Also, candidate generation options assuming different tariff have been shown in Table \ref{tab:7} and Table \ref{tab:8} . In calculation of Table \ref{tab:7} , the values of tariff for windy and solar power plants have been considered 2. Then, it can be observed that with this tariff, solar power plants are not competitive case in electricity market and they have not any place among candidate options, but windy power plant are more competitive.
