Distribution feeder DER hosting-capacity assessment report

DER connection can be simulated at a single point, but there is no systematic assessment of the maximum PV / storage capacity that a whole feeder can host.

Built-in chapter list (from the specification)The specification asks for 8 chapter(s); the engine can produce 1 of them for this report.
Standards basisIEEE 1547; technical rules for connecting distributed generation to distribution networks; international utility practice for hosting-capacity assessment.
⚠ The specification switch `studyOptions.enableFeederHostingCapacityReport` is NOT wired. Feeder DER hosting capacity exists under `enableHostingCapacity` (`engines/hosting-capacity.js`, chapter `hosting-capacity`).

Built-in chapter list (from the specification)8 chapter(s)
  1. 1.Report overview: feeder topology, load profile, constraints (voltage, ampacity, short circuit, power quality), standards applied.
  2. 2.Feeder base parameters: line impedance, short-circuit capacity, existing load distribution.
  3. 3.DER connection constraint-boundary analysis: voltage limit, branch overload, short-circuit capacity exceedance, harmonic constraints.
  4. 4.Maximum feeder hosting capacity: permissible DER capacity for the whole feeder and for different connection locations.
  5. 5.Multi-scheme simulation comparison: hosting capacity versus connection location and storage configuration.
  6. 6.Limit-violation risk summary: weak nodes caused by high DER penetration.
  7. 7.Capacity-upgrade recommendations: larger conductor cross-section, added reactive compensation, voltage-regulating devices to raise hosting capacity.
  8. 8.Appendix: simulated cases, constraint limits, parameter list.

Explicitly out of scope (from the specification)4
  • · Quasi-steady-state batch simulation; no long random time-series probabilistic assessment.
  • · No dynamic adjustment of protection settings as DER penetration changes.
  • · No probabilistic hosting capacity under long-term random weather variation.
  • · Engineering estimates only; actual grid connection still requires utility review.
