According to an embodiment, a power management apparatus is provided with storage means, discharge plan creation means, discharge instruction means. The storage means stores a discharge amount of a power storage device to a distribution system, correspondingly to a prescribed parameter. The discharge plan creation means, when storable regenerative power is generated, creates a discharge plan to determine a discharge amount of the power storage device, from past data stored in the storage means, of regenerative power amount of a train and the discharge amount of the power storage device to the distribution system. The discharge instruction means outputs a discharge instruction to the power storage device.

An embodiment of an electric vehicle drive apparatus includes a rotary electric motor, an electromagnet apparatus, an electric motor controller, and an electromagnet controller. The rotary electric motor drives at least one wheel. The electromagnet controller generates at least one of an attraction force between a rail and a bogie, and a propulsion force. The electromagnet controller controls the electromagnet apparatus. The rotary electric motor and the electromagnet apparatus are provided on the same bogie.

Electric vehicle drive apparatus, method of driving an electric vehicle, and program

A solar receiver is disposed on a top portion of a tower provided upright on the ground for heating a compressible working fluid by means of heat converted from sunlight collected by heliostats disposed on the ground, to raise the temperature of the compressible working fluid. The solar receiver has modules disposed back-to-back, and each of which includes a casing having a bottom plate to be fixed to the top-portion upper surface of the tower. A heat-transfer-tube unit is accommodated in the casing and includes heat transfer tubes. A sunlight inlet port having a circular shape in front view or an elliptical shape in front view is provided at the center portion of a plate-like member whose lower end is connected to an outer circumferential end of the bottom plate to constitute the casing and that extends obliquely upward from the outer circumferential end.
