Two-stage optimal scheduling method of power supply based on thermal load regulation

Abstract

The invention discloses a two-stage optimal scheduling method for power supply based on thermal load regulation. The steps include: S1. A day-ahead scheduling stage: predicting the next day's load and wind power output, and obtaining the next day's wind power adjustment according to the heat supply required by the target supply area Heat supply scheduling plan for heat supply; S2. Real-time scheduling stage: supply heat to the target supply area according to the heat supply scheduling plan, and adjust the heat load in real time within the preset range to optimize the heat supply in real time scheduling. The invention has a simple realization method, can realize heat supply scheduling in consideration of heat load adjustment, improves the adjustment ability and heat supply performance of the thermoelectric unit, improves heat supply utilization rate, and reduces environmental pollution.

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
