Locating and sizing of distributed generations considering local consumption and power export potential

Abstract

This paper proposes an optimal locating and sizing method of distributed generations (DGs) considering local consumption and power export potential. Based on the analysis of seasonal and temporal characteristics of different types of DGs and load, the proposed DGs locating and sizing model, is to minimize the total costs of DGs depreciation, network power losses, and redundant power. Under the premise of load demand locally satisfied, the optimal location and size of DGs is obtained by reducing the redundant power of DGs. Finally, the IEEE 33-bus test system is applied to validate the effectiveness and practicability of the proposed method.
