Control strategies of active power filters for harmonic voltage mitigation in multibus industrial power systems

“…It results, effectively, to the suppression of harmonic voltages too. Now, the feedback is specified by (3) where G is the feedback gain matrix and I is the branch current vector. The solution of the single APF -single harmonic problem presented in [1] provides us with the set of optimal compensator currents for individual harmonic orders.…”

“…The problem of an optimal location of active power filters as well as of current spectra injected by them and demanded for minimum harmonic voltage distortion has been formulated either as unconstrained or constrain optimization problem solved by analytical procedures [1], graphic methods [2] or by using some techniques suitable for very large scale optimization problems [3]. A strategy enabling us to exactly determine the most effective points of connections of active power filters in multibus power systems with distributed harmonic sources bas been presented in [4].…”

Optimal Sizing of Harmonic Filters in Electrical Systems: Application of a Double Simulated Annealing Process

“…Corresponding to the harmonic currents either drawn by a passive filter or injected by an active filter, the filtering currents are calculated not to cancel the resulting harmonic voltages as proposed in [9], but to bring their magnitude within the limits recommended by the standards [10]. The optimisation of the filter size is then applied separately for each harmonic order by means of a double SA process ruled by two distinctive objective functions and the results are known in terms of filtering power to install with the resultant harmonic voltages expected on the distribution network.…”

Connection of Shunt Active Power Filters in Multibus Industrial Power Systems for Harmonic Voltage Mitigation

“…Active power filters have been analyzed mainly in terms of operation principles, control algorithms, and performance characteristics [1]. Some analyses have been related with active filter compensation performance in power distribution systems [2]- [4], [5]. The performance and effectiveness of the active power filter depends on the point of its connection.…”
