| Summary: | Abstract To ensure the quality of the energy in distribution networks, configurations of voltage regulators (VRs) and Shunt Capacitor Banks (BCshunts) are traditionally used along the feeders. Series Capacitors Bank (BCseries) along the feeders can also help to improve the power quality. In this paper, a strategy is proposed based on a mathematical formulation for an optimization problem where the aim is to allocate and size BCshunts and VRs (as traditionally implemented in the electricity sector) together with BCseries in distribution networks. These devices are allocated using Genetic Algorithm together with Multiperiod Optimal Power Flow. Using the proposed strategy, it is analyzed the network performance by studying: (i) the allocation of VRs and BCshunts simultaneously, and (ii) the allocation of VRs, BCshunts and BCseries simultaneously. The objective function is based on the minimization of active power loss costs, penalties for voltage violations, and equipment costs. Results are presented for a 90-bus radial distribution system which show that the use of BCseries is suitable for feeders with abrupt load variations, and that this approach competes positively with the simultaneous allocation of VR and BCshunt devices, with shorter investment amortization times and improved quality indices. |
