METHOD FOR DETERMINING PARAMETERS OF A SIMPLIFIED MODEL OF AN ENERGY STORAGE SYSTEM, CONTROL METHOD USING SUCH A MODEL AND ASSOCIATED DEVICE

摘要

One aspect of the invention relates to a method for determining parameters of a simplified model of an energy storage system, said system comprising an energy storage device and a conversion device, said system being able to be modelled by way of a complex model (MC) including a model of the energy storage device and a model of the conversion device; said complex model receiving a setpoint power P_{ac_sp} and a state of charge SOC_p at input and providing the state of charge SOC of the storage device and the power P_ac at the output of the storage device at output; said method comprising a first step of implementing a plurality of simulations of the energy storage system using the complex model; a second step of calculating, on the basis of the results obtained in the first step: - a table of the variation in the state of charge of the system as a function of the setpoint power P_{ac_sp} and of a state of charge SOC; - a table of maximum power as a function of the state of charge SOC; - a table of minimum power as a function of the state of charge SOC. The simplified model thus obtained makes it possible to assign a power P_ac and a state of charge of the system SOC as a function of a setpoint power P_{ac_sp} and of a state of charge SOC_p that are provided at input, and on the basis of the tables determined in the second step.
