1. A method for managing an energy system having one or more renewable energy sources, one or more energy storage devices, one or more loads, and a connection for connecting at least temporarily to an external non-renewable energy source, the method comprising the steps of:
generating a prediction of energy demand of the loads using historical energy demand data;
generating a prediction of renewable energy availability from the renewable energy sources using weather forecast data;
determining an amount of energy to be obtained from the external non-renewable energy source in dependence on the prediction of renewable energy availability and the prediction of energy demand;
generating an energy conservation strategy to minimise use of the external non-renewable energy source using the predictions and determined energy amount, the energy conservation strategy comprising:
i) generating a load-shedding strategy comprising periods of interruption of energy supply to the one or more loads; and
ii) generating, based on the determined amount of energy to be obtained from the external non-renewable energy source, a charge plan for charging the one or more energy storage devices, the charge plan specifying one or more charging sources and/or charging times for charging the one or more energy storage devices in order that a) a minimum charge level to be maintained for the one or more energy storage devices, b) a required charge level to be achieved for the one or more energy storage devices, wherein the required charge level is to be achieved at least once in a given time period, wherein the charge plan is generated based on an energy storage device charging constraint related to battery health and/or wherein the charge plan is generated based on the prediction of renewable energy availability extending beyond 24 hours; and
adjusting energy supplied to one or more of the energy storage devices and/or one or more of the loads automatically according to the energy conservation strategy.
