Economic operation of wind power and energy storage

How does energy storage work in a wind farm?

After energy storage is integrated into the wind farm, one part of the wind power generation is sold to the grid directly, and the other part is purchased and stored with a low price, and then is sold with a high price through the energy storage system.

What is the operation strategy of a wind farm?

The operation strategy is that at off-peak time (low price), the energy storage system stores electricity; at on-peak time (high price), it releases electricity. Benefits are generated through the electricity price arbitrage. The revenue of generation from a wind farm without energy storage was calculated by equation (1) throughout a whole year.

How a wind-storage coupled system can increase the initial investment?

When integrating the energy storage plant, it stores the wind power when the electricity price is low, and releases it when the price is high. The total income of the wind-storage coupled system can be significantly increased. However, it will increase the initial investment by adding energy storage system.

How integrating energy storage technologies into wind generation improve economic performance?

The economic performance by integrating energy storage technologies into wind generation has to be analyzed for commercial development . One solution is to implement the electricity price arbitrage strategy. The real-time pricing (RTP) varies in the market throughout a single day due to the different patterns of supply and demand.
