Heat supply network equivalent modeling method

Abstract

The invention provides a heat supply network equivalent modeling method. The method comprises the steps of building a centralized heat supply primary pipe network system mathematical model according to a fluid network modeling technology; performing equivalent aggregation on the built mathematical model so as to acquire a model parameter; and checking whether deviation exists or not between the model parameter and measured data. The modeling method provided by the invention is based on heat transfer and fluid mechanics principles and a power system, and the mathematical model built based on the fluid network modeling technology conforms to physical characteristics of an actual heat supply network; simplification and checking for a large complex heat supply system model are realized through topological structure simplification, key parameter identification and field measured data, and the calculation speed and the accuracy of a heat-power joint optimization model are improved.

Description

Technical field [0001] The invention belongs to the field of power systems, and specifically relates to an equivalent modeling method for a heating pipe network. Background technique [0002] With the gradual depletion of fossil fuels and the gradual emergence of the problem of comprehensive optimization and adjustment of the energy structure, countries in the world are increasingly aware of the development of new energy. As the representative of the most developed renewable energy power generation, wind power has received more and more attention in recent years, and its development and utilization have developed rapidly. However, because the output of wind power depends on the wind, it is unstable in time and uneven in space. The characteristics of randomness and volatility, as well as anti-peak shaving, make the problem of wind power consumption more prominent, and the phenomenon of wind abandonment is common and serious. [0003] The heating in some high latitude areas is mainl...
