Typically, wind power plants are structured in distant areas and distinct geographic conditions, and they are of great importance and sensitivity. Due to the alterable and irregular nature of wind speed, frequently, induction generators are used in wind turbines in order to convert wind energy to electrical energy. Optimal utilization of power plants is one of the most important issues in power systems utilizing and it has a lot of complexity due to the many constraints and parameters raised in it. The purpose of this research is the optimal utilization of the power plants by considering the constraints of the networks. Wind power plants have also been used as electric power generation units. Due to the uncertainty in the wind existence and the probability of the units’ emergency shutdown exit, Spinning Reserves have been used to institute the reliability of the system. In this study, a safe way has been presented to allocate reserve, so that according to the existing scenarios of wind, the worst scenario has been considered for allocating the reserve. The main criterion for LOLP reliability checking has been added to the system constraints in order to achieve the desired reliability of the power system. Another case studied in this study is the consideration of the effect of breaking loads on the spinning reserve of units and, ultimately, on the overall cost of the system. Also, in this study, a powerful intelligent method that is called the Particle Swarm Optimization (PSO) has been used to solve this problem.
