Abstract: In this disclosure, the energy management problem of the D-IEGS with FFR is analyzed, so as to enhance the frequency stability of the main grid. The post-disturbance frequency response behaviors of both the main grid and the D-IEGS are precisely depicted, where the dead zones, limiting ranges and time constant of the governors are considered. The frequency regulation units of the D-IEGS include GTs and P2G units, whose impacts of providing frequency regulation service on the gas networks are quantified. Considering the time-scale similarity of the frequency dynamics and the dynamics of the GDN, the gas flow dynamics model is adopted. The frequency response dynamics of the GTs and P2G units, and the gas flow dynamics of the GDN, a variable-step difference scheme and a binary variable reduction method are devised.

Abstract: The invention is directed at a substantially continuous unbroken frequency curve during operation modes from dump load operation, reverse power operation, low load operation and normal operation. Controlling functions are active during all operation modes except the engine controller which is on standby when in an engine stopped mode. This all together gives a dynamic, robust and flexible energy supply, preferably in a range of 50 to 50.3 Hz. Further the clutching is performed substantially without fluctuations. The invention substantially prevents harmonic fluctuations to the grid. The main reactive power compensation is handled by the alternator always connected to the grid and rotating. Further reactive power compensation is done by a standard automatic reactive power compensation system. The invention contributes to stabilization of grid fluctuations with its mechanical inertia from the rotating alternator in the engine stopped mode and also with the engine in the other modes.

Abstract: A system comprises a power source and two power rails coupled to the power source. A storage device, comprising a non-volatile memory, a cache coupled to the non-volatile memory, and a control pin, is coupled to the second power rail. A power management controller is coupled to the first power rail and to a control pin of the storage device. The power management controller stops the provision of power via the first power rail and provides a signal to the storage device via the control pin when the provision of power via the first power rail is stopped. The storage device continues to receive power from the second power rail when the provision of power via the first power rail is stopped. The storage device stores data from the cache to the non-volatile memory in response to the receipt of the signal via the control pin.
