Optimum voltage regulator placement in a radial power distributionnetwork

摘要

A computer algorithm for optimal voltage control with voltagenregulators, suitable for large radial distribution networks is given innthis paper. An objective function concerning the total cost of thenvoltage regulators (investment and maintenance cost) as well as the costnof losses of the examined networks is developed and constitutes the basenof the algorithm. This algorithm makes the initial selection,ninstallation and tap setting of the voltage regulators, which provide ansmooth voltage profile along the network, utilizing former algorithmsnsuitably modified and optimized. Then it attempts to minimize the numbernof the initially selected voltage regulators as much as possible, bynmoving them in such a way as to control the network voltage at thenminimum possible cost (maximization of the objective function). Thenalgorithm is fast, efficient and reliable as its application tonpractical distribution networks shows
