The Impact of Electric Vehicle Charging on Grid Stability

There is more to EV charging than providing the kWh. What happens in the first few seconds after a fault? Be that power or communication or control systems

EV charging is a major new load on the electricity grid. It will have a significant impact on grid short term frequency and voltage stability, and cascade fault prevention and recovery.

Smart charging, controlled by software systems to charge off-peak, will behave in a significantly different way to traditional system demand, especially during grid transient events or post power cut. This introduces system risks that have not been seen before, which will require mitigation actions.

Get it right and smart charging, combined with V2G has the potential to enhance system security and save hundreds of millions of pounds per year.

The key findings of the project will be presented in webinar at 10am on 30th November 2022 (Note revised date) which presents the conclusions from Project Resilient Electric Vehicle Charging (REV) which Sygensys has undertaken for National Grid ESO.

Could EVs overload the power grid? 

As nations prepare for an onslaught of electric cars on the road, we delve into the impact such demand could have on the national grid.

An £11.4m programme of funding by the Department for Business, Energy and Industrial Strategy is getting off the ground to make it easier for an electric vehicle (EV) to return electricity to the network during times of peak loading. Since June, all new private chargepoints must be smart enough to adjust their rate of charge in response to external signals, in order to ease demand on the network at times like the evening peak.

Innovate UK EDGE sparks growth at EV grid pioneer Sygensys

Start-up Sygensys is enhancing the performance and reliability of electric vehicle (EV) charging and vehicle to grid technology. Supported by Innovate UK EDGE, it aims to ensure the effective use of renewable energy sources through its demand management and energy storage systems.

“What we are trying to do is to ensure that the electricity grid remains reliable with the mass adoption of EVs,” says Andrew Larkins, CEO at Sygensys. “EVs are going to need a lot of energy to charge and are a potential threat to electricity grid reliability as a result. Having smart systems around them should enhance reliability.”

Sygensys: harnessing renewable energy to secure the grid

Sygensys’s vision is to lever the potential of bi-directional power flow from electric vehicles and battery energy storage systems to help balance electricity supply and demand, both on public grids and local microgrids.

The company is working on developing demand side management solutions which address the cyber and security risks arising at the grid’s edge, enabling the development of demand side response markets.

Delivering a smart and secure electricity system: the interoperability and cyber security of energy smart appliances and remote load control

Sygensys is delighted that BEIS have referenced Project REV within a consultation document. This is one good example of how our work for National Grid ESO is influencing regulators both in UK and internationally.

Managing Unexpected Risks: Handling Rare and Severe Events Now and in the Future

This seminar considered resilience in critical systems, i.e. how to identify, assess and manage recovery from events which are rare, unexpected and have high impact. Tragedies such as 9/11 or the loss of Malaysia Airlines Flight 370 might be high-profile examples. Such ‘Black Swan’ events are generally explainable with hindsight, making them appear predictable after the event.

Resilient timing for electricity distributed energy resource management 

Sygensys was delighted to be awarded £44,738 by UKRI for a feasibility study.

This project will help Sygensys develop its innovate products and services which need a resilient timing reference to measure electricity grid performance. Our system needs to be robust, providing reliable operation when subjected to equipment failure, natural disaster, or human action such as cyber-attack.
