| Abstract: Integrating uncertainties of the load demands and those associated with capacitor allocation in radial distribution feeders is the aim of the present paper. Modeling of the uncertainties accompanying the load parameters is important in relation to the problem of reactive power compensation in distribution systems using capacitors allocation. Interval mathematics provides a powerful tool for modeling uncertainties. The uncertainties related to load demand are modeled by solving the load flow using a developed interval backward/ forward sweep technique. The interval voltage outcomes are used in the governing equations of the capacitor allocation analysis. Interval distribution functions defining the real power losses and the voltage sensitivity are introduced to, sequentially, order the sensitive nodes that require compensation. A heuristic technique is formulated to determine the interval capacitor size, interval maximum cost saving, and the corresponding interval loss reduction. A significant improvement in the voltage profile is achieved using the proposed technique. Implementation of the technique is demonstrated using two realistic radial distribution feeders. | ||||
