Applicable installation method of wind and solar power in power system

In this paper, an applicable method is introduced to install the wind and solar hybrid power in existing power system. Instead of using complex calculation, we performed the installation process based on the domain-link method. In order to testify the operation characteristics of power system after introduce wind and solar power, the maximizing decision method is applied to examine the operation condition by the targets of environment, economy, load and security. From the viewpoint of testing entire power system, except for the selected buses, all buses in system are also examined by synthetic target. The main advantage of this method is that it may be used in the power system both under planning and operation; and the installation site may be easily redetermined to obtain the appropriate weather condition for wind and solar power. The method introduced in this paper may be also used in large scale power system.
