Embodiment 1

[0036] This embodiment discloses an automatic control device for optimal operation of a heat storage electric heating system based on a day-ahead electricity price and a corresponding control method. see figure 1 , the automatic control device is located at figure 1 to the left of the , the controls are located on the figure 1 The main working principle of the thermal storage electric heating device on the right is: according to the predicted value of the 24-hour hourly heating load and the predicted value of the time-of-use electricity price in the next natural day, choose to control the thermal storage electric heating device during the low electricity price period when the electricity price is low. The heating device heats at full power and stores excess heat in the heat storage body. During the period of high electricity price, the heat storage body supplies heat, and judges the remaining heat storage and heating time in real time, and selects the auxiliary electric heati...

Abstract

The invention belongs to the technical field of electric heating and discloses a device and method for automatically controlling optimized operation of a heat accumulating type electric heating systembased on the current electricity price. The device comprises a communication module, a data storage unit and a data processing unit. The communication module is used for receiving relevant heating data and obtaining environment temperature prediction data and time-of-use electricity price prediction data. The data processing unit is used for calculating the hourly heat supply load prediction value according to the data received by the communication module, the remaining heat supply duration of a heat accumulator and the optimal starting moment and duration of electric heating and giving out starting instructions to an electric heating system at the moment. The data processing unit is used for storing relevant data. By means of the device and the method, the actual heating capacity of theheat accumulating type electric heating system can be known, and the starting time and stopping time of electric heating can be arranged reasonably and conveniently.

Description

technical field [0001] The invention relates to an automatic control device and method for optimal operation of a heat storage electric heating system based on a day-ahead electricity price, and belongs to the technical field of electric heating. Background technique [0002] With the continuous promotion of electric energy substitution in the northern region, electric heating instead of traditional coal-fired heating gradually occupies more and more market shares. Among them, the regenerative electric heating system can fully Utilize the low electricity price at night, collect and store the low-priced heat energy at night, and transfer it to the peak electricity price period during the day, thereby reducing the operating cost of users in the heating season. [0003] Regenerative electric heating system can be divided into: solid heat storage type, water heat storage type, phase change heat storage type and other types according to the different heat storage body materials. ...
