A method controls a microgrid having at least one renewable plant of distributed renewable energy resources and at least one generator plant of distributed non-renewable energy resources, and each plant has a local controller. The method includes providing type and power size of each plant to each local controller. At each local controller, measuring the frequency and estimating the total power load demanded based on the measured frequency. At the local renewable controller, decreasing the frequency at which power is supplied when the supplied power falls below the estimated power load and increasing the frequency when the supplied power exceeds the estimated power load. And at the local generator controller, increasing power supply in response to detecting a decrease in frequency, and decreasing power supply in response to detecting an increase in frequency.

Method for controlling a microgrid

A method of controlling an electricity production station including at least one renewable energy source and an energy accumulation system, allowing an operator to commit, at an electrical distribution network manager, to a power profile Pthat the station will be able to deliver over a forthcoming time period. The declared power profile must, furthermore, comply with constraints imposed by the manager of the electricity distribution network. Non-compliance with this commitment may be subject to penalties. It is then incumbent on the operator to best optimize the method of controlling the electricity production station so as to maximize the electrical power fed into the network, while complying, in so far as possible, over a certain tolerance range, with the power profile commitment P.

Method of controlling an electrical production station

A method for managing power in a charging station for charging electric vehicles, the charging station including several charging points, the method is used to predict accurately a consumption of the charging station, with satisfaction of clients. The method includes determining a statistic model of occupation of the charging station, determining some scenarios of occupation of the charging station, take into account the statistic model, determining, for each power profile among many power profiles, some scenarios which are valid and some other scenarios which are non-valid, taking in account client satisfaction rate, selecting an optimum power profile among said many power profiles for which a number of non-valid scenarios does not exceed a predefined threshold.
