In this paper optimal control strategies for active power filters working under non-sinusoidal voltage are approached using Pareto Optimal based multi-objective optimization. Where the voltages are distorted, there is some conflict between power factor improvement, current harmonics mitigation, and cost issues. The Strength Pareto multi objective optimization approach is used to simultaneously optimize...
Power system stabilizers (PSSs) are the most well-known and effective tools to damp power system oscillation caused by disturbances. To gain a good transient response, the design methodology of the PSS is quite important. The present paper, discusses a new method for PSS design using the multi-objective optimization approach named Strength Pareto approach. Maximizations of the damping factor and the...
The most common way of multi-objective optimizations is assigning a weight to each objective and construct a single fitness function. In this method finding of the appropriate weights is the most important problem. The second method, which is not very well-known for power system researchers, is to optimize the objectives independently. Many optimum answers are achieved instead of a single one. These...
This paper introduces the theory and application of a new designing method of the controller for boost single-phase ac-dc converters with power factor correction. The method is based on the use of a Multi-Objective optimization evolutionary algorithm which is called NSGA-II. As the input current quality and dynamic response of output voltage for PFC rectifiers are conflicting objectives and with improving...
Power quality filters (PQF) are the most effective tools to reduce power system harmonics. Passive harmonic filter (PHF) is the simplest and cheapest kind of PQFs. Designing and tuning of PHF is a crucial issue for many power system researchers. The filter should overcome the harmonics generated in the voltage and current waveforms due to the nonlinear characteristics of the power system, distorting...
