Abstract
Description
technical field
[0001] The invention relates to a method for calculating the probability power flow taking into account the acceptance capacity of the power grid. Background technique
[0002] As large-scale new energy power generation is connected to the grid, the randomness and volatility of new energy power generation lead to more and more obvious node voltage or branch power flow limit violations during the operation of the power system, which reduces the safety of power system operation. Therefore, it is necessary to qualitatively and quantitatively analyze the impact of new energy generation access on the power system. In the aspect of testing the planning scheme or operation of the power system including new energy power generation, the traditional power flow calculation method can no longer reflect the system operation under the change of operation mode, and it is replaced by the probabilistic power flow calculation method that can reflect the probability characteris...
