Abstract

The invention provides a virtual substation scheduling method and terminal equipment. The method comprises the following steps: determining an electrical load of a target area according to a preset electrical load curve; detecting whether the electrical load of the target area is greater than the current power supply level of the microgrid of the target area, and detecting whether the electrical load of the target area is greater than the current power supply level of the microgrid group of the target area if the electrical load of the target area is greater than the current power supply levelof the microgrid of the target area; detecting whether the electrical load of the target area is greater than the power supply level of a virtual substation of the target area if the electrical loadof the target area is greater than the current power supply level of the microgrid group of the target area; and purchasing power from the total power grid through the virtual transformer substation to meet the electrical load of the target area if the electrical load of the target area is greater than the current power supply level of the virtual transformer substation of the target area. The virtual substation scheduling method and the terminal equipment can realize reasonable scheduling of distributed energy.

Description

technical field [0001] The invention belongs to the technical field of energy scheduling, and more specifically relates to a virtual substation scheduling method and terminal equipment. Background technique [0002] New energy in rural areas has the characteristics of various types, large quantities, and geographical dispersion. With the continuous increase in the number of distributed power sources, the power generation capacity of new energy sources is also increasing, and the problem of efficient utilization and consumption of clean energy in rural areas has become increasingly prominent. Restricted by natural conditions, distributed energy generation has great randomness and uncertainty. When a large number of distributed energy sources are connected to the grid, it will have a great impact on the stability and economic operation of the grid. For this reason, in the process of optimal dispatching of distributed power, fully considering the uncertainty of distributed pow...
