Power supply quantity dual-stage optimization scheduling method based on heat load regulation

Abstract

The invention discloses a power supply quantity dual-stage optimization scheduling method based on heat load regulation. The method includes the steps: S1 day-ahead scheduling stage: forecasting next-day load and wind power output and acquiring a heating load scheduling plan of next-day regulated wind power heating load according to heating load needed by a target supply area; S2 real-time scheduling stage: heating the target supply area according to the heating load scheduling plan, and regulating heat load within a preset range in real time to optimize scheduling of the heat load. The methodis simple to implement, heating can be scheduled based on heat load regulation, the regulation capacity and the heating performance of a thermoelectric unit are improved, heating use rate is increased, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of wind power heating, in particular to a two-stage optimal scheduling method for power supply based on thermal load regulation. Background technique [0002] At present, my country's central heating usually adopts the heat supply method of thermoelectric units, and thermoelectric units generally operate in the mode of "constant power by heat", and its output depends on the amount of heat supplied, resulting in a decrease in the electrical output of thermoelectric units during the winter heating period. The ability to adjust is very limited. By installing electric boilers and thermal power plants to provide heat together with wind power, the thermal power plant unit "thermoelectric decoupling" is realized. The electrical output of the thermal power unit no longer depends on the demanded heat load, which can improve the adjustment ability of the thermal power unit in the winter heating season. At present, win...

Problems solved by technology

[0004] But at present, when real-time scheduling is carried out, the temperature inside the heating area is usually kept constant when the heat is supplied by the wind-electricity-thermal power plant. The heating load cannot be adjusted, and the human body has a certain ability to adapt to the temperature. Adjusting the indoor temperature within a certain range will not significantly affect the comfort of people. The above-mentioned fixed heat load will cause energy waste and supply The electric output of the thermal unit is limited by the heating load, and the optimal output cannot be adjusted, which affects the regulation performance of the thermal power unit
