Research is mainly focused on three systems of a smart grid – the infrastructure system, the management system, and the protection system.[51]. Early electric energy was produced near the device or service requiring that energy. National Grid had by now taken other measures to increase output at other generation sites (and demand had been reduced at those customer sites where the customer has volunteered for this to happen, in return for reimbursement, under demand-side response contracts with National Grid, or with their supplier). Failures are usually associated with generators or power transmission lines tripping circuit breakers due to faults leading to a loss of generation capacity for customers, or excess demand. Batteries of the type have traditionally been used for long-duration storage applications. It would allow management of the grid on all time scales from high-frequency switching devices on a microsecond scale, to wind and solar output variations on a minute scale, to the future effects of the carbon emissions generated by power production on a decade scale. As the energy market moves from fuel-based sources towards renewable energy, power production has the potential to become more volatile – making it harder to both predict and balance electrical supply.
