Problems solved by technology

However, the output of new energy such as wind power and photovoltaic power generation has the characteristics of volatility and uncertainty. When the proportion of new energy in the power system is relatively small, the fluctuation of new energy can be regarded as a load forecast error; but when the proportion of new energy is large enough to a certain extent , the fluctuation and uncertainty of its output will bring many challenges to the power grid

Embodiment 1

[0071] In S1, the notification time for Type B demand response resources is 15 minutes in advance; the notification time for Type C demand response resources is 5 minutes in advance. The notification time for Class B demand response resources can also be longer than 1-2 hours. Correspondingly, refer to figure 1 , the calculation periods of the day-ahead-day-real-time scheduling plan are 24 hours, 15 minutes and 5 minutes respectively.

[0072] In S2, the demand response quotation curve data corresponding to various types of incentive demand response resources, that is, the relationship curve data between the increase or decrease of loads and quotations of various incentive type demand response resources at different time periods. Quote curves are provided by load aggregators.

[0073] refer to figure 2 , to explain the LA segment quotation curve. figure 2 There are 5 segments in the quotation curve. The abscissa greater than 0 means that the load aggregator increases the...

Embodiment 2

[0107] refer to figure 1 , when the present invention is actually implemented, it judges each moment while scheduling execution.

[0108] Judgment block 1-whether the 24-hour cycle is reached: it is judged whether the rolling scheduling has accumulated for 24 hours. If yes, it means that a new day-ahead scheduling is required, and enter judgment box 2 after formulating the day-ahead scheduling plan;

[0109] Judgment box 2-whether the 15-minute cycle is reached: it is judged whether the rolling scheduling has accumulated for 15 minutes. If yes, it means that the next 15-minute intraday scheduling needs to be carried out, and enter judgment box 3 after formulating the next 15-minute scheduling plan;

[0110] Judgment block 3—whether the 5-minute cycle is reached: judge whether the rolling scheduling has been carried out for 5 minutes in total. If yes, it means that the next 5-minute real-time scheduling needs to be carried out, and enter the next moment; if not, it means tha...

Abstract

The invention discloses a demand response resource multi-time scale rolling scheduling method for new energy consumption. The method comprises calculation of a day-ahead scheduling plan, calculation of an intraday scheduling plan and calculation of a real-time scheduling plan. The invention aims at different characteristics of different new energy prediction precisions at different time scales, comprehensively considers the multi-time scale characteristics of demand response resources and good interaction between demand side resources and power generation side resources such as wind power, photovoltaic, conventional start-up units and quick start-up units, considers incentive demand response resources at different time scales and price-type demand response resources affected by real-time electricity prices, realizes the rolling schedule of the demand response resources of the day-ahead, intraday and real-time time scales, and with the cooperation of multiple time scales, can ensure thesafe and stable operation of a power system and the consumption of new energy, as well as the coordinated scheduling of the demand response resources at different time scales. The method of the invention has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of power dispatching, in particular to a multi-time-scale rolling dispatching method for demand response resources that accommodate new energy sources. Background technique [0002] With the depletion of fossil energy and the aggravation of environmental problems, the country's efforts in energy conservation and emission reduction have been continuously intensified, and renewable energy such as wind energy and solar energy has developed rapidly. However, the output of new energy such as wind power and photovoltaic power generation has the characteristics of volatility and uncertainty. When the proportion of new energy in the power system is relatively small, the fluctuation of new energy can be regarded as a load forecast error; but when the proportion of new energy is large enough to a certain extent , the fluctuation and uncertainty of its output will bring many challenges to the power grid. [0003] Dema...
