Computation of Acceptable Wind Farm Capacity Under Peak Load Regulation Restraints

The ability of system peak load regulation impacted the acceptance degree of wind power to system,so the influence of wind power operation characteristics on system peak load regulation is analyzed,and a planning calculation method is proposed based on capacity of system peak load regulation and installed optimal capacity of wind power under constraints of peak load regulation speed.The objective of proposed method is the maximum net benefit of wind power operation,and the planning mode of the installed capacity of wind power is built.In addition,according to the constraints of system peak load regulation,by combining generation characteristics of wind power units under different wind condition and its probability,the planning model solved by iterative algorithm is presented and it is analyzed with example.In the end,the results are compared and analyzed according to several variation trends of load,and it is pointed out that variable load will influence the optimized stalled capacity of wind power,and the variation of off-peak load affect the optimized install capacity of wind power more obviously.
