The 33rd China International Exhibition on Electric Power Equipment and Technology
Shanghai International Energy Storage Technology Application Expo / Hydrogen Energy Expo
A Virtual Power Plant (VPP) is a software-defined energy management system that aggregates and coordinates a portfolio of distributed energy resources (DERs) — including rooftop solar, battery storage, electric vehicle chargers, and controllable industrial loads — to operate collectively as a single, dispatchable generation and demand management resource. Unlike a physical power plant, a VPP has no single location; it exists as a digital layer connecting thousands of distributed assets through communication networks and optimisation algorithms. VPPs enable grid operators to dispatch distributed resources for frequency regulation, peak shaving, voltage support, and renewable energy integration. In China, VPP pilots are underway in Shanghai, Guangdong, and other provinces as part of the smart grid and new power system development strategy.
5 Key Questions About Virtual Power Plant (VPP)
A microgrid is a physically localised energy system — typically serving a campus, industrial park, or community — that can operate in isolation from the main grid. A VPP, by contrast, is a geographically dispersed collection of resources connected only through digital communication, with no physical boundary. A microgrid prioritises local energy independence and resilience, while a VPP prioritises grid services and market participation. A microgrid may participate in a VPP as one of its aggregated resources.
VPPs can aggregate any controllable distributed energy resource including: rooftop solar PV systems; residential and commercial battery storage; electric vehicle chargers and vehicle-to-grid (V2G) systems; industrial flexible loads (HVAC, refrigeration, pumping, EAF steel furnaces); backup generators; small wind turbines; and demand response programmes. The common requirement is that each resource must be remotely controllable and metered in real time through a communication interface.
VPPs can provide a wide range of grid services: frequency regulation (responding within seconds to frequency deviations by adjusting generation or load); peak demand reduction (reducing consumption during system peak hours); voltage support (reactive power management at distribution level); renewable energy integration (absorbing surplus solar or wind generation into storage); capacity market participation (committing to provide generation or demand reduction when called upon); and energy arbitrage (charging storage when electricity is cheap and discharging when prices are high).
A VPP requires a cloud-based aggregation platform with optimisation algorithms; smart meters or IoT controllers at each resource site providing real-time measurement and remote control capability; reliable communication networks (broadband internet, 4G/5G, or dedicated communication channels); and interfaces to grid operator systems for receiving dispatch signals and reporting performance. Cybersecurity is critical given the VPP's role in controlling grid-connected assets. Standards including OpenADR (for demand response), IEEE 2030.5 (for DER communication), and IEC 61850 (for substation integration) provide interoperability frameworks.
China's National Energy Administration has issued pilot VPP policies in several provinces, and the 2021 'New Power System' policy framework explicitly supports VPP development as a key flexibility resource. Shanghai launched China's first commercial VPP in 2017, and Guangdong, Jiangsu, and Zhejiang have followed with their own pilot programmes. The development of electricity spot markets in China is creating the price signals needed for VPP economic viability. Regulatory frameworks for VPP market participation, metering, and settlement are still evolving.
