Abstract

The invention discloses a distributed power source capacity and access position uncertainty-based power distribution network planning method comprising the following steps: an analysis model is built with a distributed power source being different in capacity and in access position in a power distribution network, and influence exerted on power distribution network operation parameters by grid connection of the distributed power source is researched based on different access combinations; constraint requirements for planning are formed according to the influence exerted on power distribution network operation parameters by grid connection of the distributed power source; according to the requirements for planning, a planning model is built; a planning result is obtained after the planning model is sovled. Via the distributed power source capacity and access position uncertainty-based power distribution network planning method, maximum absorption of any distributed and generated electricity connected to the power distribution network can be realized while safe and economical operation of the power distribution network is ensured, and strong adaptability can be fulfilled.

Description

technical field [0001] The invention relates to the technical field of intelligent distribution network, in particular to a distribution network planning method with uncertain distributed power supply capacity and access location. Background technique [0002] Distributed power generation (especially renewable energy) has become an important means for the power industry to cope with energy crisis and environmental protection due to its high efficiency, flexibility and sustainability. The access of distributed power generation can relieve the pressure of load growth and delay the upgrade of power grid And reduce the energy loss of grid operation. The active distribution network with extensive access to distributed power focuses on the autonomous control of local areas and the optimal coordination of the entire network, that is, it can use advanced information and communication technology and power electronics technology to achieve large-scale access to distributed power distr...
