The invention discloses a central heating network equivalence method considering temperature semi-dynamic characteristics. The central heating network equivalence method comprises the following steps: 1) acquiring related data of an electric-thermal integrated energy system; 2) establishing a central heating network equivalence model considering the temperature semi-dynamic characteristics; 3) projecting the feasible region of a heat supply network to a boundary by a heat power dispatching center to form a new constraint set, sending the new constraint set to a power dispatching center, and solving distributed dispatching of the electric-heat integrated energy system; and 4) outputting a distributed dispatching result of the electric-thermal integrated energy system. In the distributed dispatching of the electric-thermal integrated energy system, through the central heating network equivalence method, a power grid dispatching center and a heat supply network dispatching center do not need to carry out mass data iteration and frequent information interaction, only a small amount of boundary information needs to be interacted between the power grid dispatching center and the heat supply network dispatching center, iteration is not needed, the data privacy between different main bodies is well protected, the efficiency is improved, and good privacy is achieved.
Description
technical field [0001] The invention relates to the technical field of electric-thermal comprehensive energy system dispatching and optimization, in particular to a central heating network equivalent method considering semi-dynamic characteristics of temperature. Background technique [0002] With the access of renewable energy, the proportion of electric-thermal integrated energy system is increasing. In some areas, many heat and power cogeneration units adopt the mode of "setting electricity with heat" during the heating season, which has caused serious problems of "abandoning wind and light". The joint dispatch of electric-thermal integrated energy system can alleviate this phenomenon, and the heat storage capacity of the heat network also provides it with more flexibility and reduces operating costs. Although the centralized operation and analysis of electric-thermal integrated energy systems have been widely studied, the privacy issues of different subjects in electric...
