Flexible AC Transmission TRIZ Cases
- Time-Synchronized Injection Modules for Low-Harmonic Power Flow Control
Distributed impedance injection modules coordinate phase-shifted pulses to smooth HV waveforms, cut harmonics, and improve power flow control.
- Hierarchical BESS Control for Coordinated Microgrid Peak Management
A multi-level BESS controller coordinates grid charging and battery discharge across adjacent microgrids to balance peak demand and avoid interruptions.
- Integrated STATCOM Energy Storage Using Dormant Converter Arms
Dormant STATCOM chain-links connect energy storage for active and reactive grid support while avoiding separate converter hardware.
- BESS Forecast Control for Renewable Curtailment and Battery Cycling
Forecast-driven BESS control cuts renewable curtailment, limits battery cycling, and maintains diesel generator timing in isolated microgrids.
- BESS Energy Offset Control for Parasitic Standby Losses
A secondary BESS and switch control keep plant devices powered during standby by offsetting parasitic losses without extra grid draw.
- Phase-Shifting Transformer With Shared Tapped Coils and Fewer OLTCs
Shared tapped coils let one PST handle voltage regulation and phase shifting with fewer OLTCs and a smaller magnetic circuit.
- BESS Energy Offset Control for Standby Parasitic Losses
When standby parasitic losses drain a BESS, redirected renewable power keeps plant equipment running and reduces grid dependence.
- BESS Access Control Using Gas Monitoring and Safety Recommendations
Gas, temperature, and occupancy sensing are combined to assess BESS entry safety and lock access during hazardous conditions.
- BESS Pre-Cooling Around Charge-Discharge Thermal Peaks
Pre-cooling a BESS before scheduled charging or discharging cuts thermal-control energy use and helps protect battery life.
- BESS Black-Start Voltage Ramping to Limit In-Rush Currents
Gradual bus-voltage ramping lets BESS units synchronize for black start while limiting transformer in-rush and circulating currents.
- Distributed Generator Inverters as STATCOMs for Grid Voltage Control
Idle or underused distributed generator inverters supply reactive power for voltage regulation and grid stability without added devices.
- Stacked Inverter-Transformer Skids for Space-Limited Energy Storage
Vertical, laterally offset inverter-transformer skids raise energy storage density in tight sites while preserving maintenance access and heat dissipation.
- Series Static Compensator With Fault-Current Limiting Transformer
A bypass-linked transformer and low-voltage inverter let coupled distribution networks isolate faults fast and prevent fault propagation.
- IIU Activation Sequencing for Balanced FACTS Electrical Stress
Rotating the activation order of impedance injection units equalizes electrical stress in TL-FACTS, improving reliability and service life.
