The heating project utilizing abandoned wind power can improve the situation of insufficient peak load regulation space caused by the “determining power generation by heat” mode in northern China

but the economic benefit of combined heating capacity allocation with traditional boilers has yet to be demonstrated. On the basis of life cycle cost

the optimal capacity allocation of the combined heating system of electric heat transfer equipment

coal boiler and gas boiler is studied. Based on the construction of a hybrid heating system including electric boiler

heat pump

coal boiler and gas boiler

the life cycle cost of the alliance is taken as the objective function

the operating cost of the system under the condition of sufficient and insufficient abandoned wind power is taken into account while stable heating is provided. Based on the actual historical sequence data of abandoned wind power and heat load in Xinjiang area

genetic algorithm is adopted to solve the optimal model and carry out simulation.The result shows that

compared with the existing models

the combined heating system in this paper has the best economic benefit in the life cycle of the project

the timing distribution of the equipment heating power is realized while capacity allocation is optimized

it provides theoretical guidance for the planning and dispatching of the combined heating system including the heating project utilizing abandoned wind power.
