Distribution network load prediction distributed power supply containing

The present invention provides a method for forecasting load distribution network with distributed generation of the distributed power supply comprises a wind turbine and a photovoltaic system; comprising the steps of: collecting load prediction information; load prediction curve in the planning area; prediction in a distributed power supply output characteristic curve; grid on predicted load characteristic distribution curve with distributed generation. The present invention contemplates the output power characteristic of a distributed random by Monte Carlo simulation of the distributed power output curve, then the overall load characteristic curve obtained on the basis of distribution network load prediction on different sites, the overall final consolidated load characteristics and distributed power output characteristics, based on the principle of superposition characteristic time to get the payload distribution network in the characteristic curve, can solve the problem with the distribution network of distributed load forecasting power.
