Title:
PROBABILISTIC LOAD FLOW CALCULATION METHOD CONSIDERING ADMITTING ABILITY OF POWER GRID
Document Type and Number:
WIPO Patent Application WO/2017/157058
Kind Code:
A1
Abstract:
A probabilistic load flow calculation method considering power grid acceptance capacity, comprising the following steps: step 1, building a cumulative distribution function of a new energy power generation power variable according to the acceptance capacity of the power grid for new energy generation power, wherein the cumulative distribution function is described in the form of a piecewise function; step 2, calculating a sampling frequency of the new energy power generation variable in each of sections by using a proportional distribution principle, according to the built cumulative distribution function F(pk) of the new energy power generation power variable, and then by using a Latin hypercube sampling method, sampling the new energy power generation power variable in each of sections to build a sample matrix of the new energy power generation power variable; step 3, using the sample matrix of the new energy power generation power variable as an input variable to perform the probabilistic load flow calculation, to obtain a disperse result of an output variable, and fitting with an empirical distribution function to obtain a probability distribution function of the output variable. The method not only extends the application range of the Latin hypercube sampling method, but also ensures the accuracy of calculating.
