Microgrid Power Systems (AEL-MGP)
PL-826478
The "AEL-MGP" Microgrid Power System by EDIBON is a comprehensive training unit designed to facilitate hands-on learning of microgrid power systems. This trainer allows users to explore the architecture, management, and control of hybrid systems integrating renewable energy sources. It replicates an isolated grid structure featuring renewable resources, such as photovoltaic, wind, and hydroelectric power, enhanced with industry-grade components to simulate real-world microgrid management scenarios.
The system includes applications to model varied microgrid conditions, which EDIBON recommends as foundational modules: Hydroelectric Power Plants, Wind Power Plants, Battery Energy Storage, and Flywheel Energy Storage. Due to renewable energy sources' low inertia, a Conventional Energy Power Plant (PWP-CE) is necessary to maintain grid stability, emulating diesel or gas power sources commonly used in isolated grids.
Key Applications
- PWP-CE: Conventional Energy Power Plant This foundational module provides baseline power, defining the microgrid’s frequency and voltage parameters. It includes an electric motor coupled with a three-phase synchronous generator, controlled by a multifunction controller to regulate parameters such as speed, voltage, and power output. It offers ANSI-standard protections and a dynamic load control module for creating demand profiles, allowing users to analyze energy generation, consumption, and load profiles.
- PWP-HE: Hydroelectric Power Plants Focused on energy supply flexibility during peak demand, this module simulates hydroelectric energy contributions to the microgrid. It includes a turbine-generator group with a multifunction controller to manage power distribution and energy production in real time.
- PWP-WE: Wind Power Plants This module replicates a wind power plant within a microgrid context, using an induction generator to simulate wind energy distribution. It includes a network analyzer and a multifunction controller to manage power outputs and active energy injection.
- PWP-PE: Photovoltaic Power Plants This module uses a three-phase inverter with a photovoltaic panel simulator to study solar energy management, including MPPT, inverter efficiency, and reactive energy. Users can set generation parameters and observe real-time energy output via network analyzers.
- PWP-BE: Battery Energy Storage This component highlights energy storage through batteries, simulating conditions where renewable resources are low, enabling stored energy utilization. The module’s bidirectional inverter allows quick power output to support demand fluctuations.
- PWP-FE: Flywheel Storage Demonstrates kinetic energy storage via a flywheel, with a bidirectional inverter for efficient energy intake and release. It enables renewable sources like wind and hydro to react to demand surges effectively.
Advanced Features and SCADA Integration
An optional fault study kit includes an advanced protection relay and fault injection module to simulate single-phase, two-phase, or three-phase faults. Additionally, the EMG-SCADA software facilitates comprehensive microgrid management, offering real-time planning, dispatching, and power balancing across renewable sources and conventional generation based on cost efficiency and grid technical requirements.
Users can combine multiple modules to replicate realistic power dispatches based on marginal costs, minimum synchronous generation requirements, and other system parameters, enabling practical learning in scalable microgrid setups.
