Battery Bank Calculations
(OP)
Is there a resource or standard practice for calculating the number and size of batteries for large UPS battery bank installations to accomplish desired ridethrough time, cycling requirements, voltage regulation, frequency regulation, etc.?

When dealing with the battery and/or UPS suppliers, be sure to fully disclose all of the conditions that need to be addressed. Battery chemistry and battery structure may be more important issues number of than the number of cells. Recharge rates may be an important issue, too.
Rather than limiting yourself to battery systems, you may want to seriously consider the latest flywheel based systems.
Standard practices provide nice guidelines for design considerations, but most large UPS applications involve specific combinations of needs and available facilities that will heavily influence design/selection decisions. The issues of initial cost, operating costs, maintenance costs, required service life, personnel skill/training requirements, etc. must all be properly taken into consideration.
