Reactive power optimization technology for wind farms considering the reactive power resources allocation cost

中文摘要英文摘要

文章提出了一种计及无功资源调配成本的风电场无功优化方法,实现了风电场在不同运行工况下的无功优化配置.该方法以风电场无功调配成本和网损组成的综合成本最小为目标函数,考虑风电功率波动对系统电压的影响,建立基于机会约束规划的风电场无功优化模型,采用改进内点法进行求解.所提方法通过设置无功成本系数,使风电场能够按实际运行需求调用静止无功发生器、储能设备和风机的无功,并优化风电场网损.通过在电压约束条件中预留电压安全裕度防止系统电压发生越限.在某实际风电场中验证了所提方法的可行性和优越性.

In this paper,a reactive power optimization method for wind farms considering the reactive power resources allocation cost is proposed to achieve the optimal reactive power control under different operating conditions.With the comprehensive cost composed of power loss and reactive power cost as the objective function,the reactive power optimization model is established based on chance-constrained programming,considering the influence of wind power fluctuations on voltage magnitude,which is then solved by the improved interior point method.According to the actual operating requirements,the proposed method can schedule reactive power of Static Var Generator(SVG),Energy Storage(ES)and wind generators in sequence by setting reactive power cost coefficients,and optimize the power loss of wind farm.The voltage violation risk is also controlled by reserving the voltage safety margin in the voltage constraint.In the end,the advanced and feasibility of the proposed method is verified by a simulation at an actual wind farm in China.
