Problems solved by technology

[0003] At present, the demand response model considered in distribution network planning is relatively simple, because on the one hand, the influence of specific operation means is generally not considered in the planning stage, and on the other hand, considering refined demand response in the planning stage will bring a large amount of calculation
However, with the continuous development of demand-side resources, the simple demand response model can no longer reflect the actual load characteristics and response capabilities

Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0044] In this embodiment, a distribution network planning method considering secondary response cost and energy substitution includes the following steps:

[0045] Step S1: Obtain relevant data of the distribution network, and construct a comprehensive demand response model;

[0046] Preferably, in this embodiment, on the one hand, transferable loads are considered to realize peak shaving and valley filling, and on the other hand, alternative loads are considered to realize electric energy replacement. The load relationship before and after demand response is as follows

[0047]

[0048]

[0049] Although the transferred load does not change the total energy consumption, it affects the user experience of energy use, so a certain economic compensation is considered; the replacement load does not affect the user's real-time energy consumption in t...

Abstract

The invention relates to a power distribution network planning method considering secondary response cost and energy substitution, and the method comprises the following steps: S1, obtaining the related data of a power distribution network, and constructing a comprehensive demand response model; S2, based on the comprehensive demand response model, correcting an objective function and constraint conditions, and constructing a power distribution network economic optimal planning model considering the comprehensive demand response; S3, solving the power distribution network economic optimal planning model considering the comprehensive demand response to obtain a comprehensive demand response scheme in the power distribution network. The comprehensive demand of the demand side is considered, the utilization efficiency and the operation stability of the power system are effectively improved, and various costs of the system are further reduced.

Description

technical field [0001] The invention relates to the field of distribution network planning, in particular to a distribution network planning method that takes into account secondary response costs and energy substitution. Background technique [0002] Power demand response can realize load shaving and valley filling through reasonable scheduling of demand-side resources, reduce system operating costs, optimize power consumption behavior of power users, and guide users to use power in an orderly manner. At the same time, considering demand response in the system planning stage can further delay power grid investment, optimize project sequencing, and obtain better economic and social benefits. Further, under the background of "carbon peaking and carbon neutrality", the promotion of electric energy substitution has become an effective means of carbon reduction on the demand side, and the potential of the load side will be further tapped. [0003] At present, the demand respons...
