Problems solved by technology

Restricted by the mode of "heating to determine electricity", the peak-shaving capacity of cogeneration units is very limited, resulting in insufficient reserve capacity for downward rotation of the system, and it is difficult to provide downward adjustment space for wind power consumption
[0003] In the traditional power system economic dispatching and unit combination problems, the central heating system has not been considered in the modeling

Abstract

The invention relates to a central heating system modeling method considering pipe network heat accumulation benefits and belongs to the field of multi-energy coupling system modeling. A central heating system model comprises four sub-models including a cogeneration unit model, a circulating water pump model, a heat exchange station model and a power supply network model, and each sub-model is formed based on corresponding constraint conditions. In the established model, the time quasi-dynamic property of a heat supply pipe network is considered, so that the heat storage property of the heat supply pipe network can be well reflected. The established model is suitable for being applied to heat supply network and power grid combined dispatching decision making.

Description

technical field [0001] The invention belongs to the field of system modeling of multi-energy coupling, and in particular relates to a modeling method of a central heating system considering the heat storage benefit of a pipe network. Background technique [0002] The pipe network of the heating network has good heat storage characteristics, that is, it has a strong delay in the heat change of the heating pipe network, which is reflected in the heat storage characteristics in the macroscopic time. In the central heating area in northern my country, the main way of heating in winter is large-scale combined heat and power central heating. At present, the combined heat and power units in northern my country mainly operate under the model of "power determined by heat", that is, the power generation output of the combined heat and power unit depends on the heat supply load, which restricts the output of heat-electricity, reflecting the heat-electricity model. coercive relationship...
