The three parts together complete the intelligent control of the energy station 2.
In the stage of collecting the load (energy supply demand data) of the user terminals 4 and uploading the load to the cloud platform 1, each user terminal 4 is provided with a corresponding heat exchange station 3, and heat is provided for the user terminals 4 through heat exchange between a water supply and return pipe network and the user terminals 4.

And when the energy station 2 does not receive the cloud-level monitoring platform instruction within a certain time, judging that the cloud platform 1 breaks down. At this time, the operating system in each energy station 2 is switched to the standby cloud platform 1.
And the energy station 2 inquires the energy supply table according to the energy supply instruction to determine an energy supply strategy stage, and after each energy station 2 receives the energy supply instruction of the cloud end, the energy station 2 determines the energy supply strategy to supply energy according to the energy supply table of the energy station 2.
To facilitate an understanding of the invention, the description is made in the specific context: the regional energy supply system comprises a plurality of energy forms, and for example, a regional energy supply system is configured nearby according to the distribution situation of available resource amount around each energy station 2. Firstly, explaining the energy supply of different energy supply modules, wherein the heat supply of the regenerated water source heat pump system module is 2.0 MW; the heat supply of the natural gas triple-generation system module is 1.2 MW; the heat supply of the ice storage system module is 0 MW; the heat supply of the ground source heat pump system module is 16.8 MW; the heat supply of the water chiller module is 0 MW; the municipal heat source module supplies heat for 8.7 MW. The invention takes heat supply as an example, so the cold supply is not taken as an example.
After each energy station 2 receives the cloud-side energy supply command, each energy station 2 determines an energy supply strategy by comparing its own energy station 2 energy supply table, for example, one energy supply table shown in table 1,
table 11 energy station winter energy supply dictionary table
Referring to table 1, the energy supply module of the energy station 2 comprises one or two groups of regenerated water source heat pump system modules and two groups of natural gas triple supply system modules, and if the energy supply requirement is less than 3MW, the energy supply module comprises one group of regenerated water source heat pump system modules and an external network energy storage module; when the energy supply range is 3-5MW, a regenerated water source heat pump system module is added. Here, the energy storage of outer net is for supplying cold and heat through water energy storage form, and in the energy supply unit ratio of No. 1 energy station 2 winter heat supply, all need to supply heat through water energy storage form in the energy supply scope, no longer gives details. If the energy supply range is 5-9MW, the energy is supplied by the ground source heat pump system module, and the energy supply module is 0.5 of the ground source heat pump system module (the ground source heat pump system module can realize 50% -100% energy supply, and 0.5 is the ground source heat pump system module which is opened arbitrarily); when the energy supply range is 9-11MW, the energy supply module adds a group of regenerated water source heat pump system modules for the ground source heat pump system module 0.5; when the energy supply range is 11-13MW, a group of regenerated water source heat pump system modules are added; when the energy supply range is 13-17MW, the energy supply module only comprises a group of ground source heat pump system modules, and when the energy supply range is 17-19MW and 19-21MW, a group of regenerated water source heat pump system modules are sequentially added; when the energy supply range is 21-22MW, the energy supply module is composed of a group of regenerated water source heat pump system modules, two groups of regenerated water source heat pump system modules and a group of natural gas triple co-generation system modules. Therefore, when the energy supply of the single energy supply module cannot meet the load requirement of the cloud platform 1, the remaining energy supply units are started successively. The energy supply range is 22-23MW, and the energy supply module comprises a group of regenerated water source heat pump system modules, two groups of regenerated water source heat pump system modules and two groups of natural gas triple co-generation system modules.
When selecting the energy supply module, because the liquid ratio friction drag can be ignored in the outdoor pipe network energy supply transportation process, only consider the cost between the different energy supply units this moment. When the energy supply module in a single form is used for supplying energy, the energy supply unit gradually rises to high load operation along with the increase of the load, the efficiency of the energy supply module is reduced to a certain degree at the moment, and the energy supply cost is increased. Therefore, in this process, the cost of the energy supply module being used is periodically compared with the cost of the power supply module not being used.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
