Embodiment

[0083] Embodiment A method for evaluating the importance of users in a photovoltaic user group based on the TOPSIS method

[0084] This embodiment includes the following steps:

[0085] 1. Establish the system structure of photovoltaic user groups;

[0086] 2. Establish a revenue model for photovoltaic users;

[0087] 3. Evaluate and rank the importance of photovoltaic users in the photovoltaic user group.

[0088] Wherein, step one includes the following steps:

[0089] A1. Determine the operating framework of photovoltaic user groups based on internal electricity prices

[0090] Such as figure 1 Shown is a simplified diagram of the operation framework of the photovoltaic user group established in this embodiment. It is composed of n photovoltaic users and the only operator. Conduct electricity trading with the grid;

[0091] Grid electricity price refers to the electricity price directly traded between photovoltaic users and the grid;

[0092] A2. Set the electricity ...

Abstract

The invention discloses a TOPSIS method-based importance evaluation method of user in a photovoltaic user group. The method comprises the following steps of: firstly, establishing a system structure of the photovoltaic user group; secondly, establishing an income model of the photovoltaic user; and finally, evaluating and sequencing the importance of the photovoltaic users in the photovoltaic usergroup. Aiming at a photovoltaic user group implementing internal electricity price, the income essence of an operator is analyzed, and a method for calculating the contribution value of photovoltaicusers in the photovoltaic user group to the income of the operator is provided based on a cooperative game theory. According to the method, importance evaluation indexes of photovoltaic users are defined from three aspects of the photovoltaic users, an operator and a power grid, importance evaluation and sorting are carried out on the photovoltaic users in a photovoltaic user group based on a TOPSIS method, and stability and development of the photovoltaic user group are further promoted. According to the method provided by the invention, ranking under comprehensive evaluation is more reasonable and fair. The method is suitable for the technical field of electric power, and is used for evaluating the importance of the photovoltaic users in the photovoltaic user group.

Description

technical field [0001] The invention belongs to the technical field of electric power trading and is used for evaluating the importance of users in a photovoltaic user group, in particular to a method for evaluating the importance of users in a photovoltaic user group based on the TOPSIS method. Background technique [0002] Distributed photovoltaic power generation system, also known as distributed power generation or distributed energy supply, refers to the configuration of smaller photovoltaic power generation and power supply systems at the user site or near the power consumption site to meet the needs of specific users and support the economy of the existing distribution network. operation, or both. [0003] In the context of "coal to electricity", a large number of photovoltaics connected to the distribution network will have a certain adverse impact on the distribution network system. In addition to considering the elimination of these unfavorable factors from the di...
