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 family

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.
