Simultaneous allocation of capacitors and voltage regulators at distribution networks using Genetic Algorithms and Optimal Power Flow
چکیده انگلیسی

The high reactive power level demanded by the distribution systems, the loads growth and consequent increase of system losses introduce variations at the buses voltage magnitudes, which compromise the quality of the supplied electric energy. To assure high quality, some devices such as voltage regulators – VRs and capacitors banks – CBs, are installed to allow effective control of voltage magnitude, reactive power and power factor. The present work proposes a methodology to allocate simultaneously these devices using both Genetic Algorithms – GAs and Optimal Power Flow – OPF. The strategy proposed involves the adoption of GA for the allocation of CBs with specification for the type of bank (fixed or automatic) and the reactive power (kvar), as well as the allocation of VRs with adjustment of their secondary voltage. The OPF is responsible for the solution of the power balance equations, tap adjustments of the VRs that assure the voltage level at their exits according to the voltage level specified by the GA for the diverse load curve and for the attainment of the nominal current of the VRs allocated.


► We propose a methodology to allocate voltage regulators (VRs) and capacitors banks, simultaneously.
► It uses Genetic Algorithms and Optimal Power Flow based on the Interior Point Method.
► The OFP is responsible for the solution of the network and adjustments to the taps of the VRs.
