Performance assessment of grid-forming and grid-following converter-interfaced battery energy storage systems on frequency regulation
3.3. Sensitivity analysis We conducted a sensitivity analysis of the system frequency response with respect to the critical converter control parameters. Two critical controls parameters that have a major impact on the control of the converters are studied: the p-f droop coefficient (f-p control gain) and the cut-off frequency of the low-pass filter.

The new economics of energy storage | McKinsey
Our research shows considerable near-term potential for stationary energy storage. One reason for this is that costs are falling and could be $200 per kilowatt-hour in 2020, half today''s price, and $160 per kilowatt-hour or less in 2025. Another is that identifying the most economical projects and highest-potential customers for storage has
