NEW METOD TO MODIFY THE LOAD DURATION CURVE

Peak power demand in national interconnected system is occured in July and August , because of cooling systems such as chilers. About 30 percents of total generated electrical energy in summer is used for cooling purposes.[3] Because of unequality between demand and generation transmision and distribution networks, power plants and electrical eq uipment are damaged severly. The best way to modify the load duration curve (in IRAN) is subtituting of compressoring cooling systems with absorbtion refrigeration systems[7,8] In this paper , absorbtion and compressoring cooling systems are compared at first , and then effects of this sujjestion on load duration curve electrical energy and demand components are described.
