R.Pavithra Priya, N.Sivaraj , Dr.M.Muruganandam

Unit commitment (UC) is a optimization task planning operation in power system and is done by scheduled the generating units in on/off states. The UC problem is to minimize system total operating cost to meet forecasting load and reserve requirement while adhering to generator and transmission constraints to satisfy a given security level. The capability of using load, energy sources and energy storage in micro grid integrated with renewable energy sources (RES) by Electrical Vehicles(EV) with Vehicle-to-Grid. An intelligent UC with V2G for cost optimization is presented in this paper. And this paper presents a new solution to the UC problem based on Harmony Search Algorithm (HSA) is proposed. HS algorithm is based on musical improvisation process has employed to solve several power system problems like reactive power dispatch, power flow, unit commitment, economic dispatch, reconfiguration etc...
