BFG) [see \textit{C. G.

Quasi-Newton methods for saddlepoints

Journal of Optimization Theory and Applications, 1985
The well-known quadratically convergent methods of the Huang type [cf. \textit{H. Y. Huang}, ibid. 5, 405-423 (1970; Zbl 0184.202) and \textit{H. Y. Huang} and \textit{A. V. Levy}, ibid. 6, 269-282 (1970; Zbl 0187.404)] to maximize or minimize a function \(f: {\mathbb{R}}^ n\to {\mathbb{R}}\) are generalized to find saddlepoints of f.
