Abstract

The invention discloses a power distribution network investment demand determination method and device based on combined prediction, equipment and a storage medium. The method comprises the following steps: carding factors influencing the investment demand of a power distribution network based on a fishbone diagram method; based on a grey relational analysis model, screening factors to obtain key factors influencing the investment demand of the distribution network; obtaining medium and low voltage distribution network investment scale and key factor historical data; establishing a distribution network investment demand prediction model by using a support vector machine method, a linear regression method and a grey prediction method; and inputting the key factors, the medium and low voltage distribution network investment scale and the historical data of the key factors into the distribution network investment demand prediction model to obtain a prediction result. Through the above mode, the method can achieve the precise prediction of the investment demands of the medium and low voltage distribution network, and provides a decision basis for a power grid enterprise to improve the lean level of the investment of the distribution network.

Description

technical field [0001] The present application relates to the technical field of medium and low voltage distribution network investment, and in particular to a method, device, equipment and storage medium for determining distribution network investment demand based on combination forecasting. Background technique [0002] In recent years, in order to adapt to the situation of rapid economic and social development, power grid companies have invested large-scale funds in the construction of medium and low voltage distribution networks, and have carried out transformation and upgrading of urban and rural medium and low voltage distribution networks, effectively supporting the rapid growth of electricity demand and reliable power supply. Continuous improvement of performance and power quality. In the case that the investment scale of medium and low voltage distribution networks continues to remain high, there are also problems such as heavy investment, low income, heavy project ...
