A design method for heat storage capacity and heating power of electric heating

Abstract

The invention provides a method for designing the heat storage capacity and the heating power of an electric heating system, comprising the steps of determining the daily wind curtailment power of a wind farm in the heat supply period, designing the heat supply power and the heat storage capacity of the electric heating system, and designing the heating power of the electric heating system. The heating power of the electric heating system is designed according to the wind curtailment power curve of the wind farm, and abandoned wind power can be utilized to the maximum; the heat storage capacity of the electric heating system designed by the invention takes into consideration the scenario with least wind curtailment of the wind farm, and the quality of heat supply can be ensured under the condition that abandoned wind power is utilized to the maximum; and the heat storage capacity and the heating power of the electric heating system designed by the invention are minimized under the condition of ensuring the quality of heat supply, and the investment cost of the electric heating system is reduced.

Description

Technical field [0001] The invention relates to a design method, in particular to a design method of electric heating storage capacity and heating power. Background technique [0002] As a kind of clean renewable energy, the vigorous development of wind power can not only relieve the tension of electricity consumption, provide sustainable power for economic development, but also reduce the excessive dependence on traditional fossil fuels, and is important for energy saving and environmental protection.

Problems solved by technology

However, wind power has the characteristics of randomness and volatility, and the adjustment ability of the power supply is directly related to the level of wind power accepted by the grid.

The power supply in my country's "Three Norths" region is dominated by thermal power units, and the number of combined heat and power units is large. Under the heating needs of residents and industries in winter, combined heat and power units generally operate in the mode of "heating fixed power", resulting in the power peak-shaving capacity Significantly reduced, in order to ensure the active power balance of heating and power grid during the low load period, a large number of wind power had to be curtailed, which seriously affected the consumption of wind power
