Abstract

The invention provides a multi-target new energy source planning method and device. The method is applied to the technical field of the new energy source planning. The method comprises the following steps: collecting output data of a typical wind power plant and a photovoltaic power station; for new energy sources in different grid-connecting ways in the region, constructing a multi-target optimization model in the nearby consumption, minimum system network loss and minimum electricity purchasing cost; and determining the new energy source grid-connecting location and installed capacity according to the output data and the multi-target optimization model. The multi-target new energy source planning method and device provided by the invention can effectively improve the generation utilization efficiency of the new energy plant station in the region, and the wind-abandoning and light-abandoning risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of new energy planning, and more specifically relates to a multi-objective new energy planning method and device. Background technique [0002] In recent years, in-depth research has been carried out on the problem of site selection and capacity determination of new energy sources at home and abroad, from the perspective of the minimum operating cost of the distribution network, the minimum average power outage of the distribution network, the minimum active power loss of the distribution network, and the minimum equivalent carbon emissions of the system. , Optimal system voltage quality, or a combination of the above multiple optimization objectives to build an optimization model from multiple dimensions. Most of the related research is based on different control strategies of new energy, which are respectively treated as PQ type, PI type, PV type and PQ(V) type. [0003] However, in the existing technolog...
