Power grid power consumption load-based power supply automatic control method of virtual power plant

Abstract

The invention relates to a power supply capacity and power grid load-based automatic control method of a virtual power plant. With the method adopted, defects in the prior art can be eliminated. According to the technical schemes of the invention, the virtual power plant includes power generation units, power consumption units, a dispatching center station and a local data acquisition device; the local data acquisition device is in communication connection with the power consumption units and the power generation units; the local data acquisition device is in communication connection with the dispatching center station; the power generation units and the power consumption units are both connected with a power grid through controllable interfaces; and the controllable interfaces are connected with the dispatching center station. The method is characterized in that the power generation units may include power generator sets and / or energy storage devices; each energy storage device is at least connected with one power generator set; each power generator set is connected with the corresponding energy storage device through one controllable interface; a plurality of switchable units are configured in the virtual power plant; and the switchable unit comprises a switching unit energy storage device and a switching connection port.

Description

technical field [0001] This patent relates to the field of power grid regulation and control, in particular to a method for automatically regulating the power supply of a virtual power plant according to the power load of the power grid. Background technique [0002] With the increasing demand for electricity and the increasingly serious problems of energy shortage and environmental pollution worldwide, the disadvantages of traditional energy power generation have become increasingly prominent. Under the concept of Global Energy Internet, strategic constructions such as "One Belt, One Road" and "One Pole, One Road" are all committed to solving energy problems. Due to the high cleanliness of wind energy and solar energy and the low cost of power generation, renewable energy has become the main direction of global energy development in the future. With the advancement of the construction of the global energy Internet, the development of renewable energy will usher in a major ...
