Problems solved by technology

However, wind power is random, fluctuating and unpredictable, and large-scale wind power grid integration has brought great challenges to power system dispatching.
The power system in my country's "Three Norths" region is dominated by thermal power units. After large-scale wind power is connected to the grid, it is facing increasingly serious problems of system peak regulation and wind power consumption. Especially in the heating season, under the requirements of high heating load, thermal power Combined production units are often required to operate in the mode of "heating power" which further reduces the peak regulation capacity of the system

Embodiment Construction

[0049] A preferred example will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0050] The present invention is aimed at figure 2 For the combined electricity and heat system shown, a combined electricity and heat dispatching model is established for wind power consumption considering the elasticity of heat load and the characteristics of the heating network. The specific steps are as follows:

[0051] Step 1: Analyze the thermal comfort of heating users, and set the limited range of PMV segments according to the user's day and night comfort requirements;

[0052] S1: Thermal comfort and thermal inertia:

[0053] During the heating process, the temperature change of the heating medium usually lags behind the temperature change of the heat transfer medium. This thermal inertia allows the heating build...

Abstract

The invention provides an electric heating combined dispatching model considering heat load elasticity and heat supply network characteristics for wind power consumption, which comprises the followingsteps of: (1) analyzing the heat use comfort level of a heating user, and setting a PMV segmented limited range according to different day and night comfort level requirements of the user; (2) considering the required elasticity of the heat load, and converting the traditional heat balance equation constraint into an interval constraint; and (3) taking minimum total coal consumption and maximum wind power acceptance as an optimization target, and establishing an electric heating combined dispatching model considering heat supply network characteristics and heat load elasticity. The model is beneficial to broadening of a new idea of promoting wind power consumption by mining the adjustment potential of the demand side, and provides reference for electric heating economic dispatching underwind power integration.

Description

technical field [0001] The invention relates to the field of electric-heat optimization dispatching, in particular to an electric-heat joint dispatching model that considers thermal load elasticity and heating network characteristics for wind power consumption. Background technique [0002] With the depletion of fossil energy and the aggravation of environmental pollution, energy conservation and emission reduction at home and abroad have been increasing, and renewable clean energy such as wind power has developed rapidly. However, wind power is random, fluctuating and unpredictable, and large-scale wind power grid integration has brought great challenges to power system dispatching. The power system in my country's "Three Norths" region is dominated by thermal power units. After large-scale wind power is connected to the grid, it is facing increasingly serious problems of system peak regulation and wind power consumption. Especially in the heating season, under the requirem...
