Transmission & Management Systems
Intelligent Grid Infrastructure for a Decentralized Energy Era
As the global energy landscape undergoes a profound transformation—marked by the exponential growth of distributed generation, the electrification of transportation, and the critical need for grid stability—AIMRSE’s Transmission & Management Systems division stands at the forefront of intelligent infrastructure solutions. We engineer and deploy advanced systems that enable the reliable, efficient, and secure transmission, distribution, and management of electrical energy, from large-scale utility grids to localized microgrids and electric vehicle (EV) charging networks.
Our mission is to bridge the gap between intermittent renewable generation and consistent, high-quality power delivery. We provide the hardware and software intelligence that transforms simple electrical networks into resilient, adaptive, and future-proof smart grids. Whether integrating megawatts of solar and wind power, managing bidirectional power flows from vehicle-to-grid (V2G) systems, or ensuring power quality for sensitive industrial loads, AIMRSE delivers solutions that meet the most demanding technical and operational standards.
Our portfolio is designed for system operators, utilities, commercial fleet managers, municipalities, and EPC contractors who require more than just components—they need a strategic partner with deep domain expertise in power electronics, grid communications, and energy management. We offer not only state-of-the-art equipment but also comprehensive support in system design, interoperability testing, and lifecycle optimization.
Core Product Portfolio
EV Charging Stations
AIMRSE's EV Charging Stations portfolio encompasses a complete ecosystem for electric vehicle supply equipment (EVSE), engineered for reliability, scalability, and smart grid integration. Our range includes Level 2 AC chargers for workplace and public destinations, DC Fast Chargers (DCFC) for highway corridors, and Ultra-Fast Chargers capable of delivering over 350 kW for next-generation EVs. Crucially, we specialize in Vehicle-to-Grid (V2G) bidirectional chargers, which transform EV batteries into distributed energy resources, providing grid services like frequency regulation and peak shaving. All our stations are built with robust thermal management, feature advanced user authentication and payment systems, and are fully compliant with OCPP 2.0.1 for seamless network management.

EV Charging Technology & Grid Integration
Our EV Charging Stations are built on a modular power electronics platform using silicon carbide (SiC) MOSFETs for the DC fast-charging units, enabling switching frequencies above 50 kHz for reduced size and loss. The charging logic implements ISO 15118-2/20 for Plug & Charge and V2G communication, supporting both DIN SPEC 70121 and CCS Combo 1/2 standards. For grid integration, our chargers feature built-in advanced metering infrastructure (AMI) and can receive external signals via OpenADR 2.0b for demand response events. The V2G units utilize a galvanically isolated dual-active-bridge (DAB) topology, allowing seamless four-quadrant operation for both charging and discharging with 97% round-trip efficiency.
Advanced Grid Management & PCS Architecture
The core of our Power Conversion Systems is a three-level Neutral Point Clamped (NPC) inverter topology, which reduces voltage stress on semiconductors and lowers output harmonic content. The control firmware implements a multi-loop architecture with inner current control (using PR or dq-frame controllers) and outer grid-forming droop control. This enables seamless transition between grid-tied and islanded modes in less than 20ms. Our EMS platform utilizes a distributed optimization algorithm (model predictive control) to schedule storage and generation assets based on real-time pricing, weather forecasts, and load predictions, maximizing revenue in ancillary service markets.
Smart Substation Communication & Protection
Our IEC 61850-based substation systems implement Sampled Values (SV) over Ethernet for real-time current and voltage data from non-conventional instrument transformers, and Goose messaging for high-speed protection signaling. The IEDs support standardized logical nodes (e.g., PTOC for overcurrent, PDIF for differential protection) for interoperability. We integrate Phasor Measurement Units (PMUs) synchronized via GPS/IEEE 1588 PTP for wide-area monitoring and state estimation, enabling visualization of phase angles across the grid for stability assessment.
Power Quality & Harmonic Mitigation Technology
Our Active Harmonic Filters employ a shunt-connected Voltage Source Inverter (VSI) with an LCL output filter. They use a synchronous reference frame (d-q) based detection algorithm to isolate harmonic components from the load current in real-time. The compensating current reference is generated and injected with a latency of under 50 microseconds. For STATCOM applications, we utilize a cascaded H-bridge multilevel converter for medium-voltage direct connection, providing continuous capacitive or inductive reactive power from full load to zero load without switching steps.
The AIMRSE Advantage in Grid Systems
End-to-End System Integration
We provide fully integrated solutions, not just standalone components. Our engineering team designs and commissions complete systems—from site layout and electrical studies to communications network configuration and SCADA HMI customization—ensuring seamless interoperability and optimized performance.
Cybersecurity by Design
Every AIMRSE grid and charging system is built with cybersecurity as a foundational layer. We implement hardware security modules (HSM), role-based access control (RBAC), encrypted communication (TLS 1.3), and regular firmware updates to protect against evolving threats, ensuring compliance with NERC CIP, IEC 62443, and ISO/SAE 21434 standards.
Future-Proof & Scalable Architecture
Our modular hardware designs and software-defined platforms allow for easy capacity expansion and feature upgrades. Whether adding more EV charging stalls, integrating new renewable generation, or adopting new grid codes, AIMRSE systems are designed to adapt without requiring costly replacements.
