| A wide penetration of DG in distribution system, operation and designed of these networks has changed. The reactive power management and optimal capacitor placement are the most important characteristics in distribution networks on which the impact of the DGs should be studied. Type of distributed generation (DG) technology, modeling and their diverse capacity can affect the optimal capacitor placement in the distribution systems. In this research fixed and switchable capacitors allocation in distribution networks in the presence of scattered generation units is presented. As a cost function in optimization procedure, cost of energy loss, installation and purchase costs of capacitors and cost of peak power loss are considered. Genetic Algorithm with new coding and operators are used for optimization. One of the significant characteristics of the proposed GA–based method is providing the switching table for allocated capacitors in various load levels. |
