Simulating design choices for the future Net Zero energy system

Dynamic Energy System Simulation (DESS) analyses the behaviour of future energy system designs.

Energy Systems Catapult utilises a first-of-a-kind simulation tool, EnergyPath® Operations, to work with government, regulators, academics and industry in order to assess system design choices, business models and information technology solutions – by considering operational decision-making and its effects on the energy system from local to national scale.

This enables energy system design changes to be explored more quickly and more cheaply than through real-world trials. Supporting decision-making that integrates the physical, digital and market systems, against the background of rapid technological and societal change.

DESS can provide powerful insights into the outcomes for different stakeholders in future worlds with radical differences from today – such as high uptake of Electric Vehicles.

Dynamic Energy System Simulation offers...

Integrated commercial, digital and physical simulation

Analysis of not only the technical aspects of energy systems but also the markets and information systems that underpin them, and the coupling between these.

Reduced time, cost and risk

A safe and low-cost environment to test proposals before undertaking expensive and time-consuming real-world trials.

Whole Systems perspective

Representation of actors across the energy system, from upstream generation of energy to the end customer, across current and future energy vectors.

Operational decision-making foundation

The ability to examine choices and actions made by individual actors and their effects on the system, with a time granularity of seconds or minutes rather than years.

Case Studies

Cold Start - extended power outage under severe weather conditions

Energy Systems Catapult collaborated with UK Power Networks under Network Innovation Allowance funding to investigate the effects of future electrification of domestic heating and transport on the peaks in demand that occur after long outages.

With uptake of electric vehicles and electrified heating expected to increase substantially in the coming decades, an extended power outage under severe weather conditions in 2030 – known as a Cold Start – could lead to a demand surge as electrical devices are reactivated, far above today’s peak levels.

Using our innovative EnergyPath® Operations tool, we simulated a portion of UK Power Networks’ electricity network to understand how electricity-consuming appliances would behave after different outage scenarios, and the physical impacts of this behaviour on assets in the network – in terms of power flows, voltages, loading and voltage unbalance.

The results will allow UK Power Networks to plan and operate their network in the face of future low-carbon technology uptake, and pave the way for further work to:

  • Identify network areas with high risk of adverse effects from power restoration after Cold Start.
  • Evaluate mitigation measures such as operational policies, network controls, demand-side flexibility and conventional reinforcement.
  • Explore novel mitigation methods based on in-home appliance flexibility.
