Define the battery service and SOC basis, calculate lull deficits, check diversion limits and retain chronological shortages, recovery and operating evidence.
State whether storage covers essential loads, smooths a supply profile or supports an independent system. Record required service duration, fallback actions, actual load schedules and simultaneous power needs. Place wind, optional PV and load on one DC-bus basis after their stated conversion paths.
Collect the battery/BMS manual, approved arrangement and actual capacity under temperature, age and discharge conditions. Record charging, discharging, voltage and SOC limits with separate efficiency paths. Distinguish available capacity from nominal capacity and verify that the rest of the system accepts the battery envelope.
Build a documented sequence of loads and expected wind/PV during the lull. Sum only positive bus deficits and account for discharge losses, the actual starting-to-minimum SOC window and available-capacity fraction. Keep short peak power and battery arrangement checks separate from this energy estimate.
Obtain maximum current from every source that the diversion controller must handle and its exact required allowance. Check load resistance at actual regulation voltages, per-element installed heat/voltage limits and the controller maximum current. Retain any infeasible range and resolve it through a documented equipment revision.
Run the actual interval order with charging and discharging limits, conversion losses and the initial SOC. Inspect final stored energy, unmet load, curtailed PV and required/handled/unhandled wind diversion. Compare capacity and control alternatives using the same sequence and include realistic resource shortages.
Commission the accepted battery/control arrangement through the exact qualified procedure and preserve settings, test results and unresolved items. Track source, load, SOC, temperature and charge-throughput records over time. Revise available-capacity and service assumptions from evidence, saving comparable cases and exportable plans.
Prepare a lull case and chronological common-bus profile. · Enter available capacity and bus-power limits in the chronological mode. · Calculate nominal Wh for the supplied lull without an assumed half-load wind contribution. · Track chronological SOC and an exact energy-conservation account. · Save measured sequence revisions using their actual starting state and equipment limits.
Record the starting and limiting SOC with a named capacity basis. · Retain the SOC window and throughput reference without treating throughput as remaining battery life. · Reconcile the retained SOC and throughput records after a profile run. · Keep consistent SOC and cumulative throughput comparisons.
Inspect a separate PV load/recharge case when solar is part of the service plan.
Calculate voltage-dependent element heat and feasible parallel counts under distinct minimum/maximum constraints.
Retain the turbine’s actual threshold and control envelope with the storage proposal.

Check minimum source absorption separately from maximum permitted controller and element loading.
Time order matters for storage; distribution energy alone cannot establish service reliability.
Battery integration belongs to the complete equipment and operating plan.
Nominal Wh, available Wh, stored Wh and bus-delivered Wh differ once conditions and conversion losses are applied.
Use the same profile to compare capacity or power limits before changing the weather and load cases.
