Evaluation on Peak Load Balance of Power System Accessed by Large-Scale Wind Power

The peak load balance of power system is the key lo maintain its sialic stability.Wind power is urgent to be studied when accessed into the power system on a large scale.Based on mathematical models and algorithms applicable lo the calculation method on the peak load balance of power system with wind power,the corresponding calculation method is put forward.First design the operation mode of peak load shaving and the mode of wind power access based on the actual situation of this regional power grid,then simulate and calculate the surplus of peak load shaving in three modes of wind power access based on the actual data of the grid.Last,analyze the impact on peak load balance of power system coming from the access of wind power.The results shows that large-scale wind power access will bring notable' negative influence on peak load balance ol power system,the degree of influence closely relates to the modes of wind power access.
