Energy storage project construction cooperation

What is a compressed air energy storage project?

A compressed air energy storage (CAES) project in Hubei, China, has come online, with 300MW/1,500MWh of capacity. The 5-hour duration project, called Hubei Yingchang, was built in two years with a total investment of CNY1.95 billion (US$270 million) and uses abandoned salt mines in the Yingcheng area of Hubei, China’s sixth-most populous province.

What is a new energy cooperation framework for energy storage and prosumers?

A novel energy cooperation framework for energy storage and prosumers is proposed. A bi-level energy trading model considering the network constraints is presented. A profit-sharing mechanism is designed with the asymmetric Nash bargaining model. The adaptive alternating direction method of multipliers is applied efficiently.

How does the energy cooperation platform work?

The energy cooperation platform only reports the equivalent load p i, t c p of bus i to DSO. In the upper level, DSO checks the network operation according to the optimal power profiles from the lower level.

What is the proposed energy cooperation problem?

The proposed energy cooperation problem requires minimizing the social energy costs, which includes all the individual energy costs of prosumers and CESSs. The energy cooperation problem is stated as: (21) min ∑ n ∈ N C n p + ∑ n ∈ N τ n p + ∑ m ∈ M C m c + ∑ m ∈ M τ m c

Can a new energy cooperation framework improve the energy economy?

A novel energy cooperation framework for CESSs and prosumers is proposed with an energy cooperation platform as an intermediary, improving the energy economy and solution efficiency.

What is a two-stage model for energy storage sharing?

For example, formulated a two-stage model for energy storage sharing between CESSs and prosumers, where CESSs decide the price of virtual storage capacity in the first stage and prosumers decide the capacities and charging/discharging power in the second stage.
