Under the background of energy Internet, the power grid in China is witnessing an increasing penetration level of renewable energy power generation and the AC/DC ultra-high voltage (UHV) interconnection between regional power grids, which increases greatly the system reserve requirement for contingency and system power fluctuation. At the same time, reserve sources from demand side and energy storage will become important complement to conventional generators. The current management mode of ancillary service categorization and management based on "two rules" can hardly satisfy management requirements of future power grid reserve services. In this respect, a new reserve categorization system is proposed for the energy internet from the perspective of controlling process. The response time and duration requirements are specified. The new reserve categorization system is compatible with diversified reserve sources from generators, networks, loads, and energy storage. The types of reserve services they can provide are also discussed. The corresponding market-oriented reserve configuration suggestions and related problems to implement the new reserve system are put forward.

Key words: reserve system, energy Internet, renewable energy system, energy storage reserve, demand-side reserve, market-based reserve
