Voltage profile improvement and power loss minimization of new haven injection substation for optimal placement of DG using harmony search algorithm optimization technique

The main importance of a power grid is to transfer electrical energy from the production consumption, while maintaining an acceptable reliability and voltage quality for all customers. role distributions have centralized plants distributing electricity through Distributed Generation (DG) which reduces Power Loss on transmission distribution station also improve profile by optimization. This research work analyzes New Haven injection substation optimal placement DG generation based wind renewable source Distribution network stability using Harmony Search Algorithm. model developed was simulated MATLAB/SIMULINK software. applied new improved Algorithm integration in with positive impact operation between 0.95 1.05p.u reactive improvement minimization line losses. total system without are 338.712KW 307.9KW. Also, profiles sixteen faulty buses stabilized efficient performance substation. Hence, percentage 27.23%. Therefore results, there reduction when optimised system.
