Abstract: A method, implemented by a centralized controller, for controlling a virtual power plant connected to the power grid. The virtual power plant includes a battery controlled by a local controller configured to perform primary frequency control of the power grid. The virtual power plant also includes a set of hydroelectric power plants each controlled by a corresponding local controller. The centralized controller provides a power adjustment setpoint to the local controller of the battery so as to compensate for a variation in the total power relative to an overall target power for the set of hydroelectric power plants, and the centralized controller supplies, to at least one local controller of a hydroelectric power plant, at least one power adjustment setpoint, calculated on the basis of a frequency measurement, in accordance with a management strategy for the battery.

Abstract: The disclosure relates to controlling electricity production by a facility of photovoltaic panels in order to establish a power reserve. A method is carried out iteratively and includes: issuing respective setpoints to a number k of inverters among the set of N inverters, so that each produces a maximum power, where k<N, the k inverters being determined for a given iteration of the method, and obtaining, from the k inverters, measurements of the maximum power respectively produced by the k inverters and storing these measurements in memory with N-k other measurements obtained from N-k additional inverters during preceding iterations of the method; estimating, by reading the contents of the memory, a total maximum power able to be produced by the set of N inverters of the facility, and obtaining information relating to an amount of reserve power to be established, and determining an overall power to be produced.
