Embodiment Construction

[0061] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] Such as Figure 5 As shown, the demand response effect evaluation method based on fuzzy comprehensive analysis of the present invention comprises the following steps:

[0063] 1. Determine the evaluation index of demand response scheduling effect, based on the demand of the power grid, evaluate the gap between the demand response event and the expected goal of the event, as well as the actual effect of the event, and determine the evaluation index of demand response dispatching effect, including reliability index, economic There are three categories of indicators, namely, safety indicators and environmental protection indicators, such as figure 1 As shown, among them,

[0064] 1.1. The reliability index includes the response time reliability index R time , Response mode reliability index R type and response capacity reliabi...

Abstract

The invention discloses a demand response effect evaluation method based on fuzzy comprehensive analysis. Based on power grids and social demands, reliability, economical efficiency and environmental protection are used as three indexes for measuring a demand response effect. According to the reliability index, the participation way of a use, response time and the reliability degree of response capacity are mainly measured in the demand response process. According to the economical efficiency index, the cost of the unit response capacity for carrying out a demand response and the reduction of the power grid valley-to-peak difference due to a demand response event are mainly measured. According to the environmental protection index, after the demand response is carried out, measurement is mainly carried out from the environmental pollutant discharge quantity and the user energy consumption level. In the index calculation process, the indexes difficult to quantize are expressed in a relative value or level mode, and understanding and calculation are easy. In the index solution process, a fuzzy comprehensive analysis method is adopted, the problems that the evaluation indexes are fuzzy and difficult to quantize can be solved well, and the method is suitable for different demand response stages of the different power grids.

Description

technical field [0001] The invention belongs to the technical field of electricity service, and in particular relates to a demand response effect evaluation method based on fuzzy comprehensive analysis. Background technique [0002] With the help of emerging IT technologies such as the Internet of Things, cloud computing, and data mining, smart grids can flexibly manage, dispatch, and integrate demand-side resources through technologies such as intelligent measurement, high-efficiency control, and high-speed communication. The way of power rationing has changed to load transfer control, interruptible load control and maximum demand control relying on power electronics and communication technology, and demand response is becoming a research hotspot in demand side management. With the continuous advancement of the construction of pilot cities for demand-side management, under the influence of different incentives and electricity price mechanisms, demand response is entering th...
