Abstract

Abstract:

In the context of pursuing dual carbon target and constructing a new power system with new energy as the main body， the virtual power plant has become an important component of smart grid and Energy Internet due to its flexibility and effectiveness in managing distributed energy resources. The virtual power plant integrates distributed energy resources （including adjustable load，interruptible load and energy storage）through controlling，metering，communication and optimization technologies，and realizes smooth interactions and optimized operation of source，network，load and storage，which is conducive to the rational and optimal allocation and utilization of resources. The structure，network topology，control strategy and key technologies of the virtual power plant accessed to the power dispatching system are introduced，and the problems in protection configuration，information communication and intelligent terminals are discussed.The improvement measures put forward provide a reference for similar projects.

Key words: virtual power plant, network topology, server, security zone, control strategy, energy storage, intelligent terminal, carbon neutrality, new power system, Energy Internet
