Algorithm on optimal wind power capacity using peak load regulation restraints

The system peak load regulation is influenced more seriously since larger-scale wind power is integrated into power system. This paper analyzed the influence of wind farm operation characteristics to system peak load regulation. A planning method is established on wind farm optimal capacity, which based on system peak load regulating capacity and system ramp rate restraints. Aiming at maximum net income of wind farm, the paper established planning model and proposed iterative algorithm to solve it. An example is applied to demonstrate the effective of the algorithm and some analysis is done. The influence of electricity price to optimal installation capacity is indicated.
