A thermal storage electric boiler optimization method and device for improving wind power on-site consumption

Abstract

The present invention provides a heat storage electric boiler optimization method and device for improving the on-site consumption of wind power. The method includes establishing a wind turbine model, an electrode boiler model, and a heat storage tank model; establishing a multi-objective optimization model; and solving the multi-objective optimization model , to get the optimization index of regenerative electric boiler. The technical solution provided by the invention adopts the form of wind power heating to absorb the abandoned wind, uses the heat storage electric boiler as the heating device, integrates the wind farm and the heating device, and connects them to the urban heating pipe network in parallel to provide social supply. Heat; during the period of low load and wind abandonment, the electrode boiler starts to operate, increasing the electricity load in the grid, thereby increasing the amount of wind power consumption, reducing wind abandonment, converting electric energy into heat energy, and part of the heat energy is directly used for heating for residents during this period. Part of the thermal energy is stored in the heat storage tank; during the peak load period, the electrode boiler reduces wind power heating or shuts down, and the heat storage tank starts to supply heat. Finally, the heat storage electric boiler optimizes and improves the local wind power consumption capacity.

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
