ANALYSYS OF WIND POWER VALUE TO POWER SYSTEM OPERATION

In the view of power system operation a stochastic simulation based method of quantitatively calculating the value of wind power to power system operation is presented. The variations of power system operating modes, caused by integration of wind power generation,and accordingly the change of generation costs is qualitatively described. According to the marginal generation cost of conventional generators the constitution of wind power value is analyzed. It is pointed out here that the wind power value depends on the characteristics of wind resource at the location of wind farm, the technical parameters of wind power generators, the proportion of load of wind power to the whole power system and the energy consumed characteristics of thermal generators which parallelly operate with wind power generation.The numerical examples on calculating wind power value and sensitivity analysis are given.The conceptual analysis method used in this paper is also suitable for complicated system.
