Under the“double carbon”goal

the power supply subject of the new power system will gradually transform from fossil energy to renewable energy

which greatly increases the pressure on supply and demand for power systems. Virtual power plants can gather massive

decentralized

and diverse distributed resources through advanced regulatory technology to form a subject of flexible regulation

which provides a feasible path for ensuring the safe and reliable operation of the new power system. Firstly

the concepts and types of virtual power plant is introduced. Secondly

key technologies of existing virtual power plants are analyzed from four aspects：resource aggregation

cooperative control

optimized scheduling and commercial operation. Then typical project cases of virtual power plants at home and abroad are summarized. Finally

challenges faced by virtual power plants under the new power system are pointed out

and the development direction of virtual power plants under the new power system is expected from three aspects：external specific quantitative analysis

low-carbon aggregation regulation

and new commercial operations.
