Embodiment

[0077] Taking the wind power output curve of a certain day in Gansu Province as an example, the GAMS software is used for simulation. The total running time of the simulation calculation is 24 hours, and the unit scheduling time Δt is 15 minutes. The flow velocity v of hot water for urban heating is 2.5m / s. Considering the heating efficiency, the heating range of the power plant is about 9km, and the distance l of water supply pipes between each user group is 2.25km. EHP is 3. The total capacity of the distributed energy storage system of each user group is 200MW, and the central heating of the users is provided by 25 cogeneration units C135 / N150-13.24, and the heating load of the users is Q L (t,l) is 4425MW. Enter the simulation parameters, get Figure 3 to Figure 5 The simulation results. image 3 is the power load curve before and after dispatching, and it can be concluded from the figure: before dispatching, there is a large gap between the maximum value and minimum va...

Abstract

The invention discloses a wind power grid connection control method based on user side demand response and distributed energy storage, which relates to the field of distributed energy storage and power grid connection technologies. The wind power grid connection control method based on user side demand response and distributed energy storage mainly aims to solve the problems that output of a windpower generator set is uncertain due to wind speed change and wind power output relies on power grid system peak value adjustment, adjusts power generation output and heat supply output of a combinedheat and power generation unit, meanwhile, controls a distributed energy storage system and distributed heat pumps to respond to operation at the user side, compensates for adjustment amounts of the power generation output and heat supply output of the combined heat and power generation unit accordingly, reduces load peak and off-peak difference equivalently, decreases peak regulation capacity ofwind power grid connection, can obtain extra load peak value adjustment capacity, and improves the problems in wind power grid connection.

Description

technical field [0001] The invention belongs to the technical field of distributed energy storage and wind power grid connection, and in particular relates to a wind power grid connection control method based on user-side demand response and distributed energy storage. Background technique [0002] As we all know, wind energy is random and unstable, resulting in large and irregular changes in the output power of wind power generators within a day. From the average daily output power of wind farms in a year, the difference between the maximum and minimum power generation per day is at least about 40 to 50 times. From a microscopic analysis of the output power changes within a day, wind power is still in a very unstable state within 24 hours, and the output power (MW) fluctuates randomly between 0 and 100. At the same time, wind power has the characteristics of anti-peak regulation, and the output of wind power generation is often larger when the power load at night is at a l...
