In brief, the invention relates in particular to a converter () comprising a plurality of rectifier arms (), making it possible in particular to rectify AC electrical signals available on the electrical phases (U, V, W) of an electrical grid. To balance the electrical signals coming from the electrical phases (U, V, W) of the electrical grid, and to limit a modulation amplitude of the DC signal generated by the converter () between its output terminals (S, S), the converter () also comprises a correction arm () that determines an amplitude of electric current flowing in a neutral (N) of the electrical grid and that generates an opposing electric current of equal or if not close amplitude. The invention also relates to a two-way charger () comprising such a converter () and one or more active double bridges (), such that an output (S, S) of the active double bridges () is electrically isolated from the converter ().

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.
