What is a Virtual Power Plant (VPP)?
A Virtual Power Plant (VPP) is a cloud-based distributed energy platform that aggregates and coordinates a large number of dispersed energy resources—such as distributed photovoltaic panels, wind power, energy storage systems, electric vehicle charging piles, flexible loads, and backup generators—through advanced software, communication, and control technologies.
It operates and dispatches these scattered resources as a single unified power system on the grid side, just like a conventional centralized power plant, but without building actual physical power generation facilities.
Functions and Roles of a Virtual Power Plant
Peak Shaving and Valley Filling
It stores or generates power during low-demand periods and releases power during peak electricity consumption, easing grid pressure and reducing the risk of power shortages.
Grid Stability and Frequency Regulation
It quickly responds to grid fluctuations, adjusts real-time power output, maintains frequency and voltage stability, and improves the safety and reliability of the power system.
Consumption of Renewable Energy It effectively absorbs wind and solar power, reduces curtailment of renewable energy, and supports the low-carbon transition of the energy system.
Demand Response Optimization
It regulates user-side flexible loads to match power supply and demand, lowering overall electricity costs for users and the grid.
Market Participation
It participates in electricity spot markets, capacity markets, and ancillary service markets, enabling distributed energy resources to gain economic benefits while improving overall energy efficiency.
Decentralized Energy Management
It replaces part of the investment in large thermal power plants and transmission infrastructure, promoting a more distributed, intelligent, and low-carbon power grid.
