Maintaining security and quality of power supply has become a major concern for electricity providers as well as their customers.
To meet sustainable energy requirements and improve overall system reliability, modern electricity networks increasingly employ complex interconnections, intermittent and non-dispatchable renewable generation, nonlinear electronic equipment, and operate near physical security limits. These measures significantly reduce system inertia, damping and fault-withstanding levels which further result in degradation of supply security, reliability, and quality.
Although several software and/or hardware technologies exist to improve security and quality of supply, their effectiveness is limited to few specific problems which means that their wide adoption is uneconomical. Moreover, they pose further issues in control.
A technology that sits in the main energy conversion and distribution process, rather than as an auxiliary technology, sitting outside the main energy conversion and distribution chain, could efficiently ensure network integrity, and supply security and quality.
Faraday Grid Limited (FGL), a systems design and energy technology company, developed such a fundamental technology – the Faraday Exchanger: a single device featuring power-flow control, voltage/var regulation, power factor correction, phase-imbalance control, and power conditioning capabilities. Faraday Exchangers fit seamlessly into the existing electricity system, each individually providing – among others – the functionalities of traditional transformers, rectifiers, converters, and inverters.
Faraday Exchangers, unlike the existing technologies, sit within the main energy conversion and distribution process and auto-regulate their response to uplift the performance of the overall process to the highest extent. This technology fundamentally changes the way systemic problems have been approached by uniquely providing an effective single solution to a range of problems.
The Power Network Demonstration Centre (PNDC), a smart grid demonstration and testing facility, carried out an independent third-party validation of the Faraday Exchanger. Numerous tests compliant with the relevant industrial standards have been performed on the Faraday Exchanger by the technical experts of PNDC. PNDC prepared an independent technology validation report after postprocessing the test results against the relevant industrial standards.
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 (PDF) by Jagadeesh Gunda summarises the capabilities of the Faraday Grid technology.
