Output value of energy storage power stations

What is the energy storage system?

The energy storage system includes 1×5 MW×2 h LiB, 1×2 MW×2 h VRFB. And the wind power of 99 MW had been put into operation in August 2012. The system is connected with the 35 kV bus. Through intelligent control, the system stores and releases power according to the coordinating with wind power.

How many kW is a solar energy storage system?

The wind power is 2×780 kW, the PV power is 300 kW. The energy storage system includes 1×2 MW×2 h PbAB, 1×500 kW×15 s SCES and 5×500 kW bidirectional converters. The system can realize the flexible shift between on-grid and off-grid operation. This bidirectional balance can guarantee the island's power utilization.

How much subsidy should PV energy storage facilities be paid?

It specifies that energy storage facilities constructed synchronously with newly installed PV power generation should be paid a subsidy within 600 euro. In addition, the subsidy paid to energy storage facilities added to existing PV power generation should be within 660 euro/kW. What's more, price policies for PSS are relatively perfect in the EU.

How do you value energy storage?

Valuing energy storage is often a complex endeavor that must consider different polices, market structures, incentives, and value streams, which can vary significantly across locations. In addition, the economic benefits of an ESS highly depend on its operational characteristics and physical capabilities.

What is the construction capacity of a solar power station?

The construction capacity is 20 MW/40 MW h. The station is composed by 59000 batteries of 220ah and 128 PCS of 160 kW. The designed lifetime is 20 years. Users in industrial park can regulate their electric load autonomously. The system can smooth PV generation, and level peak-valley electric quantity.

What was the growth rate of energy storage industry in 2015?

Driven by the Euramerican and Asia-Pacific market, worldwide energy storage industry experienced fast development in 2015. According to CNESA, global cumulative installed capacity of energy storage system was 946.8 MW (excluding PSS, CAES and heat storage) by the end of 2015 and the growth rate was 12.7% compared with year 2014.
