Digital solutions for lean & flexible power distribution grids in the energy transition

Our vision

Power distribution grids are becoming a complex cyber-physical infrastructure.
Managing this infrastructure requires great software.

The electricity distribution sector is undergoing rapid change in the context of the energy transition, and the increasing digitalization of almost every aspect of grid management. Operational practices are changing, not only for Distribution System Operators, but also for all players in the field of electricity distribution: local authorities, regulators, network users themselves, etc.

These evolutions of business activities lead to a need for modernization of the technical software that is used to model, simulate, optimize, supervise and control the grid.

Whether the objective is to process rapidly, massively and transparently the growing flow of connection requests linked to the development of decentralized production and electrical mobility, or to anticipate the needs for network reinforcement necessary in the long term, or to experiment with new “smart grids” technical solutions, Roseau Technologies accompanies its clients in the digital transformation of all their activities linked to the engineering of electrical networks.

Our software solutions

A comprehensive software suite for the digitalization of the power distribution industry

Renewable Energy Project Developers

Renewable energy developers need to target areas where the grid has sufficient hosting capacity, to prioritise their projects based on the risk of facing high connection costs, to optimise connection requests by adjusting their projects to the grid if needed, and to be able to understand and analyse the connection offers they receive from DSOs. Roseau Technologies’ Grid Capacity offers renewable energy developers all these features, packed into an easy-to-use web

Distribution Network Operators

Digital twins are a hot topic, but how can DSOs turn massive legacy GIS data into an electrical model of their network that will seamlessly  and regularly transfer into commercial electrical simulation software?

Learn how Roseau-ETL, with a track record of over 1.5M of km of distribution network successfully modelled, helps distribution utilities meet this challenge.

Power flow solvers are commonplace, but few are as convenient and powerful as Roseau Load Flow! With its streamlined API that allows object-oriented modelling directly in Python language, and its ability to capture complex models such as meshed, unbalanced polyphase networks with any type of voltage-dependent devices, Roseau Load Flow makes it easy to simulate the integration of flexible generators and loads in the power distribution network with just a few lines of code.

				
					# Create two buses
source_bus = Bus(id="sb", phases="abcn")
load_bus = Bus(id="lb", phases="abcn")

# Define the reference of potentials to be the neutral of the source bus
ground = Ground(id="gnd")
pref = PotentialRef(id="pref", element=ground)  # Fix the potential of the ground at 0 V
ground.connect(source_bus, phase="n")

# Create a LV source at the first bus
un = 400 / np.sqrt(3)  # Volts (phase-to-neutral because the source is connected to the neutral)
source_voltages = [un, un * np.exp(-2j * np.pi / 3), un * np.exp(2j * np.pi / 3)]
vs = VoltageSource(id="vs", bus=source_bus, phases="abcn", voltages=source_voltages)

# Add a load at the second bus
load = PowerLoad(id="load", bus=load_bus, phases="abcn", powers=[10e3 + 0j, 10e3, 10e3])  # VA

# Add a LV line between the source bus and the load bus
lp = LineParameters("lp", z_line=(0.1 + 0.0j) * np.eye(4, dtype=complex))  # R = 0.1 Ohm/km, X = 0
line = Line(id="line", bus1=source_bus, bus2=load_bus, phases="abcn", parameters=lp, length=2.0)

What makes us truly unique

A dual expertise

The power distribution sector is highly technical: working on its digitalization thus calls for strong skills not only in information technology, but also in electrical engineering. If you are looking for a team of experts from both fields working hand in hand, you have come to the right place.

A unique in-house smart-grid lab

Sure, it’s a poor workman who blames his tools; but also, it’s difficult to get any work done without proper equipment. Years of research & development have taught us that very specific hardware and software are needed to design, develop and validate smart grid technology, so we built our own smart grid lab to make sure we always had all the needed tools in our shed.
