Economic evaluation of distributed generation in semnan power grid

This paper presents the potential for wind and solar energy in city of semnan and shows how much electric energy is now produced by renewable Distributed generation. distributed generation (DG) is expected to become more important in the future generation system. This paper gives the design idea of optimized PV-Solar and Wind Hybrid Energy System for distributed generation in semnan. the most important discussions about DG is economic aspect of DG. this paper is base on the empirical weather data obtained from Semnan meteorological organization. For this hybrid system, the meteorological data of Solar Insolation, hourly wind speed, are taken for semnan (Longitude 53deg.23´ and Latitude 35deg.34´) and the pattern of load consumption of feeder 20 kv are studied and suitably modeled for optimization of the hybrid energy system using HOMER software.
