Abstract

In deregulated power system, the implementation of DGs becomes relevant due to environmental and economical benefits. The presented paper has solved the problem of optimization of both position and size of DG to be placed in the RDS for the objectives of real power loss reduction and bus voltage profile improvement through Bat algorithm. The effect of optimal DG placement on different operational parameters has been evaluated. The proposed approach has been implemented for IEEE 69 bus RDS with constant power load per hour and variation of loads on 24 hours basis. Hourly variable load case has been analyzed for energy (KWh) saving analysis. The simulation results are discussed and compared with the previous results of different algorithms.
