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.
This paper systematically studies the energy management system (EMS) of M-GES plants. We establish a general M-GES state-of-charge model for the first time and propose the maximum height difference control (MHC) for EMS. To validate the effectiveness of the MHC, we use sinusoidal test power and a natural California load …

All these cases have been computed over the full year of 2016 with a starting SOC of 50% of the energy capacity. Fig. 3 shows the added revenue over the full year for each of the cases as compared to operate the …
