Until recently, the UK government’s future energy plans relied heavily on expensive new nuclear power plants to provide baseload capacity as old fossil fuel plants shut down. This was also going to ensure grid stability to support increased intermittent and volatile renewable generation. However, the energy system is fundamentally changing. We don’t need expensive nuclear power to keep the lights on – a more flexible energy system will enable renewables to flourish.
The Power Network Demonstration Centre (PNDC), a smart grid demonstration and testing facility, carried out an independent third-party validation of the Faraday Exchanger. The tests carried out by PNDC reconfirmed that the Faraday Exchanger does offer the intended functionalities (voltage regulation, power-factor correction and power-quality control) that are beyond what can be provided by one single technology to utilities and end-users of electricity. This means that wide adoption of the FG technology will result in improved power quality and reliability, increased equipment lifetime, and reduced-capital investment in mitigation technologies. Employing the key findings from PNDC validation report, this whitepaper by Jagadeesh Gunda summarises the capabilities of the Faraday Grid technology.
In the current hardware of electricity systems, the supply-demand-balance has a very important implication for maintaining the system’s frequency, which needs to be stable each second of the day for the system to function properly. Non-standard frequencies can harm both transformers and appliances in people’s homes. As the energy mix changes, the feasibility of utility-scale photovoltaics as a frequency response is an area of current interest and research. The Faraday Grid resolves short-term balancing issues by modulating power flows to reduce their noise, dynamically managing the voltage and the frequency in the electricity grid in doing so.
