Abstract
Various implementations described herein are directed to systems, apparatuses and methods for operating stand-alone power systems. The systems may include power generators (e.g., photovoltaic generators and/or wind turbines), storage devices (e.g., batteries and/or flywheels), power modules (e.g., power converters) and loads. The methods may include various methods for monitoring, determining, controlling and/or predicting system power generation, system power storage and system power consumption.
Claims20
A system, comprising:
- a plurality of power sources;
- a string of power converters connected to the plurality of power sources, wherein two or more outputs, of the string of power converters, are connected in series;
- and
- a controller configured to send, based on a requirement of a direct current (DC) load and to one or more power converters of the string of power converters, one or more instructions to output DC power, and
- wherein the one or more power converters of the string of power converters are configured to output, based on receiving the instruction, the DC power;
- wherein the DC load is configured to consume DC power;
- wherein the DC load comprises communication equipment;
- and
- wherein the DC load is not connected to an alternating current (AC) grid.
6 more elements
A method, comprising:
- receiving, by each of a plurality of power converters and by using Maximum Power Point Tracking (MPPT), a direct current (DC) input power from a different power source of a plurality of power sources, wherein two or more outputs, of the plurality of power converters, are connected in series;
- determining, by a controller, that a DC output power, produced by the plurality of power converters based on the DC input power, will satisfy a requirement of a DC load;
- sending, by the controller, to the plurality of power converters, and based on the determining, one or more instructions to output the DC output power;
- and
- outputting, by the plurality of power converters and based on the one or more instructions, the DC output power,
- wherein:
- the DC load is configured to consume DC power,
- the DC load comprises communication equipment, and
- the DC load is not connected to an alternating current (AC) grid.
