Decision making to procure electrical energy of large consumers in the presence of wind turbines

Consumers seek an economic way to procure electrical energy in the competitive electricity market. These ways includes: bilateral contract, participating in the pool market and generating the energy by the self-generating units. Electrical energy should be bought in appropriate time with the best price. In the other hand, effects of increasing the renewable energies have been investigated in the recent years. Considering the uncertainty of these sources increases the complexity of the decision making process as well as un-favorite decision making situations. In this paper, decision making to procure the electrical energy has been investigated in the presence of wind turbine uncertainty. The electricity energy prices and the electricity load demand have also uncertainty. Considering three sources of uncertainty increases the decision making risk. In this regard, an appropriate risk index has been selected to decrease the risk in the system. A simulation is also conducted to demonstrate the wind generation effects. Efficiency of the proposed method has been verified with various simulations.
