Abstract

The invention discloses a distributed photovoltaic sitting and sizing method for determining minimum permeability. The method comprises the following steps: recording the topological structure, system parameter and running state data of an active power distribution network from an electric network database to form a basic database; building a corresponding probability density function according to distributed photovoltaic power generation output and certain randomness in power consumption of a user; solving a target function with a biogeographical algorithm by taking maximum reduction in the carbon emission after distributed photovoltaic access as a optimization target and considering the constraint conditions of trend reverse feeding and distributed photovoltaic minimum permeability. By adopting the distributed photovoltaic sitting and sizing method, the trend reverse feeding caused by large photovoltaic installed capacity is avoided under the condition of ensuring the minimum photovoltaic permeability, and the reduction in the carbon emission is maximized; a power user is guided to use electric energy and low carbon resources more efficiently, and the carbon emission is lowered, so that the formation of an integral low-carbon electric power system is prompted.

Description

technical field [0001] The invention relates to a distributed photovoltaic site selection and capacity determination method for determining the minimum penetration rate, which belongs to the technical field of distributed power generation. Background technique [0002] Distributed photovoltaic: It is a photovoltaic power generation facility built near the user's site, and its operation mode is characterized by self-use on the user's side, surplus electricity connected to the grid, and balanced adjustment in the power distribution system. Distributed photovoltaic power generation follows the principles of adapting measures to local conditions, clean and efficient, decentralized layout, and nearby utilization, making full use of local solar energy resources to replace and reduce fossil energy consumption; it can not only effectively increase the power generation of photovoltaic power plants of the same scale, The problem of loss in boosting and long-distance transportation. T...
