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