Abstract: There is provided a computer-implemented method for controlling operation of a renewable energy system electrically connected with an electricity network over a period of time including a series of time segments. The method comprises: obtaining a plurality of electricity generation values, each of the electricity generation values representing an amount of electricity generated by the renewable energy system in a time segment of the series of time segments; obtaining a plurality of electrical load values, each of the electrical load values representing an amount of electricity consumed by an electrical load powered by the renewable energy system or the electricity network in a time segment of the series of time segments; applying the plurality of electricity generation values and the plurality of electrical load values to an electricity cost model to determine a plurality of electricity importation values and a plurality of electricity exportation values, each of the electricity importation values representing an amount of electricity the renewable energy system imports from the electricity network in a time segment of the series of time segments and each of the electricity exportation values representing an amount of electricity the renewable energy system exports to the electricity network in a time segment of the series of time segments, wherein the electricity cost model includes an electricity cost value representing a cost for powering the electrical load; controlling, according to the plurality of electricity importation values and the plurality of electricity exportation values, operation of the renewable energy system to import electricity from or export electricity to the electricity network in the series of time segments to match the electricity cost value. obtaining a plurality of electricity generation values, each of the electricity generation values representing an amount of electricity generated by the renewable energy system in a time segment of the series of time segments obtaining a plurality of electrical load values, each of the electrical load values representing an amount of electricity consumed by an electrical load powered by the renewable energy system or the electricity network in a time segment of the series of time segments applying the plurality of electricity generation values and the plurality of electrical load values to an electricity cost model to determine a plurality of electricity importation values and a plurality of electricity exportation values, each of the electricity importation values representing an amount of electricity the renewable energy system imports from the electricity network in a time segment of the series of time segments and each of the electricity exportation values representing an amount of electricity the renewable energy system exports to the electricity network in a time segment of the series of time segments, wherein the electricity cost model includes an electricity cost value representing a cost for powering the electrical load controlling, according to the plurality of electricity importation values and the plurality of electricity exportation values, operation of the renewable energy system to import electricity from or export electricity to the electricity network in the series of time segments to match the electricity cost value
