Problems solved by technology

At the same time, if only the length of the outage and the rated power of the affected users are considered, it is difficult to formulate a differentiated power outage loss prediction and compensation mechanism for different users, and it is difficult to establish a reliability service market, which also inhibits reliability. Rational development of the capacity market

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments in no way limit the present invention.

[0043] The user's power consumption characteristics include the user's importance (in this patent, my country's traditional first-level, second-level and third-level loads are used to distinguish), the user's power consumption requirements (power quality requirements, reliability requirements, capacity backup requirements, etc.), user power consumption characteristics curves etc. Incorporating the power outage time into the user perception reliability evaluation method is to consider that two power outage events with basically the same scope in reality may have completely different impacts on the same load in the distribution network if they occur at different times. For example, attach figure 1 Shown is the electricity consumption characteristic curve of a typical single fami...

Abstract

The invention discloses a power distribution network reliability evaluation analysis method based on user perception. The method comprises the following steps: 1, carrying out pretreatment; The methodcomprises the following steps: 1) establishing a power distribution network reliability assessment module based on user perception, wherein the power distribution network reliability assessment module comprises a power distribution network annual average power failure frequency statistics module, a power distribution network annual average cumulative power failure duration statistics module, a power distribution network average every-time power failure duration statistics module and a power distribution network annual user perception expectation lack power supply statistics module; And 2) evaluating the reliability of the power distribution network by using the power distribution network reliability evaluation module established in the step 1). According to the power distribution networkreliability assessment analysis method based on user perception, some new factors capable of influencing the severity degree of power failure are brought into the user perception reliability assessment method; Power supply reliability services perceived by a user can be better described from a user side, and evaluation reference is provided for establishment of a reliability market, a capacity standby market and an energy storage market in the future.

Description

technical field [0001] The invention relates to the technical field of distribution networks, in particular to a method for evaluating the reliability of a distribution network based on user perception. Background technique [0002] At present, the reliability of distribution network mainly regards the duration of power outage and the amount of power outage load as the two decisive criteria for the severity of power outages. However, in addition to the above two indicators, there are other factors including the time point of power outage and the types of users affected by the power outage, which will also greatly affect the user's perception of system reliability and supply. The user's perception of the reliability level of power supply will greatly affect the formulation of reliable electricity prices in the future electricity market environment, the implementation of the direct purchase model, and the market willingness of energy storage and distributed investment installa...
