Professor Liu Dunnan: Flexibility resources under the energy internet

1) Infrastructure

Build multi-energy coordinated integrated energy network facilities and promote the construction of integrated energy network infrastructure. At the same time, promote the construction of energy access transformation and coordinated regulation infrastructure.

2) Market environment

Build a market trading system to restore the market attributes of energy commodities; cultivate new market players; gradually build a diversified trading system with energy, ancillary services, new energy quotas, virtual energy currency, etc. as the subject matter; construct energy wholesale and retail trading markets in a layered manner to achieve flexible and equal energy sharing and trading anytime, anywhere; establish an Internet-based micro-balance market trading system to encourage small and micro users such as individuals, families, and distributed energy to flexibly and independently participate in the energy market.

3) Development model

First, develop new models for energy storage and electric vehicle applications. Develop a networked management and operation model for energy storage, integrate various types of distributed energy storage equipment and facilities, and build a database for energy storage facilities; build an energy storage cloud platform to support the free and flexible trading of energy; promote energy storage to provide value-added services such as energy leasing, emergency backup, peak load regulation, and frequency regulation. Develop a smart charging and discharging model that coordinates vehicles and the grid, and promote the two-way interaction of energy and information between electric vehicles and smart grids; give full play to the role of electric vehicles as off-peak loads, actively carry out smart charging and discharging services, and participate in power demand response.

Second, develop new models of smart energy use and value-added services. Build a new model of user-independent energy services. Gradually cultivate emerging market players such as virtual power plants, load integrators, and third-party value-added service providers to increase the supply of flexible resources; encourage users to independently provide flexible energy services such as energy response, frequency regulation, and peak regulation, and conduct dynamic and real-time transactions based on the Internet platform; further improve relevant market mechanisms, and be compatible with channels for users to autonomously participate in flexible resource market transactions in direct, indirect and other ways; establish a reasonable compensation pricing mechanism for flexible resources to ensure that flexible resource investments have reasonable returns.
