Problems solved by technology

[0004] The traditional heat storage and release strategy is relatively simple. There is no reasonable control strategy and heat storage and discharge capacity calculation model for electric heat storage devices. It is easy to occur when the heat storage is insufficient, and the indoor temperature cannot be maintained, which affects user experience. There is no scientific and reasonable plan for the deployment of thermal stations, and the consideration is often relatively simple, ignoring investment costs, economic planning of operating costs, and factors of hydraulic balance of the heating network, which cannot meet the needs of combined heat and power dispatching of central heating systems

Description

technical field [0001] The invention belongs to the technical field of intelligent heating, and in particular relates to a planning method and system for an electric heat storage device based on hydraulic calculation and double-layer optimization. Background technique [0002] For a long time, coal-fired units have been the main source of heating for cities and towns in northern my country in winter, and the emissions of air pollutants such as carbon dioxide are large. Replacing the traditional coal-fired central heating is showing a rapid growth trend. Taking advantage of the low electricity price, collecting and storing low-priced heat energy, and then transferring it to the peak electricity price period can reduce the operating cost of electric heating. [0003] It is engineering feasibility to arrange electric heat storage devices in the heat station of the central heating system and use them complementary to the existing central heating system. Electric thermal storage ...
