6 FAQs about [Dynamic profit analysis of energy storage power station]
How do business models of energy storage work?
Building upon both strands of work, we propose to characterize business models of energy storage as the combination of an application of storage with the revenue stream earned from the operation and the market role of the investor.
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.
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.
How can energy storage be profitable?
Where a profitable application of energy storage requires saving of costs or deferral of investments, direct mechanisms, such as subsidies and rebates, will be effective. For applications dependent on price arbitrage, the existence and access to variable market prices are essential.
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 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.
