In this paper, the influence of presence of wind and Underwater Compressed Air Energy Storage (UWCAES) and coordination of them is investigated. Nowadays, regard to incremental penetration of units, which make uncertainty in power systems, construction of large storage units, which cover and manage probable curtailments and unbalancies, assume more importance. These unpredictable curtailments cause terrible troubles at clearing time of spot market for operation of system. Also, in order to have more optimal operation, the appropriate decision should be made at suitable time so as to diminish the commitment of expensive thermal power plants. The amount of generated power at delivery time due to existence of uncertainty in generation and forecasted demand usually differs from forecasted power. Moreover, in one hour ago commitment programming the amount of generation of each unit can be dispatched more exactly, so that the constraints can be satisfied and objective function be led to optimum point. Furthermore, the curtailment at real time can have less unbalancy. However, the operator because of lost time and operation constraints have less dispatch ability in order to reach to most optimum point. Hence, a program should be made in order to help operators to make decision in one hour ago or real clearing time. Another Program is written to help operator to analyze and make decision while clearing day–ahead market. The conclusions show the benefits of presence of a storage unit in system, which increase profit of wind units and decrease the market clearing price, commitment of expensive units, while satisfying peak loads and thermal generation cost of system and diminish rick of commitment of units in wholesale power market, which have uncertainty, and support them to participate in a pool power market.<\div>
