Abstract

The invention discloses a power distribution network planning method, system and device. The method comprises the following steps: determining a planning demand of a power distribution network in a target area, a parameter range of photovoltaic equipment, a parameter range of the power distribution network and a photovoltaic output prediction value, constructing a power distribution network planning model, and solving the power distribution network planning model by adopting a multi-target optimization algorithm to obtain a planning scheme of the power distribution network. According to the invention, the parameter range of the photovoltaic equipment and the parameter range of the power distribution network are determined according to the planning requirements, and the proper parameter range is determined from the actual requirements, so that the waste of resources is avoided; photovoltaic output is predicted to ensure that photovoltaic power generation is consumed as much as possible;and then, the power distribution network planning model is constructed, the planning scheme of the power distribution network is obtained by solving the power distribution network planning model, collaborative planning of the network frame topology and the photovoltaic equipment is achieved, mutual restriction of the network frame topology and the photovoltaic equipment is reduced to the greatestextent, the distributed photovoltaic consumption rate is maximized, and waste of power resources and energy sources is reduced.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a distribution network planning method, system and equipment. Background technique [0002] In recent years, with the rapid development of new energy power generation technology, new energy power generation has gradually played a huge role in the power grid. With the promotion of photovoltaic poverty alleviation and other projects, the penetration rate of photovoltaics on the distribution network side has gradually increased, and the investment and construction of photovoltaics on the distribution network side has increasingly become a topic of general concern. [0003] However, at present, the investment and construction of photovoltaic equipment is often planned and transformed in the existing stock distribution network. In this process, it is often restricted by many factors such as the topology of the distribution network frame and the transmission capacity of the distribution n...
