Modeling of renewable energy resources for generation reliability evaluation

The modeling of various renewable energy resources is proposed by considering daily operation profile. The forced outage rate of renewable unit can be obtained by using the equivalent forced outage rate. Generation reliability is then evaluated under the presence of renewable energy resources. The loss of load probability and the effective load carrying capability are used as reliability index and capacity contribution on reliability, respectively. A test system is built by scaling down the existing generation portfolio of Thailand. Numerical results are then provided and discussed under various loading conditions and penetration levels of renewable energy resources.
