Optimal Power Flow Using Distributed Generation and Conservation Voltage Reduction Techniques for Micro-Grids

Voltage control is critical in power systems operation and control. With the increase in using distributed generation DG, it becomes essential to ensure that voltage stability is main-tained. This work studies using DG and conservation voltage reduction CVR for improving voltage profile, reducing generation cost, and power loss. The size and location of the DG was optimized based on the voltage profile criterion. The buse's voltages were reduced to the lower band to decrease generation cost and total power loss. Optimal Power flow using PSO algorithm was implemented to investigate the power system voltage profile, 30 bus IEEE systems is used in this work. The results showed that accompanying DG with CVR can reduce generation cost and power loss by 13.14 and17.22.
