Abstract

The invention relates to a matching method for a heat accumulating type electric heating load and a power distribution network court. The method comprises the following steps of 1, establishing a minimum heat load demand calculation model of a user in each time period, and screening and determining a possible start-stop strategy of user equipment by combining a start-stop control strategy of heataccumulating type electric heating equipment and a heat accumulating amount calculation model of a heat accumulating electric heating heat storage tank in each time period; and 2, establishing a heataccumulating type electric heating load response optimization model aiming at stabilizing a total load curve of the power distribution network court and reducing the peak-valley difference, and searching an optimal start-stop control strategy as a matching method of the heat accumulating type electric heating load and the power distribution network court based on the screened and determined possible start-stop strategy of the user equipment in the step 1. According to the method, the interaction mode between heat accumulating type electric heating and a power distribution network can be improved through a direct load control manner, so that the advantages of the heat accumulating technology can be brought into full play and the heat accumulating type electric heating equipment can be popularized and used in a large range.

Description

technical field [0001] The invention belongs to the technical field of power system energy storage load participating in peak shaving and valley filling, and relates to an optimal matching method for heat storage electric heating load and distribution network platform load, in particular to a heat storage electric heating load and distribution network platform District matching method and system. Background technique [0002] In northern China, traditional heating generally adopts coal-fired methods. Due to the increasingly serious problem of energy shortage and air pollution, the country vigorously promotes green and energy-saving energy consumption patterns. As a clean and comfortable heating method, electric heating not only improves the atmospheric environment, but also improves the living standards of residents. With the development of "replacing coal with electricity", the heating load occupies a large proportion of the user load. The user's demand for heat is trans...
