CONCEPT DEFINITION

What is a Microgrid?

A microgrid is a self-sufficient energy system that serves a discrete geographic footprint, such as a factory, island, mine, or community. Unlike traditional power relying on a distant central grid, a microgrid generates, stores, and manages electricity locally to ensure Energy Autonomy. It acts as a single controllable entity that can operate connected to the grid or break off and stand alone in Off-Grid Mode (Island Mode).

Energy Autonomy

Capable of operating independently from the national grid during outages.

Local Integration

Combines distributed generators (Solar/Diesel), batteries, and loads in one place.

Smart Control

Intelligent management software balances supply and demand milliseconds.

microgrid DESIGN PHILOSOPHY

PV-Primary, Multi-Source Synergy

The core objective of the EMS is Fuel Efficiency Maximization. By treating the Energy Storage System as an electronic buffer, we ensure diesel generators operate only when necessary and always at peak efficiency.

PV (Solar Generation)

PRIMARY SOURCE

Serves as the main energy provider for the base load, minimizing the reliance on fossil fuels during daylight hours.

BESS (Battery Storage)

BUFFER & STABILIZER

Acts as an “Electronic Voltage Stabilizer.” It absorbs instantaneous power fluctuations and captures reverse power flows, ensuring smooth system operation.

DG (Diesel Generator Backup)

ULTIMATE BACKUP

Provides voltage and frequency reference (V/f) and support during long-term deficits. Active units are minimized to save fuel.

Intelligent Operation Scenarios

Automatic mode switching based on real-time grid status.

Daytime: Renewable Optimization

CONDITION: HIGH SOLAR GENERATION

  • Zero Curtailment:If Solar Output > Load, the EMS directs excess energy to charge the battery, prioritizing free renewable energy to offset diesel consumption.
  • Power Smoothing: When clouds cause sudden solar drops, the ESS discharges instantly to fill the gap, allowing generators to ramp up slowly without strain.
  • DG Optimization:Redundant generators are shut down, keeping only the minimum required units running efficiently to achieve maximum Fuel Saving.

Impact Load: Motor Starting

CONDITION: HEAVY MACHINERY STARTUP

  • Peak Shaving: The ESS supplies the massive instantaneous current surge required by heavy motors (e.g., Mining Crushers), preventing generator stall-outs and protecting crankshafts.
  • Inertia Support: The system activates Virtual Synchronous Generator (VSG) technology to simulate mechanical inertia, ensuring Grid Stability during sudden load changes.
  • Voltage Stabilization: Reactive power is injected instantly to prevent voltage dips on the busbar, ensuring the Seamless Operation of sensitive onsite electronics.

Critical Safety: Reverse Power Protection

CONDITION: SUDDEN LOAD TRIP

  • Immediate Absorption: During sudden load rejection events, the BESS responds in milliseconds, instantly switching to charge mode to absorb excess active power.
  • Preventing Damage: This critical function prevents Reverse Power flow back into the diesel generators, eliminating the risk of catastrophic engine failure and costly downtime.
  • Emergency Regulation: If battery capacity is full, the EMS utilizes Frequency-Watt Control to rapidly curtail solar output, ensuring total system stability without tripping.

Night & Low Load Optimization

LOW CONSUMPTION / CAMP NIGHT LOAD

  • Preventing Wet Stacking: Running diesels at low load (<30%) causes harmful carbon buildup. The EMS automatically loads the generator (by charging batteries) to maintain optimal combustion, extending Engine Life and reducing maintenance.
  • Silent Operations: For accommodation camps, the system shuts down noisy generators at night. The BESS supplies power for AC and lighting alone, achieving Zero Noise for worker rest and 100% Fuel Savings overnight.
