Demand-response curtailment of a charge plan: curtailed energy sign · case 05

Curtailment reports a negative reduction.

Member previewVariant 5 · 3 implementations · 7 checks per implementation

Case contract

profile is planned watts per slot. events are [start, end, pct, opt_out]; during [start, end) a non-opted-out event limits power to pct percent of plan (integer floor of p*pct/100), and overlapping events apply the lowest pct. Curtailed power never drops below min(plan, floor_w). Return [new profile, total curtailed watts over slots].

Why this case matters

Depot, workplace and public EV chargers schedule sessions against prices, circuit limits and departure deadlines; a wrong decision silently strands a driver or overloads a feeder.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
boundary: event ends at slot	`[[1840, 3680, 3680], -1840]`	`[[1840, 3680, 3680], 1840]`	Failed
