Multi-wind-field bidding method for electric heating and promoting wind electricity consumption on spot

Abstract

The invention discloses a multi-wind-field bidding method for electric heating and promoting wind electricity consumption on spot, belonging to the electric power system technology field. Targeting a minimum electric consumption cost of a thermal storage type electric boiler system, the multi-wind-field bidding method uses wind curtailment power prediction data and a quotation chart which are provided by a wind field according a thermal load requirement of the heat storage electric boiler system, adopts a particle swarm to perform optimization and realizes the minimum electric consumption cost of the thermal storage electric boiler system under a multi-wind filed bidding mode. The multi-wind-field bidding method for electric heating and promoting wind electricity consumption on spot can promote the consumption of wind curtailment electric quantity, improves electricity selling incomes, benefits the wind electricity consumption on spot, can improve a utilization rate of power transmission properties of a power grid company in off-peak hours and effectively reduces electricity buying cost of the thermal storage electric boiler. As a result, the multi-wind-field bidding method for electric heating and promoting wind electricity consumption on spot can effectively promote popularization and application of electric heating in heat supplying northern regions of China in winter.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a multi-wind field bidding method for electric heating and heating to promote wind power on-site consumption. Background technique [0002] my country is rich in wind energy resources, and the wind power industry is developing rapidly. By the end of 2016, the installed capacity of wind power in the country had reached 148.64 million kilowatts. At the same time of rapid development, since my country's wind power is mainly concentrated in the three north regions with poor grid flexibility, it is difficult to send wind power outside, leading to serious wind curtailment problems. In recent years, heating in winter in northern my country has brought serious environmental problems. Smog pollution has interfered with people's normal production and life, and it is urgent to solve the problem of smog. In order to solve the problems of wind power consumption and...

Problems solved by technology

Under the current operation mode, the income of the wind farm and the thermal storage electric boiler system is considered as a whole, which includes the cost of wind farm abandonment and selling electricity, the cost of the thermal storage electric boiler system purchasing electricity from the grid and other The income from heat sales, under the current model, the regenerative electric boiler system is attached to the investment subject and does not have independent profitability, which limits the promotion and application of abandoned wind power heating. With the new round of power market reform Continue to deepen, in order to promote the regenerative electric boiler system in the northern winter heating area to alleviate the problems of abandoned wind and smog pollution, it is necessary to encourage independent entities to invest in the construction of regenerative electric boiler projects
