Relying on information technology to coordinate the supply and demand sides, a new type of power dispatching is implemented to achieve peak shaving and valley filling.

Power dispatching is an ancient topic, and virtual power plants mainly strengthen the communication between the supply side and the demand side. Compared to previous supply-demand coordination, it strengthens the mechanism of active negotiation, including advance and real-time invitations or market transactions.

In terms of opportunities, on the one hand, there are more and more energy storage devices, in addition to infrastructure, the consumer-side reserve equipment such as new energy vehicles is increasing rapidly. On the other hand, there is the issue of "waste electricity" from clean energy, which does not have the flexible response capability like thermal power and hydropower. This leads to an increasing demand for power regulation and optimization space.

The video says that by 2050, the proportion of new energy generation will reach 60%, and by regulating new energy power plants alone, peak shaving and valley filling can be achieved effectively.

  • Peak shaving: Virtual power plants negotiate to reduce demand-side consumption or increase supply.
  • Valley filling: Virtual power plants negotiate to increase demand-side or reduce supply.

For example, on a certain night when there is excess power capacity, new energy vehicle owners are encouraged to charge and consume the excess power.
