The Ecosense Microgrid Lab is a modular energy ecosystem that replicates the operation of real-world microgrids at laboratory scale. It allows users to generate energy, store energy, distribute power, manage loads, and control grid interaction through a centralized control and energy management framework.
The lab is built around four configurable layers:
- Multiple Energy Sources
- Multiple Energy Storage Systems
- Multiple Loads (AC & DC)
- Central Energy Management & Control System
Each layer can be independently configured and later expanded.
1. Multiple Energy Sources: The Microgrid Lab can integrate one or more of the following energy sources, depending on user requirements:
- Solar PV arrays or Solar PV Emulators
- Wind Energy Systems or Wind Turbine Emulators
- Fuel Cell systems (hydrogen-based generation)
- Diesel Generator or Grid Emulator
- Utility grid interface
Students can study:
- Renewable intermittency and variability
- Power sharing between sources
- Source prioritization strategies
- MPPT behavior and source dynamics
- Hybrid generation scenarios
Energy sources can feed common DC buses, AC buses, or hybrid AC–DC networks, depending on the microgrid architecture.
2. Multiple Energy Storage Systems: Energy storage is a critical element of microgrids. The lab supports multiple storage technologies, such as:
- Battery Energy Storage Systems (BESS)
- Ultracapacitors
- Hydrogen storage (via fuel cell systems)
- Hybrid storage combinations
Students can perform experiments on:
- Charging and discharging cycles
- State-of-charge (SoC) based dispatch
- Load leveling and peak shaving
- Backup power during outages
- Storage coordination in hybrid systems
The lab demonstrates how storage stabilizes microgrids and enables high renewable penetration.
3. Multiple Loads (AC & DC): The Microgrid Lab includes configurable AC and DC loads, which can be resistive, inductive, non-linear, or programmable.
Students can analyze:
- Load prioritization and shedding
- Demand response strategies
- Impact of load type on power quality
- Load behavior during islanded operation
- Critical vs non-critical load management
Smart switching and load control allow realistic simulation of residential, commercial, and industrial microgrid scenarios.
4. Central Energy Management System (EMS): The EMS is the brain of the microgrid. It monitors generation, storage, grid status, and loads in real time and makes decisions based on predefined or user-developed logic.
EMS capabilities include:
- Real-time monitoring of voltage, current, power, frequency, and SoC
- Power flow control between sources, storage, grid, and loads
- Automatic islanding and grid reconnection
- Black start operation
- Load priority and shedding logic
- Renewable maximization strategies
- Cost and efficiency optimization
- Manual, automatic, and remote operation
The EMS software is editable and programmable, allowing students and researchers to implement custom algorithms and validate them on real hardware.
