Spotlight Q&A - Hitachi ABB Power Grid (final)


Blog Highlights

  • Hitachi Energy Power Grids need to integrate various DERs and control multiple loads in a complex system environment.

  • Before HIL, Software in the Loop was used to develop control algorithms but a system using real controllers was needed to ensure the system works.
  • Controller Hardware-in-the-Loop (C-HIL) gives grid flexibility and adaptability to cover many test cases at an appropriate fidelity.
  • C-HIL can be used from the early design phase all the way into operational performance and customer demonstration with factory acceptance testing.
  • For microgrids with BESS and solar PV, the seamless transition from grid-connected to islanded mode was demonstrated using C-HIL.
  • “HIL Tested” for Hitachi ABB Power Grids means great performance.

Inverter ABB (Top) - Metodologies


Energy networks worldwide are evolving to become increasingly more decentralized, fueled by new developments in many sectors: Industry 4.0, Distributed Energy Resources (DERs), electric vehicles (EVs), and more. This means a greater need for robust local control and storage systems to avoid dangerous disruptions or blackouts. These factors are driving innovation, particularly in two areas: new power electronic controllers for energy storage and DERs, and new system-level control architectures that can control microgrids effectively in a wider range of conditions.

What is the challenge? 


The electric power systems are going through a transition that encompasses digitalization, decentralization, and decarbonization. This will lead to more resilient power grids due to the higher adoption of digital technologies, renewable power sources, and new battery storage systems. Everyone will benefit from the enhanced control, efficiency, and maintenance capabilities, but it all has to start from smart test-driven design. There is a need for integrated solutions to improve power system performance which will be data-based, so the systems are built with the end specs in mind and thoroughly tested throughout all possible test scenarios in an automated manner.

The Ship is a Microgrid (Part II) - Why is this so hard to design and build?

Ship is a microgrid 2 II hero image

This is an extension of our previous blog relating a ship's power system to a microgrid - interconnected loads (propulsion, C4ISR, propulsion, and auxiliary) and distributed energy resources (power generation, distribution, and energy storage) acting as a controllable entity. We will be describing a layman’s perspective on digital engineering as it applies to microgrid design, building, commissioning, operation, and maintenance or lifecycle of a ship.

4 ways Controller Hardware in the Loop and Model-Based Engineering are Reducing Risk


Reduce Risk






Industry 4.0 is dawning, and digitalization, decarbonization, and decentralization (aka D3) are fueling the electric grid (r)evolution. D3, in turn, creates opportunities for immense value creation, but invokes new technologies and design concepts, and change brings risk.
