Method and device for optimizing regenerative electric boiler for improving wind power consumption on the spot

Abstract

The invention provides a method and a device for optimizing a regenerative electric boiler for improving wind power consumption on the spot, wherein the method comprises: establishing a wind turbine model, an electrode boiler model and a regenerative tank model; establishing a multi-objective optimization model; and solving the multi-objective optimization model to obtain the optimization index ofthe regenerative electric boiler. The technical solution provided by the invention adopts the form of wind power heating to consume the abandoned wind, and integrates and connects the wind farm withthe heating device to the urban heating pipe network by using the regenerative electric boiler as a heating device for society heat supply. During the low-load wind-storage period, the electrode boiler starts to operate to increase the electric load in the grid, thereby increasing the wind power consumption, reducing the abandoned wind, and converting the electric energy into heat energy, a part of which is directly used for supplying heat to the residents during the period, and the other part is stored in the heat storage tank; while during the peak load period, the electrode boiler reduces the wind power supply or stops the operation, and the heat storage tank starts to supply heat, thereby improving the wind power consumption capacity on the spot by optimizing the heat storage type electric boiler finally.

Description

technical field [0001] The invention relates to the technical field of new energy power generation and accommodation, in particular to an optimization method and device for a thermal storage electric boiler that improves the on-site wind power consumption. Background technique [0002] At present, the phenomenon of wind power abandonment in the three northern regions mainly occurs in the winter heating period in the Northeast region. The heating period in this area is generally longer, and the abandonment of wind has caused a lot of waste of wind energy resources, which cannot benefit the people. At the same time, the lack of external transmission capacity prevents large-scale transmission of wind power to other places, and the only solution is to adopt local consumption. At the same time, cities in Northeast China generally have problems of insufficient heating capacity and low proportion of clean heating. Coal-fired boiler heating is still the main heating method in northe...

AI Technical Summary

Problems solved by technology

Although this scheme increases the consumption space of abandoned wind power and has a certain coal-saving effect, wind power has obvious characteristics of reverse output, which is large during the low load period and low during the peak load period, so the consumption of the electrode boiler Curtailed wind power is limited
