3. Operation strategy. The operation strategy consists of three separate parts: (1) forecasting of wind velocity, (2) scheduling of the power exchange with the market and, (3) on-line operation of the storage. In the present model, the forecasts of load and spot price are assumed to have 100% accuracy.
In this work, we divide ESS technologies into five categories, including mechanical, thermal, electrochemical, electrical, and chemical.
