Abstract

A method for allocating capacity of an energy storage associated with at least one passenger transport installation includes continuously monitoring performance data of the energy storage; obtaining first data associated with operating the at least one passenger transport installation; identifying different uses for the energy stored in the energy storage; determining an allocation of energy storage capacity available for the different uses based on the performance data and the first data; and applying the determined allocation.

First claim

The invention claimed is:

1. A method for allocating capacity of at least one energy storage associated with at least one passenger transport installation, the method comprising:
continuously monitoring performance data of the at least one energy storage;
obtaining first data associated with operating the at least one passenger transport installation;
identifying different uses for the energy stored in the at least one energy storage;
determining an allocation of energy storage capacity available for the different uses based on the performance data and the first data; and
applying the determined allocation of energy storage capacity to the different uses to an operation of the at least one passenger transport installation,
wherein the first data comprises at least one of traffic forecast data or load forecast data of the at least one passenger transport installation.

2. The method of claim 1 , further comprising:
obtaining second data from at least one external data source, the second data being independent from operating the at least one passenger transport installation; and
determining the allocation of the energy storage capacity available for the different uses based on the performance data, the first data and the second data.

3. The method of claim 2 , wherein the second data comprises at least one of weather forecast data, utility signal data, grid frequency measurement data, solar photovoltaic load profile data, building load data, electricity cost data, or demand response market data.

4. The method of claim 1 , wherein determining the allocation of energy storage capacity available for different uses comprises determining allocation for at least one of a demand response, frequency regulation, peak power shaving, solar photovoltaic optimization, or backup power for the at least one passenger transport installation.

5. The method of claim 1 , wherein the performance data comprises at least one of a charge state, a charge cycle, a load profile, a health state or the maximum charging and discharging current or power of the at least one energy storage.

6. The method of claim 1 , further comprising:
sending data relating to the allocation of energy storage capacity available for at least one of demand response, frequency regulation, grid voltage regulation or local renewable energy optimization uses to an external control platform;
receiving an activation signal from the external control platform instructing to implement power grid balancing functions; and
taking the activation signal into account in determining the allocation of the energy storage capacity available for the different uses.

7. A computer program comprising a non-transitory computer-readable storage medium having program code stored therein, which when executed by at least one processing unit, causes the at least one processor to perform the method of claim 1 .

8. A non-transitory computer readable medium comprising program code, which when executed by at least one processor, causes the at least one processor to perform the method of claim 1 .

9. The method of claim 2 , wherein determining the allocation of energy storage capacity available for different uses comprises determining allocation for at least one of a demand response, frequency regulation, peak power shaving, solar photovoltaic optimization, or backup power for the at least one passenger transport installation.

10. The method of claim 1 , wherein the allocation of energy storage capacity available for the different uses is dynamically determined and the determined allocation is not fixed, such that available capacity of the energy storage allocated for each of the different uses varies as a function of time.

11. The method of claim 1 , wherein the available capacity of the energy storage is allocated to the different uses as a function of time and is dynamically applied to the different uses as a function of time, and wherein the method further comprises the step of operating the at least one passenger transport installation with optimized utilization of the at least one energy storage according to the dynamically applied allocation.

12. An energy storage management system for allocating capacity of at least one energy storage associated with at least one passenger transport installation, the system comprising:
a memory, and a processor, wherein the processor is configured to:
continuously monitor performance data of the at least one energy storage;
obtain first data associated with operating the at least one passenger transport installation;
identify different uses for the energy stored in the at least one energy storage;
determine an allocation of energy storage capacity available for the different uses based on the performance data and the first data; and
apply the determined allocation of energy storage capacity to the different uses so as to optimize share of the energy stored in the at least one energy storage,

wherein the first data comprises at least one of traffic forecast data or load forecast data of the at least one passenger transport installation.

13. The system of claim 12 , further comprising a network interface, wherein the processor is further configured to:
obtain second data from at least one external data source through the network interface, the second data being independent from operating the at least one passenger transport installation; and
determine the allocation of the energy storage capacity available for the different uses based on the performance data, the first data and the second data.

14. The system of claim 13 , wherein the second data comprises at least one of weather forecast data, utility signal data, grid frequency measurement data, solar photovoltaic load profile data, building load data, electricity cost data, or demand response market data.

15. The system of claim 12 , wherein the means for determining an allocation of energy storage capacity available for different uses are configured to determine the allocation for at least one of a demand response, frequency regulation, peak power shaving, solar photovoltaic optimization, or backup power for the at least one passenger transport installation.

16. The system of claim 12 , wherein the performance data comprises at least one of a charge state, a charge cycle, a load profile, a health state or the maximum charging and discharging current or power of the at least one energy storage.

17. The system of claim 12 , further comprising a network interface, wherein the processor is further configured to:
send data relating to an allocation of energy storage capacity available for at least one of demand response, frequency regulation, grid voltage regulation or local renewable energy optimization uses to an external control platform through the network interface;
receive an activation signal from the external control platform instructing through the network interface to implement power grid balancing functions; and
take the activation signal into account in determining the allocation of the energy storage capacity available for the different uses.
