The obiective of this Draft Standard, hereafter referred to as the ‘Code, is to estabhsh uniform test methods and procedures forconducting performance tests of mechanical or thermal energy storage system(s) (ESS). An ESS is a system that consumes energy to increase the internal energy of the storage mecha and releases the stored energy. producing iselul power or heat. This Code provides standard test procedures for ESS with the goal to provide the highest level of accuracy consistent with current engineering practice.
This Code provides procedures for measuring the following parameters:
(a) the quantity of energy input
(b) the rate of energy input (power)
(c) the quantity of rionuseful energy flows in/out of the system during input, steady-state storage, and discharge
(d) the quantity of useful energy output
(e) the rate of useful energy output (power)
The Code provides quantifiable methods to assess the performance of mechanical or thermal energy storage systems for various technology platforms and applications.
When tests ars conducted in accordance with a code, the test results themselves, without adjustment for uncertainty, yield the best available indication of actual performance of the equipment tested within the operational parameters ilefined In this Performance Test Code (PTC). This Code does not specify means to compare those results to contractual guarantees. Therefore, it is recommended that parties to a commercial test agree on the method to be used for comparing results to commercial guarantees before starting the lest) It Is beyond the scope of this Code to determine or Interpret how such comparisons are made.
This Code is not to be used in troubleshooting equipment. However, this Code can be used to quantily the magnitudeof performance anomalies of equipment that is suspected lobe performing poorly orb confirm the need for maintenance, if simpler means are not adequate. This Code can be used as a source or reference for simpler routineor special equipment test procedures.
1-2 SCOPE
1-2.1 Types of Systems to Which This Code May AppLy
This Code applies to mechanical or thermal ESS including, but not limited to. compressed air, flywheel, molten salt, and pumped hydromechanlcai ESS and sensible, latent, cryogenic, thermochemical, ice-based, or phase-change-material thermal ESS.
ASME PTC 53 applIes to the measurement of the performance of an ESS at the specified conditions, with all equipment associated with the system functioning in accordance with those conditions.
An ESS may use any of various media, Including, but not limited to, the following:
(a) thermal energy storage media, such as phase-change media (e.g., liquefied air or water-ice) or sensible heating media (e.g., molten salt or thermal fluids and oils)
(b) compression media, such as compressed air or springs
(c gravitational media, such as pumped hydromechanical energy or railcars on Inclines
(d) chemical media, such as hydrogen or ammonia reactions
(e) kinetic media, such as flywheels
(f) electrolytic media, such as flow batteries
3-3 TEST PREPARATIONS
All parties to the test shall be given timely notication, as defned by prior agreement, to alw them the necessary time to respond and to prepare personnel, equipment, or documentation. Updated information should be provided as it becomes known.
A test log shallbe maintained during the test to record any occurrences afecting the test, the time of the occurrence, and the observed resultant effect. This log becomes part of the permanent record of the test.
The safety of personnel involved in the test should be considered; for example. the following should be provided:
(a) safe access to test point locations
(b) availability of suitable utilities
(0) safe work areas for personnel
In addition, care ofthe instrumentation involved in the test should be considered; there may be potential for calibration shifing or damage to instrumentation due to extreme amblent conditions such as temperature or vibration.
Documentation shall be developed or be made available for calculated or adjusted data to provide independent verification of algorithms, constants, scaling, callbration corrections, offsets, base points, and conversions.
3-3.1 Preparation
For acceptance tests, the manufacturer or supplier shall have reasonable opportunity to examine the equipment, correct defects, and render the equipment suitable to test. For other official tests, the manufacturer or supplier may, by request of the ESS owner, have reasonable opportunity to examine the equipment, correct defects, and render the equipment suitable to test. The manufacturer, however, is not thereby empowered to alter or adjust equipment
or conditions in such a way that regulations, contract, safety. or other stipulations are altered or voided. The manufacturer may not make adjustments to the equipment for test purposes that may prevent immediate, continuous, and reliable operation at all capadties or outputs under all speified operating conditions. Any actions taken shall be documented and immediately reported to all parties to the test.
