Abstract:
1. A method for controlling operation of a power supply system for supplying electrical power to a power consuming device, said power supply system comprising a climate-dependent source of electrical energy, an auxiliary source of electrical energy, and an energy storage device in electrical connection with said sources of electrical energy for storing electrical energy generated thereby, at least said climate-dependent source and said energy storage device being connectable to said power consuming device for supplying electrical energy thereto, wherein said method comprises: acquiring power consumption data indicative of an expected future power consumption of said power consuming device, energy storage data indicative of a current energy storage level of said energy storage device, and power supply data indicative of a current supply of electrical power from said climate-dependent source of electrical energy; supplying in response to insufficient power being available from said climate-dependent source, electrical power from said energy storage device to said power consuming device; and dynamically determining, based on said acquired power consumption data, energy storage data and power supply data, an energy storage threshold level at which electrical energy should be supplied to said energy storage device to enable future operation of said power consuming device without controlling the operation of the power consuming device.
