Revenue Stacking for BESS: Fast Frequency Regulation and Balancing Market Participation in Italy

Algorithm 2

FR availability block selection.

	Input: Cumulative hourly frequency deviation with respect to 50 Hz in 2016 (ΔF2016)
	Output: Set of 100 availability blocks for FR provision (FRΔF), each one lasting for 10 hours
	CΔF: 10-hour cumulative frequency deviation blocks
	for t in ΔF2016 do
	Compute the 10-hour cumulative frequency deviation
	return 8774 blocks of 10-hour cumulative frequency deviation
	List the blocks in descending order: CΔF^t ⟶ CΔF^t↓
	FRΔF^1 ← CΔF^1↓, s = 2
	for c indo
	while s ≤ 100 do
	if CΔF^c↓ is not overlapping withdo
	FRΔF^s ← CΔF^c↓
	s ← s + 1
	return 100 availability blocks of 10-hour FRΔF
