Virtual Power Plant: Virtual Power Plant, VPP for short.
DG: distributed generator, distributed power supply.
DER: distributed energy resource, distributed energy resource. DER includes DG, and DG belongs to a kind of DER. DER includes power supply, load, and so on.
Virtual power plant is relative to physical power plant, objectively it does not exist. It solves the problem of instantaneous balance of power generation, power supply and power consumption by aggregating the resources of all parties, including power generation, power consumption and energy storage, and deploying the actions of all parties based on big data forecasts.
The power generation side can basically be deployed, for example, to let a certain PV power plant to generate more or less power, has to meet the load side of the sudden increase or decrease.
Because photovoltaic power generation has light requirements, what if there is a need to generate more power when there is not enough light? The energy storage system can be used as a complementary measure, that is, when there is sufficient light, the electricity issued will be stored, and then taken when used. Wind power, tidal power, etc. have a similar problem.
The only load side that seems to be able to be deployed is for EVs that aren't in a hurry to charge at night, so as long as they are guaranteed to be fully charged at 7am and don't delay their owners from going to work, they can get rid of the load the rest of the time.
The first thing that comes to mind is to analogize virtual power plants to intermediaries, doing the job of keeping the matchmaker pulling the strings. Matchmakers understand the market situation, for example, that who's little who has no daughter-in-law, just next door to the village of Wang's daughter is not married, then find both parents to talk to the two young people to together a handful of summary. Only the virtual power plant these operations are automated, the operation includes the collection of information from all parties, to give orders to all parties. But then I saw a better analogy on the Internet, the energy sector of the drop, for the taxi people and drivers to provide a release of information, to reach a deal, and to provide auxiliary services of the platform.
Once again, I realized the truth: information, resources, and connections are money.
