This project is a desktop study based on modelling and simulation looking into exploring the problem surrounding cold start/cold load pick-up.
This desktop study will inform UK Power Networks’ policy around cold start operation and will unlock future studies on technological applications and/or commercial solutions for the management of this issue. The simulations will investigate the phenomenon and will help UK Power Networks’ strategy for a low carbon/ electrified heat future.
A software tool will be used to aid the network simulation called EnergyPath® Operations, a tool developed by the Energy Systems Catapult for conducting in-house operational-timescale simulations of energy systems.
Cold Start is expected to be Phase 1 of a larger project. It is the first step towards understanding the issues related to cold load pick up and their extent. The findings will inform a second phase that will focus on how UK Power Networks will address these issues and will investigate a range of possible solutions. It is expected that UK Power Networks will develop Phase 2 of the project with other organisations based on the recommendations from Cold Start.
The overarching aim of the project is to improve the understanding of the issues associated with restoring electrical power to a distribution network segment after an extended period of time, where the wider GB electricity system has remained operational in the interim (“cold start”), in a future world where a greater proportion of domestic heating and transport are electrified.
The overall aim has been divided into the following Objectives:
• Objective 1: Simulate loads on electricity system in a future “cold start” scenario with greater electrification of heat and transport.
• Objective 2: Derive insights from model data regarding future electricity system (e.g. new After Diversity Maximum Demand values and potential resulting impact on design standards).
• Objective 3: Create recommendations on integrating findings into UK Power Networks’ Business as Usual processes.
The intention is that the outcome of this work will contribute to improve UK Power Networks’ ability to respond to future demand scenarios. In particular, the broader landscape of work within which this project is situated seeks to provide meaningful recommendations for approaches to handle cold start, involving cost-benefit comparisons between network reinforcement and smart control systems.
