摘要： An energy storage and delivery system includes an elevator, where the elevator is operable to move one or more blocks from a lower elevation to a higher elevation to store energy (e.g., via the potential energy of the block in the higher elevation) and operable to move one or more blocks from a higher elevation to a lower elevation (e.g., by gravity) to generate electricity (e.g., via the kinetic energy of the block when moved to the lower elevation). The energy storage system can, for example, store electricity generated from solar power as potential energy in the stacked blocks during daytime hours when solar power is available, and can convert the potential energy in the stacked blocks into electricity during nighttime hours when solar energy is not available, and deliver the converted electricity to the electrical grid.

摘要： A stored power production source management device of an embodiment includes an acquisition unit, a power storage management unit, and a discharging management unit. The acquisition unit acquires first information indicating a power supply source when a power storage is charged. The power storage management unit stores information indicating a power supply source for power stored in the power storage in a data storage in association with an amount of stored power on the basis of the first information. The discharging management unit specifies a power supply source for the power to be discharged on the basis of information indicating the power supply source stored in the data storage when the power storage is discharged, and subtracts the amount of power to be discharged from the amount of power corresponding to the specified power supply source in the data storage.

摘要： A renewable energy powered thermal processing system is formed from a renewable energy source operably connected to an inverter via a charge controller. In one embodiment, a solar renewable energy source is operably connected to the inverter via a solar charge controller. The inverter is connected to a renewable energy storage device and further conditions the current for the thermal processing power supply, which then delivers energy to a thermal processing unit. A supplemental renewable energy source, such as wind, may further be operably connected to the inverter via a supplemental charge controller. As such, the thermal processing unit can be powered solely by renewable energy directly or stored renewable energy within the renewable energy storage device to provide a standalone, grid-independent renewable energy powered thermal processing system. Optionally, a grid tie may further selectively connect the system to an external power grid as a backup source of energy.

摘要： A tertiary frequency modulation method for a power system, AGC based on power plant input performs active power regulation for tertiary frequency modulation in different modes in power plants in case of secondary frequency modulation failure of the power system and unidirectional deviation of grid frequency from rated frequency for a period: perform tertiary frequency modulation based on the reserved capacity of the secondary frequency modulation or the regulation amount of primary frequency modulation or random parameters. The invention relates to tertiary frequency modulation whose action sequence is later than that of the primary frequency modulation and the secondary frequency modulation to realize astatic frequency regulation. Compared with the secondary frequency modulation function, the tertiary frequency modulation function completely gets rid of the dependence on a central node; compared with the primary frequency modulation function, the tertiary frequency modulation method undoubtedly has higher stability and sustainability in the regulation effect.

摘要： The generation of surplus power in a power generation system using renewable energy is prevented. An operation support device for making a start determination regarding preparation for the operation of a load device includes a determination unit that makes a start determination regarding preparation for the operation of the load device when history information indicating the history of the energy storage amount in an energy storage device corresponds to a predetermined state. The load device is a device that requires a preparation time from the start of operation preparation to the start of operation, and can consume during operation at least one of the power generated by a power generation device using renewable energy and the discharged power of the energy storage device that can store power generated by the power generation device.

摘要： A controller for a system of equipment that operate to produce or consume one or more resources includes one or more processing circuits configured to generate a resource balance constraint using a balance between a first amount of each resource and a second amount of each resource. The first amount of each resource includes at least an amount of the resource produced by the equipment. The second amount of each resource includes at least an amount of the resource consumed by the equipment. The one or more processing circuits are configured to perform a control process using the resource balance constraint to determine amounts of each resource to be produced or consumed by the equipment and operate the equipment to produce or consume the amounts of each resource determined by the control process.

摘要： Disclosed is an optimal power flow-based hierarchical control method for a distributed energy storage system (ESS), where the method divides control of an energy storage cluster into three layers, performs primary and secondary control to realize intra-cluster control, and performs tertiary control to realize inter-cluster control. In the primary control, droop coefficients are set to realize intra-cluster basic power distribution. In the secondary control, a frequency/voltage shift and uneven power distribution that are caused by a droop are compensated for based on a consistency algorithm. In the tertiary control, a central controller is set, a solution of an optimal power flow is calculated and delivered to each cluster as a control signal, and the control signal is tracked in real time through the secondary control and the primary control. The method adjusts a reference voltage of each energy storage cluster without requiring a common bus.
