To guarantee the stable operation of a multi-infeed receiving-end power grid,an estimation method for its maximum power receiving capacity under static voltage stability constraints is proposed.First,the static voltage stabili-ty constraints are derived based on the singular value theory.Second,an optimal scheduling model for the multi-infeed receiving-end power grid considering static voltage stability constraints is established.Third,a piecewise linear solution method for the optimal scheduling model considering static voltage stability constraints is given,based on which an esti-mation method for the maximum power receiving capacity is put forward.Finally,a modified IEEE 39-bus system is test-ed to verify the effectiveness of the proposed method.
