The invention discloses a method and device for establishing a distributed power source planning mathematic model. A comprehensive evaluation index planning adaption function is constructed accordingto a planning adaption function and a scene occurrence probability, the adaptation of the planning scene under the random environment is assessed from the angle of the probability, and a planning model is established based on the above method. The technical problem that distributed power source can play the deterioration effect when being operated under some conditions since the planning method according to nominal output in the prior art cannot guarantee the power distribution network of the distributed power source to satisfy various operation constraint conditions in the operation is solved.
Description
technical field [0001] The invention relates to the field of distribution network planning, in particular to a method and device for establishing a distributed power supply planning mathematical model. Background technique [0002] As an alternative to increasing the capacity of the distribution network, distributed power generation has attracted the attention of planners for its economical, flexible, environmentally friendly and avoidable or delayed power grid construction. The existing planning schemes mainly consider the network loss under the maximum and minimum operation modes. Minimal or cost-optimal is the planning model. [0003] However, the power output of various new energy forms of distributed power connected to the distribution network is greatly affected by meteorological conditions, with frequent fluctuations and large amplitudes. Considering that the distributed power connected to the distribution network is basically not controlled by dispatching, The adjus...
