The FIRE experiment1 will present a net electric power demand approaching 1000MW for 10's of seconds, repeated once every 2 hours, delivered to the load via thyristor AC/DC converters which exhibit a widely varying power factor. The issues associated with the supply of such a load from the utility grid can be divided into two categories:
transmission line power flow vs. capacity voltage deviation within the grid vs. limits frequency deviation within the grid vs. limits loading of electrical equipment (e.g. generators) control of power generation (e.g. steam turbines)
control and monitoring of grid power flow coordination of protection systems repetitive cycling of power system equipment allowance for contingency on tie line power flows power flow reversal harmonic content of load power and energy monitoring, billing rate structure
