Design of Self-adaptive Single Neuron Facts Controllers Based on Genetic Algorithm

Quan-Yuan Jiang, Chuang-Xin Guo, Yi-Jia Cao

Lecture Notes in Computer Science > Advances in Neural Networks - ISNN 2006 > Power Systems > 1332-1337

With the growing application of Static Var Compensator (SVC) and Static Synchronous Compensator (STATCOM), the coordinating problem of SVC and STATCOM controllers in joint operation must be considered in modern power systems. This paper firstly establishes the nonlinear differential-algebra equations model of a single-machine infinite-bus (SMIB) power system installed with a SVC and a STATCOM and...

Generation maintenance scheduling based on multiple objectives and their relationship analysis

Jun-peng Zhan, Chuang-xin Guo, Qing-hua Wu, Lu-liang Zhang, more

Frontiers of Information Technology & Electronic Engineering > 2014 > 15 > 11 > 1035-1047

In a market environment of power systems, each producer pursues its maximal profit while the independent system operator is in charge of the system reliability and the minimization of the total generation cost when generating the generation maintenance scheduling (GMS). Thus, the GMS is inherently a multi-objective optimization problem as its objectives usually conflict with each other. This paper...

Mixed nonlinear dynamic voltage phasor tracing method based on WAMS/SCADA

Xiao-gang Chen, Yong-hui Yi, Wei Wang, Quan-yuan Jiang, more

Journal of Zhejiang University-SCIENCE A > 2009 > 10 > 6 > 868-876

By considering the static voltage characteristic of the load, we propose a WAMS/SCADA mixed nonlinear method to estimate the voltage of unobservable buses caused by topology change or phasor measurement unit (PMU) malfunction in a power system. By modeling the load characteristic with data from SCADA, we employed the Gauss-Seidel method to solve the nonlinear equations and estimate the voltage of...

Forward and backward models for fault diagnosis based on parallel genetic algorithms

Yi Liu, Ying Li, Yi-jia Cao, Chuang-xin Guo

Journal of Zhejiang University-SCIENCE A > 2008 > 9 > 10 > 1420-1425

In this paper, a mathematical model consisting of forward and backward models is built on parallel genetic algorithms (PGAs) for fault diagnosis in a transmission power system. A new method to reduce the scale of fault sections is developed in the forward model and the message passing interface (MPI) approach is chosen to parallel the genetic algorithms by global single-population master-slave method...

A pooled-neighbor swarm intelligence approach to optimal reactive power dispatch

Chuang-xin Guo, Bo Zhao

Journal of Zhejiang University-SCIENCE A > 2006 > 7 > 4 > 615-622

This paper presents a pooled-neighbor swarm intelligence approach (PNSIA) to optimal reactive power dispatch and voltage control of power systems. The proposed approach uses more particles℉ information to control the mutation operation. The proposed PNSIA algorithm is also extended to handle mixed variables, such as transformer taps and reactive power source installation, using a simple scheme. PNSIA...

Swarm intelligence for mixed-variable design optimization

Chuang-xin Guo, Jia-sheng Hu, Bin Ye, Yi-jia Cao

Journal of Zhejiang University-SCIENCE A > 2004 > 5 > 7 > 851-860

Many engineering optimization problems frequently encounter continuous variables and discrete variables which adds considerably to the solution complexity. Very few of the existing methods can yield a globally optimal solution when the objective functions are non-convex and non-differentiable. This paper presents a hybrid swarm intelligence approach (HSIA) for solving these nonlinear optimization...
