Results Dictionary

The solve_ots() function returns a dictionary with the following keys:

Optimization Status

:z - Line switching decisions [D × risky_lines] (1=energized, 0=de-energized)
:va - Voltage angles [D × T × buses] (radians)
:p - Real power flows [D × T × branches] (MW)
:g or :pg - Real power generation [D × T × generators] (MW)
:load_shedding or :p_load_shedding - Load shedding [D × T × buses] (MW)

LACOTS only:

:total_load_shed - Total load shedding across all periods (MW)
:total_risk - Total possible wildfire risk (baseline)
:active_risk - Wildfire risk from energized lines (accounts for hardening if enabled)
:removed_risk - Wildfire risk eliminated by switching
:risk_reduction_pct - Percentage of risk removed
:switched_off_lines - Dict mapping day index to list of de-energized line IDs

Hardening Results (if hardening enabled):

:y - Line hardening decisions [hardenable_lines] (1=hardened, 0=not hardened)
:hardened_lines - Vector of hardened line IDs
:hardening_cost - Total hardening cost in USD
:mitigated_risk - Wildfire risk mitigated by hardening

Battery Results (if battery enabled):

:x - Battery capacity decisions [battery_locs] (p.u., where 1 p.u. = 100 MWh)
:soc - State of charge [D × (0:T) × battery_locs] (p.u.)
:p_charge - Active power charging [D × T × battery_locs] (p.u.)
:p_discharge - Active power discharging [D × T × battery_locs] (p.u.)
:q_charge - Reactive power charging (LACOTS only, p.u.)
:q_discharge - Reactive power discharging (LACOTS only, p.u.)
:batteries_installed - Vector of bus IDs with installed capacity ≥ 0.01 p.u.
:total_battery_capacity - Sum of all installed capacity (p.u.)
:battery_cost - Total battery installation cost in USD

Solar Results (if solar enabled):

:s - Solar capacity decisions [solar_locs] (p.u., where 1 p.u. = 100 MW)
:p_solar - Active power generation [D × T × solar_locs] (p.u.)
:q_solar - Reactive power injection (LACOTS only, p.u., bidirectional)
:solar_installed - Vector of bus IDs with installed capacity ≥ 0.01 p.u.
:total_solar_capacity - Sum of all installed capacity (p.u.)
:solar_cost - Total solar installation cost in USD
:total_solar_generation - Total active power generated (p.u.·h)
:total_solar_q_injection - Total reactive power injected (LACOTS only, p.u.·h)

Notes:

For the thresholded method, :z values are pre-computed fixed scalars (0 or 1), not optimization variables
:y values are always binary optimization variables when hardening is enabled, regardless of switching method
When hardening is enabled, :active_risk accounts for risk reduction from hardened lines
Battery capacity :x[n] is a continuous variable (p.u.); buses with capacity < 0.01 p.u. are considered uninstalled
Solar capacity :s[n] is a continuous variable (p.u.); buses with capacity < 0.01 p.u. are considered uninstalled

verify_ac() returns a dictionary organized by (day, hour):

:status - Dict mapping (d, t) to the nonlinear solver termination status
:feasible - Dict mapping (d, t) to a Boolean feasibility flag
:feasible_all - true if every checked hour solved to a feasible point
:failed_hours - Vector of (d, t) pairs that did not solve feasibly
:hours - Per-hour detailed results with bus voltages, generator dispatch, branch flows, load shed, and fixed branch statuses
:total_p_load_shed - Total active load shed across all checked hours
:total_q_load_shed - Total reactive load shed across all checked hours
:total_load_shed - Alias for total active load shed

Each results[:hours][(d,t)] includes:
