A Flexible Model Based on Correlation of Load Type and Components for Distributed Generation Allocation

Sufficient reduction in energy loss is achievable through optimally placing the distributed generation (DG) units on distribution buses, where role of load power is very significant in the process. Due to this, is very important to accurately model the demand side to show the behavior of electricity end-users in an efficient manner. The behavior of loads is not static but rather dynamic, constantly varying with voltage magnitudes depending on the consumer type. Notwithstanding, presenting loads in terms of constant-current, constant-impedance and constant-power components is very practical. Therefore, the determination of the relation that connects load components and load types can help to predict a more reliable DG allocation model. In that regard, this present study has mathematically formulated the relationship between load components with consumer type in order to give an efficient DG placement formulation. The formulation was tested on the 33-bus distribution network and the results proved that the proposed framework is optimal for obtaining accurate solution in a relatively short time as compared to exact models of DG allocation.
